5 Litres - Simply Spray & Walk Away Concentrate Patio - Fencing - Decking - Green Mould and Algae Remover Killer (15L Simply Spray)

I've bought this a few times now and it really does work, spray at the start and end of summer to keep your patio looking good. I've used on Indian sandstone and found it more effective than other brands.

I was sceptical about buying this product. It seemed to be a hit or miss with the reviews I read on it. I had major surgery done and unable to a lot of things that require elbow grease. I have been waiting for a long time for someone to come and clean my yard as it was so green and the moss was starting to cling and spread everywhere. It was very slippy also.I decided to purchase this and have it ready for when someone comes to do the yard.When it arrived and I read the instructions and how easy it was to use, been a female I decided to give it a go myself. I was amazed at the results.The weather was nice and dry and I could see a difference each day and after a shower of rain it brought it up so clean.I dont need to rely on anyone now as the job is done and I can't wait to do the patio at the front of my house.Simply spray and walk away is all I had to do.The price is very good and I would buy again.

Although it did do what I wanted the results were not as dramatic. I feel a bit let down now as the moss etc is beginning to return. On the first spray it did kill it all and made the paviors cleaner. It may work better on fencing and decking but I have none of that. I don't like to jet spray as that removes all the sand. Will have another go later in the year.

Have used this brand for several years on block drive & slabbed patio. It has always proved effective in eliminating green algae & moss & leaving slabs like new, even when you start with very dark & dirty slabs. I apply twice a year

A bit of a curate's egg. Does kill moss; not convinced it cleans though. I used it on a large area of block paving, applying with a 5litre spray, and left it for three days. Moss died quickly enough, although it appears to affect other weeds in the joints selectively. One patch Of paving I missed with the pressure washer last year still appears darker than the rest. However, it has killed the moss in the paving joints and saved me a couple of days hard work wire brushing joints which is what I did last year. I would buy it again, but accept that I will still have to pressure wash to clean the blocks properly.

I was sceptical and pleasantly surpried at how effective and easy to apply to areas of my concrete drive than had turned green. One application was all it needed to remove moss and algea

This is a great product to get rid of algae, moss etc. on fences and sheds especially useful prior to treating/painting (takes about 2 days to clear it). Also works on patios (please note it kills but doesn't remove moss immediately, that needs to be done manually with brushing or power washing or letting it decay naturally). I have also used it on a concrete bird bath and other garden ornaments and it works well. So easy to use and it makes a real difference especially on north facing surfaces that are liable to become green with algae (I have also used it on our roof tiles). Doesn't kill black lichen which is notoriously hard to remove, but then it doesn't claim to do so, so I would say it lives up to its advertising. As hubby says, he daren't stay still otherwise I will spray him!

i had been looking at a product that would clean up my walls pathways,patio etc. and had initially been looking at a well known brand wet and forget, however i found this product very expensive and so researched some more. i then found this product spray and walk away so i initially bought one 5 litre and took to spraying the pathways and patio..and within the first 3 days there was a good difference. so i went on to purchase another 3 drums and since then i have done most of my outside with it including my pebbledash walls and they have come up beautiful! i must say i was so impressed that friends have noticed the difference also, and have puchased this product on seeing the difference it has made to mine. overall this is a product i would highly recommend and i will continue to purchase this for many years to come. ps only effort required is to mix product into sprayer spray area reqiured and have some patience ' it really does work' and keeps working for several months!.
