    This stuff is brilliant. Diluted it 5050. Sprayed it on using a weed killer sprayer, left it for around 40 minutes. Rinsed it off. Came up a treat.

  4. John Towers

    BRILLIANT Does exactly what it says. My dirty old patio is now looking as good as new. Would definitely recommend.

  14. C. J. Ward

    So Ive been using these for a few weeks now and Im really impressed. They are easy to use, simply putting one in before a main wash. My machine feels cleaner and clothes come out a lot fresher. And I believe thats dkento the tablets.

  15. Reviewed by Aquacadabra customer

    Amazing product Tried many other brands from cheap patio cleaners from local supermarkets and DIY stores to highend expensive brands but this product beats them all hands down Fantastic value for money, goes a long way and so easy to apply. We applied it to our Indian stone patio slabs using a 7 litre garden sprayer having pressure washed the worst off. You could see it working immediately. We left it on for the suggested time and then pressure washed it again but only lightly. We then spot treated again any stubborn areas. We have since done more patio areas and even left it on overnight with no issues. The photos show the slabs at the start, one heavily stained slab and then the last photo shows the end result the back section with nothing done to it, the right hand section just pressure washed and the front section treated. We are relaying all patio areas and cleaning them before we lift them. We will then be using it regularly to avoid having to pressure wash them so hard and the damage that can do to the jointing.

  18. A happy hippy (verified owner)

    I used to use Sainsburys own brand limescale preventer, but once when it was out of stock, I bought Calgon and Ive never looked back its better by far. Its better not only for limescale prevention, but keeps the washing machine freshsmelling as well. I find I can get better value for money by getting a larger box on eBay.

  35. Wildbill (verified owner)

    I looked at other well known black spot products theyd need to be outstanding to justify the price difference.Sprayed this on a block paved driveway with a garden sprayer overnight pressure washed it off the next day. Blocks came up really well but might need a few goes on a heavily spotted driveway. Ours was cleaned about 2 years ago Ive washed it every now then with the pressure washer so it wasnt really bad.This stuff does stink though, very bleachy as its sodium hydrochloride so its best used overnight or when its not going to annoy anyone.Ive only used this where needed and not the whole of the driveway, for the price its good value and will use it again but it cant be used near plants or aquatic life or where it will drain into them.

    Whats not to like about something that can extend life. Calgon tabs can do it for washerdryers and dish washers. Calgon keeps the machines internals clean and free from scale. So, both my machines, which are well over 10 years old, are performing just as well as when they were brand new. Thanks to Calgon.

  43. Tan (verified owner)

    I purchased this as an alternative to the much more expensive cleaning product from SmartSeal because I had not purchased enough to complete the cleaning of our sandstone patio. It has done an excellent job, just the same as the SmartSeal product as far as I can tell. Maybe the SmartSeal product about 4X the price has other cleaning agents etc which I will only discover when I come to seal the patio once it has dried but so far, an excellent outcome.

  44. speedy gonzales

    Ideal for my needs, thdo not have a long effective lifespan, as one does not have a large order sitting about, with a low free carriage limit, it is possible to get how much you want, without having to order too much from them.

    Calgon Limescale prevention tablets small pack of 15 pieces.Calgon has 3 neutralising actions1. Unbeatable limescale protection to prevent machine breakdown2. Antidirt action to avoid residue accumulation3. New antiodour actives the fight malodourI was using one tab in each washing. After few washing the clothes feels much more soft when unloading the washing machine and as well after drying. The conditioner scent is much more vibrant.Its easy single dose tabs so you dont have to measure the powder.

  137. JRaffaele (verified owner)

    Did an excellent job where it touched. Started applying using a watering can but quickly realised it wasnt going to cover area, so moved to spreading with a brush. As a result the finish was a bit blotchy but that was my fault for spreading too liberally at the start of the job.

