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.

Fantastic product. Was sceptical about whether it would remove the black spots as i had a major problem with black spots on my patio. Tried jetwashing it first which cleaned the patio but didnt really remove the black spots. This product has removed the majority of the blackspots. It has transformed the patio and the patio now looks amazing. Would highly recommend this product. First photo shows a partial area of the patio before any product was used and an area where the product was applied

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..

Calgon keeps the washing machine free of limescale and keeps it functioning perfectly. Good value for money
dahlim01 (verified owner) –
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.

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.

weemagsman (verified owner) –
First time I have used these and I live in a hard water area which can be a nightmare for all things using water. I find it has been really good at keeping bad odours away in the drum that I usually get when I use high temperatures to wash.

Amazing stuff totally cleared black spot from slabs, looking like new. Quite dear to buy but would use again.
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.

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

Excellent product does what it supposed to do. Do need quite a few containers as you use it neat. Need to wear old clothes, rubber gloves and protective mask and goggles,as its a strong mix, and will take colour out of any clothes if spilt or touched by the gloves.Would definitely buy and use again. Also good prompt quick delivery from this company

Excellent bought my paving and drive up wonderfully well with no effort. You must check suitable for the stone type. Below tester for pavers and patio stones before and after. Even cleaned the black of bricks that were under our camellias. You must not get on vegetation.

Been struggling to get algae and black spot off my drive for years. Tried all sorts of pressure washers and commercial drivepatio cleaners. Saw this stuff on YouTube and gave it a go. So glad I did. Have had to use a very strong solution 5050on some stubborn areas but its working. Drive and patio coming up a treat.
Sharon T (verified owner) –
Excellent for general cleaning but requires multiple applications to remove black spots.Some stubborn black spots it wont remove.However, will keep trying unless I find a better product.
Reviewed by Aquacadabra customer (verified owner) –
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.

Calgon is the industry leader for erasing limescale etc. With 45 tablets in the box it is going to last for 45 washes which is brilliant.
Vivi L. (verified owner) –
First time Ive ever used Calgon and I must say Im impressed . Even though we cant really see whats going on behind everything I can already notice the clothes looking cleaner, the drum itself always had a smell that made the clothes smell dirty even after a wash that Id end up washing twice.The machine doesnt have any smell and the clothes are actually smelling nice of the detergent Ive used which is awesomeThis has to be my 4th machine and I can say now Ill definitely be getting calgon again and again to keep my washer healthy and to make this one last

Absolutely fantastic product for hard water areas, which we live in. Have noticed the difference after a couple of uses already. I had terribly build up of limescale in my dishwasher, and felt that it was not working effectively. I started to use these and the difference has been amazing Would recommend

Amazing Calgon tablets to keep my washing machine clean and smelling nice and good price.
Rina (verified owner) –
Calgon is such a brilliant product, it not only cleans the washer, it cleans out the pipes, the drains and the water runs out at a perfect speed, it must actually clean the drainage pipes as well. As long as you follow the instructions and use a tablet in every wash, no smell and beautiful clean washing. I definitely recommend this product.
Caribbean Aviation (verified owner) –
Despite initial skepticism the product worked just as it claimed. Some black spots required a second treatment but the overall result is a perfect spot free patio. Would certainly recommend.
Mindfulness&Tranquillity (verified owner) –
Doesnt go very far with my professional spray container not least because it takes a number treatments to get rid of the stubborn black spots. It does not get rid of all stone stains however.
Saqqara (verified owner) –
Excellent product that keeps washing machine clean and in good working condition. Always pop a tab in a load.
Jungle Elephant user for more than 20 years (verified owner) –
Did a good job overall. Took two applications with second left overnight. Removed surface dirt with power wash first. Finished with a final power wash. 95 of black spot removed. Good product as value for money compared to others.
