    Had green algae on the patio, simply mix this with water using a watering can, pour it on. I used a brush to scrub it in, then one additional layer poured on. Within days the algae had gone and the patio is looking 100 better. Very easy to use and would use again.

    I use this every year to transform my patio from a slimy green mess to one that shows the true colour of the stones. It does not actually clean the dirt off the patio though you may still need a pressure washer if yours is really dirty. Nevertheless the green algae and moss is banished for months.

    Does exactly what it says on the tin. Id almost given up on the idea of having a safe, slime free path but then I came across Deep Blue, 2 days after treating the area, all mould, algae and moss had gone. I made up the solution in a watering can, sprayed the path and left it. There was absolutely nothing to it no hosing, brushing or scrubbing. Fantastic

    I mixed this in a watering can and poured it on to my patio in the spring time as it had gone green in places over the winter. Within a few hours the green staining was gone. Less messy than pressure washing and also it means you are not risking blasting the glaze off the slabs or the pointing out from between the gaps.

  131. Anna Gulyas (verified owner)

    I purchased this to clean the patio which had gone very dirty over many years. The cleaner worked and the patio stayed cleaner for quite a time. However, with all of the damp weather we have been having in the UK it needs doing again.I would use again as this is quite a heavy pack to carry home.

    This is just an incredible Product I saw it demonstrated on QVC and it really is as good as they say. I used it on a cream stone patio and garden walk some 35 years old. It all looked a dull grey but the original cream colour started to show through within 24 hours. Each time it rains it is reactivated and the results continue to improve.I bought this for safety as I did fracture my spine slipping on the steep icy drive some years ago, and it is now completely clear of any remnants of lichen in the flags so no longer gets slippy when wet.I shall be using this every year now, as apparently it continues to work for about a year.Wet and Forget is one of my best ever discoveries

  138. Beth Betteley (verified owner)

    Ive used this product before, and its just brilliant. It really is as easy as pouring the right amount into the garden sprayer so the dilute ratio is correct, and then spraying it aroundIt may look a bit pricey, but it saves you loads of time, as whats the alternative Spraying a load of Jays fluid around, scrubbing with a yard brush, waiting for a while, and then getting the pressure washer on it. Or even just pressure washing this is just far easier, and the results last much longerI bought the large size, as I have quite a big area to cover. 3 patios at the back of the house, a side passage from front to back, front area by the door and a path to the road. Also wanted to try it on the fence, and parts of the double drive. Did it all and still have some left The results on the patios paths, took probably 23 days . This time of year, they all get quite green with algae, and thats all gone now. The fence is quite unbelievable, its got rid of all the greenbrown algae but did take a bit longer to clear completely, maybe 10 days. Drive not sure about as its tarmac, and hasnt been dry for months due to the time of year, so Ill reserve judgement on that.Its very easy to apply using a standard garden sprayer, and I found I was actively looking for additional things to use it one when I had finished.Very happy to recommend.

  139. John Daniels

    A great product. Used in accordance with the instructions and it was amazing how the moss and algae have gone from our driveway, pation and paths.

  140. Paul Sloley (verified owner)

    Spotted this on QVC first, and as usual did my price comparisons. There wasnt much in the cost by the time you add carriage, but having sprayed my patio before the winter months, and seeing the results now no comparison to this time last year. I am a convert. Deep Blue has made a tremendous difference in keeping off the moss, and retaining the colour of the flags Amazing Will definitely buy again.

    I have been using Deep Blue for 3 years now and have been fairly happy with it according to the price I paid which was under ten pounds per 5 litre container as sold here last year. I do not use it with a sprayer but prefer the watering can with a sprinkler attachment method and on that basis providing that you pour your diluted Deep Blue fluid when the weather is dry, it works for a few weeks or maybe a couple of months according to your strength of mixture. I had always previously used a 41 dilution ratio, which is quite strong and will kill moss growth. Obviously the stronger your mixture the more containerslitres that you will require. Even with that dilution ratio this product does not offer permanent algaemoss removal and because of that I feel that there is no way that this product is worth todays asking price of just under seventeen pounds being that we required 25 litres each and every year…. noting that the algae will always return on both driveway and patio etc., even on this heavy price. Our alternative, and the algae will still return, is to dilute good quality bleach into our watering can where we have found that it does the same job but a whole lot cheaper. The cost of the bleach, around two pound fiftyish for 2 litres. supermarket price effectively achieving huge saving with exactly the same result. Again I apply when dry and leave overnight. Pets, or anythinganybody else for that matter, should be discouraged from walking on the wet patioarea during the drying period. As with Deep Blue the bleach thingie is still not a permanent solution but at least affordable. All IMHO of coarse.

    I put this stuff on, waited a week or two and was completely underwhelmed thought, well that was a waste of money. Fast forward three months and my drive and patio looks like fairies came and pressure washed it You have to be patient, but it really does work and its dead easy to use.

