It removes mould from the patio very quickly. I also use it to clean the render on my house which it also does quickly and without affecting the colour.

Used on paving and extension roof. Wire brushed and swept worst affected areas first and then applied using watering can with rose fitted instead of sprayer. Doesn’t go so far but doesn’t dry out so quickly. Also avoid applying in hot sun. Results aren’t instant but seems effective

5.0 out of 5 stars So much easier to use

This is so much easier to use than a power washer and you don’t need to re-grout with sand when used with block paving. Just use a watering can to apply it and it starts to clean as it drys, full results start to show after a few days and it continues working for months. It’s good for many different surfaces, there’s no chemical smell and it gets rid of moss too.

Bought it to try on a concrete area that gets no sun at the back of the house. Treated the area, using a sprayer, on a dry couple of days and was well impressed with the results. What was green ended up white within 48 hours. Works well on slippery decking too. So much easier than dragging the pressure washer out of the shed.

5.0 out of 5 stars Great product, says 4 days to see results however working by next day!

Really good product. Used it once so far slightly more concentrated due to the moss, 1:4 instead of 1:5 sprayed about 3pm unfortunately rained over night and still killed the vast majority of whats been sprayed by the end of the next day. The thicker moss is still dying off but it is dying, 4 days and I think it will be dead. Do recommend and a good price against other products out there!

3.0 out of 5 stars PLEASE head this warning for Pets

Yesterday we used the 'so called' Pet and Child friendly garden patio cleaner (spray and leave variety) to remove green algae. Having diluted in the correct 5 to 1 ratio and treated the patio accordingly, our cat came out very briefly. After a couple of hours it became obvious that he wasn't himself after a period of grooming himself. We stayed with him and had him on the bed overnight but his condition didn't improve.We therefore called our local 24/7 emergency veterinary hospital over the bank holiday weekend and took him in. The initial prognosis wasn't great as he had a badly ulcerated tongue and throat. The fear from the surgeon was that it may have spread to the oesophagus and possibly vital organs.The surgeon contacted the toxicity regulatory agency to see what exactly was in the solution. He was told it contained a toxic substance!!! Thankfully this product is not industrial strength which is a good sign but our poor cat is being held on a drip and fluid feed and antibiotics.The latest update is that hopefully it is not the worst case scenario but the stress to the family, not to mention the cost, which will run potentially beyond £4,000 is highly concerning .LESSONS TO BE LEARNED.......The firms that advertise these products as' child and pet friendly' need to make it very clear that pets should be kept indoors until such time as the ground where it has been applied is completely dried. This does appear in very small print on the back of the container, however the large 'child and pet friendly' wording on the front of the container is totally misleading and misrepresentation.I hope by posting this that it will pre - warn potential purchasers but also encourage the manufacturer to make its product warnings as clear as possible to avoid the stress we are currently going through with the health of our cat. We shall be taking this further with the company.
