2 x Algon Organic Path and Patio Cleaner Concentrate 2.5l

Excellent product. Not harmful to birds, animals or fish. Continues to lighten paths, patios etc for week after first use. Completely recommend.

Cleans the patio easily. Think it's aided with moss killing also.

Good for clearing algae/moss from drive.

I found this product again after using a competitor brand for the last 2 years and Algon was much the more effective rapidly killing the moss and algae. It is easy to use too with no brushing or rinsing needed.

Just make up with said amount of water brush on and leave. Works wonders on paths, patios and fences.

We have many Yorkshire stone flags in our garden. Have used this product many times as It is safe to use near animals and doesn't harm the environment. Very good results and keeps slabs clear for a long time.

Not greatly impressed.Moss is still there and there is a white residue on the brickwork.Perhaps time will tell ?

We use this product to remove algal growth on our polytunnel. It works well, and we have been using it now for some years. It saves a lot of hassle trying to mop the tunnel! I have not tried it on paths, but I'm sure, from its effectiveness on the plastic tunnel cover, that it will work well. This year has been more challenging with almost continuous rain, and it does need a bit of dry weather to take effect rather than being rained off.