  138. Spookydooky

    My washing machine was starting to make noise and bearing in mind that it is not even 6 years old,it was quite worrying.We live in a hard water area and everything has lime scale on or in it and I am constantly buying products to get rid of it.I have also noticed my machine had a damp smell when I took the washing out which meant the clothes had a damp smell too even after adding fabric softener to the wash. I kept seeing adverts on tv about adding Calgon to the machine as lime scale builds up and clogs pipes,which means the machine will,at some point,give in.I got these and have been using it for about 2 weeks now and can honestly say my machine is completely differentMy machine isnt making any noise when on spin and my washing actually smells of fabric softener when I take it out and I dont have to buy any other products to get rid of the damp smell.Now I just wish they would create a similar product for kettles.This product might have just saved my washing machine.Buying his product is like making an investment in your washing machine so it is definitely worth every single penny.

The job required only 20ltrs but 40 was used as the concentrated amount was certainly not 1415 strength. It cost me time and money and certainly will not be using this company for my supplies.

    To save money I was buying powdered limescale remover that I could put into the washing machine. Whether it worked or not I have no idea. However the washing machine was smelling almost loudly, though I couldntt see any mould in the machine that I could tackle. Having seen the advert I have tried the dalton tablets. I wont go back again, the machine seems cleaner, it appears to have dislodged some existing limescale little bits have come out of the machine when I have done a rinse and wash through and more importantly the mouldy smell has gone. Really happy with this product.

    For me the downside is that when washing on low temperatures the blue solid ball in the centre of the tablet does not dissolve completely and on occasions has left a blue stain particularly on white garments. However I have resolved this problem by dissolving the tablet in hot water, leaving it overnight and pouring it in the soap dispenser with detergent.

Wed forgotten what it used to look like…It took two coats sprayed on and we had to be super careful near our plants, but our Indian stone is transformed to new The photo is just after one coat… it looks even better now. Its potent stuff, so use a mask with a filter and keep away from pets and plants. We did try bleach and scrubbing method first, but it was such hard graft with little results, this stuff is what miracles are made of We now need to seal our patio to stop it getting into such a mess.

    Not overly impressed by this product. It did remove some of the lichen but not all of it. I used a pump sprayer to apply it undiluted and left it overnight as recommended. It took several washes and rain showers before it was completely removed from my block paving in places it looked as though the blocks were still wet.Be aware I managed to spray some of it onto the oak beams of a raised bed and it bleached them a much lighter shade than the surrounding wood. I also got some of it onto the casters of our BBQ and it tarnished the chrome. In retrospect it might have been better too apply it with a watering can to have more control over where it fell. Using a pump sprayer meant it drifted through the air. You have been warned.

  299. Daniel Taylor

    Slightly uncertain purchasing this product initially as normally I just give the patio an annual jet wash plus this seemed more expensive than other cleaning products available. However I was fed up with the ugly black lichen spots which seem impossible to shift with a jet wash and other products didnt appear to claim it would clean these.The price was worth it particularly as I bought a bulk deal from HSD. The product was amazing and has restored my patio to a newly laid appearance. Slightly awkward to use in that you had to be careful keeping pets children away and its clearly strong as a couple of splashes bleached my old clothes be carefulThe product was much quicker to spray on compared to hours of jet washing. After 4 hours the patio was clean you can see it almost dissolve the dirt before your eyes and had completely removed both the green mould and importantly the black spots . Another rinse down with the jet wash and it looks much cleaner and much quicker than my usual annual task. I dont think Ill use it every year as the black spots dont appear that quickly but Ill definitely use again. I should have done a before and after photo before these stones looked a very matt green grey with lots of black lichen spots covering them.

Just spray with a fine rose head on the watering can on or apply with a brush and leave. I leave it for about 20min and find thats long enough. Stubborn stains can have a second application. Just remember only apply to areas that need treated as it will kill plants and grass.

