Green Clean 5 litre bottle

I have been using this stuff for some years and cannot rate it highly enough. It does get rid of green algae (and other colours as well). Don't expect it to be instant; allow at least 24 hours, but it will get rid of it. If what you are putting it on is absorbant, like wood or brick or stone, then it keeps it green-free for months. If it is not absorbant, like metal or plastic, then it will get rid of the stains, but they will come back quicker.Decant it into a spray bottle and use it around the garden for exceptional results. It's safe to use. No, I wouldn't drink it anymore than I would drink washing-up liquid, but it is not some lethal concoction that will make your cat drop dead if it walks over an area you have treated.As an example, some fence panels at the bottom of the garden that were in deep shade had gone completely green. Sprayed them with this and went back to have a look two days later. It was easy to see which bits I had missed, as they were still green and the treated bit was wood-coloured. I don't expect to have to re-treat the same area for at least twelve months.The first one I bought was from QVC. You get twice as much product from Amazon for about the same price. A real no-brainer!

This was good at removing green from fencing. It also killed moss on tarmac. It had no effect at all on greening and lichen on patio and brickwork.

DID NOT DO AS WELL AS EXPECTED ON MY DRIVEWAY BUT I KEEP PERSERVERING

Used Green Clean on my patio . It is easy to apply and it works. Only used it spring 2014 so don't know if the effect will last but I am pleased with the results so far.

This is a great product for eradicating moss from the garden. Working equally well on brickwork, wood and paving stones. Simple to apply, and that is all there is to it, as long as the weather is dry for a couple of days, one sees it working in a relatively short space of time. Great stuff.

Really great product. Does exactly what it promises. My balcony was a mess. The wood was covered with varying combinations of green and black slimy substance. Could see the difference after the 1st application. No need to scrub. It just seems to 'eat' away the mould. Have needed retouches subsequently to keep it looking good. My only reservation is with the company I ordered from which never seemed to have more than 1 for sale at any given time. This means I have not been able to combine delivery charges by say ordering 2 simultaneously.

Did exactly what it is supposed to do. Good and easy to use.

Worked quite well but not as good as expected