  173. Mick Haydock (verified owner)

    I was a bit dubious about buying this product as it only had one review and I have tried all sorts of cleaning agents to remove linchen black spots from my patio as can be seen by the pictures it works brilliantly and in no time at all, the first picture is of when I used a jet washer to clean the patio this highlighted the black spots. the second pictures shows the patio after applying the product I used a ratio of one part solution and three parts water and simply used a soft broom to spread the solution and in a matter of minutes I could see the difference. This has got to be the best 25 spent in ages, I would recommend this product.

    Having used this product before, but finding it harder and harder to locate at garden centres, I tried Deep Blue …. I was delighted to a find it, and b see it was the same price that Id paid over 2 years ago. I was slightly surprised to find that the formulation had changed from a blue liquid to a clear one, but can confirm that it works as perfectly as ever take one dry day, one watering can, and follow the instructions …. and two days later the oncegreen patio is spotless and so is the wooden fence Id never tried that before. Marvellous

  184. Nicola DAmico (verified owner)

    I cant believe this product. I have a patio that most of it doesnt see the sun and some never. Every year for nine years we have had to clean it regularly to stop it going green. In March this year we put down Deep Blue and never saw the green again. Just to reinforce things, and to see us through the winter, when I assumed with the damp etc the green would reappear, we put some down in October. It is now mid January and not a sight of green. It remains the same. It is also exceptionally easy to put down. All you need is a watering can and a broom. I cant rate this product highly enough.

    My wooden garden furniture goes green over the winter and usually requires hours of scrubbing. I sprayed with Wet and Forget and the green disappeared and has so far not returned. It was also good for getting rid of the green algae on my Yorkstone patio but the black mould is still persisting. The vendors say it will disappear with time we shall see. Am about to try it out on my roof tiles which have a fair bit of moss on them. Very good customer relations helpful advice.

    Very disappointed with this produce, Ive used it before and the Indian Stone patio came up beautifully, not this time it didntIve still got chewing gum Algae as well as the black stuff neither have budged, I wouldnt mind but when I apply it if anything Im over generous when spraying and weve had plenty of rain to reactivate it, plus its not cheapI wont be buying it again but go back to my power washerIncidentally it took the algae etc off the north facing fencing almost along with my garden shades paint

    My patio was covered in dirt and green algae, shame I didnt take a comparison photo.I have used many cleaners in the past which havent done the job, will definitely use this product again.It was very easy to use, please remember to rinse really well if you have pets or any visiting wildlife. Brilliant product.

    Been using Deep Blue for years. Spray it on and just watch the black mouldy form paving in my front garden return to the colour it was when new. No effort……..I recommend this to everyone.

    This is excellent stuff Its the second lot that Ive ordered and does exactly what it says in the product description. I used to power wash my drive and patio, but found that the results were very short lived. With Wet and Forget you just spray it on at the required dilution and wait. Within one week you will notice a difference and the improvement continues over time.

  233. ButterflyChimes

    Deep Blue is amazing It will save you karchering . All you have to do is make sure your patio stone or brick is dry apply Deep Blue and make sure the next day is going to be dry too .Hey presto one clean moss free patio terrace . It truly works . If stone is vey mossy and dirty you make need 2 applications but believe me it saves you lots of work .

  234. Chiara Manfrin

    Excellent product. It can take a while to work though. I used it on patio slabs and block paving but left out a small area to test whether it would work. It clearly works very well as the untouched area was black after 10 months. Still need to refresh it every year but much less hassle than power spraying.

    I have used this both in the spring time and another treatment just before the bad weather starts on my decking, patio and brick paver driveway. If I am only going to apply once a year, I will use a stronger mix and it just keeps all the mould and green stuff away allowing us to use the patio and decking without having to clean it first when spring comes around the corner.

    I purchased Deep Blue from COSTCO for 18.99 for 5 litresHave used the product as per instructions. In hindsight it would have been better to pressure wash the areas of patio, paving and walls first and then once dried a thorough application of Deep Blue. Yes it does exactly what it says in the adverts but is not a cleaner. We noticed a reduction in moss and mould over a couple of days but according to other reviews it can take months before it takes full effect.We want a clean, mould and moss free area quickly and its the clean bit that we want immediately. To sum up were pleased with the ongoing improvement from applying Deep Blue but suggest you clean all areas prior to application.Also make sure youve got old clothes on as any splashes will leave marks on your clothes similar to burns cause by bleach.Oh and if youve got more money than sense buy it here rather than COSTCO where it sells for 18.00

    Really impressed used on my Indian sandstone patio as some of the pointing had turned green and also need the seal the patio used a low pressure hand pump sprayed making it easy to apply. The result 24 hours later was that 90 of the alge had gone and the rest washed off using a garden hose . Also some on a bit of old concrete near a drain and most of that had gone very happy. Had previously used Deep Blue which was half as good in my opinion.

  250. Alan Keys

    Read about product previously and raving reviews.Our patio is 4 years old and had already got speckled brown mossalgae marks.Had tried other products, but as I have pets, I wont use anything that isnt pet friendly.Keep animals off until dry, then they are fine.In a month….the patio looks like new, you will need a decent sprayer, which we have now upgraded, as it helps.Have already purchased another bottle.Very impressed