    This is the first time Ive used them. Ive recently bought a new washing machine and live in a very hard water area. I saw these on offer so I thought Id try them. Im impressed. After following the instructions and adding one tablet to the manufacturers recommended dosage for soft water areas, I was very surprised to see how clean my clothes were, as I only used 45ml of powder compared to the recommended dosage of 115ml for my water type Surf. I always thought items like this were overpriced and gimmicky, but price wise I will more than cover that in the saving I make on washing powder, as Im only using just over a third of what I used to per wash. Plus Im increasing my washing machines life. One final tip, drop one of these in your toilet cistern occasionally to reduce limescale buildup.

    Calgon Washing Machine tablets are designed to breakdown the buildup of Calcification caused by Hard Water within the Drum and workings of said machine. It does this effortlessly and each and every time you use one1 tablet with each washing cycle. This reliable and trusted product kept my previous machine working efficiently and without breakdown for more than 22 years. My new model is expected to last for many years in the future if and only if, I continue to use one1 tablet with each wash. Very Good Product. Would definitely recommend to another customer.

    Use for cleaning patio, path, roof and areas with moss, algae, lichen, black spot. Test the dilution can mix with up to six parts of water to one part of sodium hypochlorite I find two parts of water to one part of sodium hypochlorite is best for initial clean and use 3 to 1 for subsequent cleaning using a watering can. Wear old clothes its about seven times stronger than domestic bleach.

    Worked well to clean my 20 year old drive of both black spot and grey lichen. Jetwashing alone has not previously worked But this did the trick, raked out moss and swept it then put this stuff on and left it on overnight and jetwashed this removed black stuff and most grey lichen second application on bad areas got rid of the rest of the grey lichen stains.

    I had never bought Calgon before, but to be honest I hadnt thought about it until the partner and myself had a look at how gross our washing machine had become. I had noticed that some of my clothes had started to smell a bit different after washing and knew I had to take some action. I had heard about Calgon from the catchy TV advert and I was surprised to see how well these worked. They are really easy to use and noticeably there is less limescale. I dont think a tablet could ever make it brand new and shiny again, but this is good enough for me

    I live in a hard water area so we are prone to limescale build up so its great to know that I can protect my washing machine from it. With 3 children under 4 my washing machine is vital and gets an awful lot of use so anything to make it last longer is a huge plusSince I started using Calgon my washing machine has definitely lost its musty smell which sometimes occurred from the drawer so for odour control its absolutely fantastic.I would recommend and will continue to use in my machine

    It really does work I had a lot of stubborn black spots and with their instructions they came out. I am really happy w the results. Just a quick word that the product smells of bleach a lot so best to wear a mask when you are applying it.

    I bought these Powerball tablets as I was tired of having to scrub my washing machine trays every month with the buildup from the build up of limescale. This has left my washing machine smelling fresh and clean. It comes in a box of 15 tablets. Just follow the instructions and your washing machine will be fresh and clean.

My only concern is that the instructions say to use it in the drawer with the washing powder but I use a washing capsule in the drum so have just popped the tablet in with that too

    Unbelievable…… Pro Kleen not only removed all the black spots on our paving slabs, but cleaned them after so many years of neglect and brought them up looking like new. The 5 ltre can stretched a long way both front of the house and rear patio. You could see the Pro Kleen working virtually as it was being applied, and worked in a much shorter time frame than stated on the instructions for use. Will certainly be using it again to now keep the slabs clean.

    Easy to use Just add one to your machine drawer and the job is done I have noticed my laundry smells fresher and feels softer but I wonder if they would have worked better when the stuff was new, as the towels were already a bit hard even with fabric softener when I first tried these tablets. When I buy more linens, I will know better. Theory has it that less soap and fabric conditioner is needed if the water is softer so the Calgon is a worthwhile spend

    I wasnt too impressed the first time I used this as I was looking for immediate results However, over the next couple of days the application became easier and the results are beyond what I had hoped for. The stone slabs in the garden have come up as new and I am totally satisfied. It is quite hard work as I did not want to use a power spray because of the amount of flowers and shrubs around so I painted it on with a brush. This product is obviously quite potent so I would recommend old clothing and gloves, but other than that brilliant

    I used this in my washing machine mainly because it was beginning to smell and I just couldnt find out where it was coming from. I used Calgon twice and the smell has gone. It has most certainly improved the look of my laundry as well as I used to get brown stains on some of my washing but these have disappeared too. Im not using it on every wash as I think it works out too expensive and everything seems to be ok on every other or even 13 washes.

    I bought a new washing machine a couple of months ago and thought it would be best to start using something that would keep my machine as good as new on the inside. As soon as you open the individual little tablets the smell is just amazing, i love it. These calgon tablets are super easy to use, you just add them in the draw with your usual detergent and thats it, as the wash cycle is on the tablet does its job. Its great to know your inside of your machine is being kept clean from limescale all from one little tablet. When i removed my washing from the machine i couldnt believe how gorgeous my clothes and the machine smelled, this is a product i will always be adding to my shopping list.

    I live in a hardwater area and every waterbased appliance quickly clogs up with limescale. Ive had my washing machine for almost 5 years and so far Ive not had a problem. Despite not being able to look inside and see what effect its having, Im fairly positive that calgon is doing its job and helping to reduce the buildup and keep my machine going.

  838. Stefania cesiri (verified owner)

    This product was easy to use but extremely potent The fumes initiated some coughing so some sort of face mask should be worn. I left overnight and most of the back spots were easily washed away the next morning. I did feel it slightly took some colour from my slabs but nothing too obvious. Ensure you are wearing old, waterproof clothing as this is quite a messy job but certainly left my patio looking cleaner and brighter.

    Ive had black spots on the patio for years that the power washer just couldnt shift, this stuff lifted it in seconds. As soon as you apply it you can see the spots disappear. Leave it for a couple of hours and rinse away with nothing more than a hose. If you are covering a reasonably large patio and you want the product to go further it is definitely better to buy a pump sprayer, I ended up buying it twice as I just used a watering can on the first application and it didnt stretch to the whole patio. Id definitely recommend this product the patio stone looks as good as new.

  853. ArtySmarty (verified owner)

    Weve been using these since getting a new washing machine and in three months none of the black gunk we got in the old machine from our overly soft water has appeared. The machine is still pristine.It might not be the Calgon and over time our many washes a day from 2 sporty kids still at school and 3 dogs may take their toll but its looking good so far.And whilst the cost of the Calgon adds to the wash, the fact we arent now rewashing loads and using less conditioner because its all so clean means its well worth it.Obviously your mileage may vary if the machine is already in a state…

I noticed a difference after the first use it smelt horrible to begin with but as the wash progressed it smelt SO much better. It also helped to clear the washer draw as we dont usually use this as we put the washing liquid in the drum not the draw. I have continued to use these in almost every wash when the other half uses the washing machine he forgets and would definitely continue to use them as they are keeping the washing smelling fresher.

    Works really well, though tough spots need more than one application. Our 30×12 patio was badly affected by black spot, and will need 2 bottles.Photo 1 shows before treatment slabs look grey, but this is all blackspot, photo 2 after 2 applications.

  1014. mrtaxi27 (verified owner)

    Absolutely fantastic. Brilliant easy to use. No hard scrubbing needed. Amazing results. My patio was virtually black with dirt and black spot. I jet washed it which nearly made any difference. Then I used Black Spot Destroyer. The natural stone patio is now like it was when it was first laid around 10 yrs ago.

    Black Spot RemoverI have purchased from ProKleen before and found the product very satisfactory.This was my first experience with Black Spot Remover and again my results were satisfactory.The product was sprayed with a ProKleen spray and left the recommended amount of time.I cleaned it with a patio cleaner attachment, on a pressure washer and very little scrubbing was required. However, the amount of soapy type of suds concerned me at first. It is not clear if the substance has lost its strength at this point.Keep this away from all clothing etc. My wife and I ruined 2 pairs of jeans when spraying even with protective clothing..

    I have been using Calgon tablets for many years, and have been happy with the product. What happened This product is so strong smelling that it is unpleasant. Just unwrapping the tablet is unpleasant as a very strong perfumed smell hits you. I hang the laundry outside, on a long line , to dry. So it should be lovely and fresh smelling at the end of the day. Not so, since I started using the new tablets. Lots of people are allergic, or sensitive , to strong smells and perfumes. Not just smelling it, but also against the skin. Surely a product that is used to keep the washing machines clean, especially as it is designed to go in with the laundry, should have minimum of perfume. I am not happy at all. Using the tablets , my clothes feel uncomfortable to wear as they reek. Going to bed in a freshly made bed is so unpleasant and I cant relax, as it reeks. And no, I have not changed any other products. The only new thing is the latest box of Calgon tablets. I stopped using the tablets yesterday, I have quite a lot left in the box, and guess what……. The clean laundry is lovely ones again. Do I get a refund if tablets has been usedIf this is the new Calgon, then can you please introduce a version for sensitive skin, one without added perfume

  1038. jeremym5621

    I never really expected this product to work, as my patio was in a very bad state, and I was more or less resigned to the fact that it would have to be renewed.I tried out a small area first, and was delighted that the black mould started to disappear before my eyes. However, nothing was happening to the white spots. I left it overnight, then used a wire brush on the white spots, which came off quite easily.I have now cleaned about 50 slabs, and have bought some more of the cleaning product so that I can do the rest when weather permits. The neighbours are very curious as to how I got it so clean

    I did not think we would get our Indian Sandstone patio to regain its original pretty colours. It had gone grey with black spots and looked very unattractive. Pressure washer would not touch it. This stuff is amazing, it works incredibly quickly and with zero effort. There are some spots remaining, a treatment will I think get rid of those or at least diminish them further.Photos show the patio after treatment, also one and a bit stones after a quick trial run. The whole patio looked like this dirty stone. I couldnt be more pleased as I was worried we would have to dig it up and replace.

    Paving was badly discoloured even after jet washing, with grey marks that turned black when wet. As soon as the Prokleen remover was applied you could see an instant reaction and the true colour of the stone coming through. Absolutely brilliant. Picture is of travertine steps

    Very good removed most of the stubborn spots on my patio in one application. Also very efficient delivery

    Review of Deep Blue Sodium Hypochlorite 1415

  1187. Butch (verified owner)

    worked well, removing stubborn lichen that wasnt removed by jet washing alone. I sprayed the Black Spot Destroyer with a back pack sprayer and left it for 4 hours. then I jet washed again and almost all the spots were removed. Next time I will buy Sodium Hypochlorite solution because it is cheaper.

    It has restored my Indian Sandstone paving to nearly new, with the exception of a few stubborn rust marks and with minimal effort just as I wanted. Would highly recommend.

    It was used to clean my patio area which is quite large.It saves using a high pressure water jet , it does a better job much quicker without splattering water and dirt all over the windows etc.

    I used it as per instructions, it did a job but I was expecting a better result. Also, I think it is expensive compared to similar products.

    Im now using these tablets in my washing machine After having cleaned my machine from funny smell. I now use to keep machine clean and keep the Limesscale down, will take long term view So not sure how successful it will be.

    Amazing stuff, Ive put up with ugly black spots and black patches on my paving which nothing else would remove, even using pressure washer. I now have a patio that looks like new. You could see it fizzing at the black spots getting to work straight away. Would highly recommend.

    Its a bit expensive and the smell is pretty overpowering strong chlorine smell but it did the job, got rid of blackspot that other cleaners barely touched. Indian sandstone patio almost like new. Could see it working on the bit just done as I did the next bit as it starts to foam up a bit where it touches the black spot

    We purchased a property where the patio slabs were original approx 25years old. We were going to rip them up and replace, however, I used this product two applications and also jet washed twice and they look brand new. The neighbours have even came to say how amazing they now look.

    Product did not work on my black spot. Followed the instructions to the letter. No fizz, nothing happened. A waste of money.
