Amazing Product
We were getting green algae on some of our stine window sills and on North facing walls and on some fence panels. Sprayed with Wet and Forget and it gradually gets rid of the algae. Also sprayed patches of moss on shady areas of the drive. This quickly went from bright green to brown and gradually breaks up over time. I would definitely recommend it and am planning to spray our roof tiles to reduce the amount of moss and algae buildup.

Wet and Forget
Excellent product for keeping the paths clean. I have used a couple of times a year for years on Italian stone slabs that are difficult to clean and it keeps them looking beautiful.
Mr E Evans –
Worth the cost.
I sprayed my house roof tiles with this product during 1st year of Pandemic, and it cleared everything and my roof is still the cleanest in the street!!! Have now recently sprayed driveway and exterior walls. Great results. Worth the cost as it appears to be long lasting against algae and other growth.

Effective Treatment
I have read on some reviews that people are not achieving expected outcomes with this product. Cant understand that criticism at all. The mould and algae I wanted to remove has died off in fine style. It is fundamental that you mix the remover with the correct amount of water. I delivered the mix using a spray and ensured that the vegetation was well and truly soaked. Everything sprayed started to die off after several days

Brighter Cleaner Patio & Walls
I have used this for a number of years now, and I’m never disappointed. First time it is applied you need to be patient! It does work. Then just re- apply every year. I do that twice in the area the dogs go to the toilet on the flagged patio. It saves my back from from pain by using a power washer Also saves water and time.

Brilliant
A brilliant product which I have used for lichen removal for the past 5 years, Great for patios and walls, especially where pressure washing is not appropriate. However, one must be patient and let it do its work!
What June does –
Power wash first
We put it on first but it didn’t do much but then we power washed the patio and it came up brand new. I would power wash it first next time then spray wet and forget on

Effortless Way to Clean Patio
It works but do not use a spray as stated on the bottle. Put required amount of Wet and Forget into a bucket of water (water in first otherwise it foams up) then using a soft brush apply to the patio for example, agitating as you work the mixture into the surface. Leave to dry then let the rain and sun do the work. Do not be tempted to wash down with a hose. Over the coming months the surface will become noticeably cleaner but it does take time; be patient.

Tried and trusted … does what it says
Excellent for cleaning patios, decking drives, roofs and walls. Also kills weeds, lichen, moss and algae. Minimum effort or fuss. I have used this for years and not been disappointed. Less work and damage than a pressure washer. Need to be patient as takes several weeks before the cleaning effect is noticeable. Sweep the area first to expose all the surface. Recommend using a large garden sprayer with wand for ease of application.

Fantastic
Haven’t used this order yet but have used In the past.
Best stuff on the market not cheap and it does take a while to see the difference but what a difference it makes. Brilliant stuff 👍

Does What It Says!
To be fair I was sceptical when purchasing this as so many things get advertised but don’t really do what they say.Well we put this on some concrete plinths of fencing that had gone green and after 24hrs the result was amazing, so then done a composite decking that some planks had started to go green and that result was exactly the same. So I am now looking for other areas I can do would recommend it and follow instructions.

Great Product
Easy to use and works as described. Wet and forget. watch it work the longer it’s left to work on the Algae.
LLWM1509 –
Very effective
Great stuff and works within 2-3 days. I would recommend upping the ratio like I did to give you the right result, depending on the severity of the algae on your patio and driveway. I used a ratio of 1:3/4 so split the 5l container into 3 or 4 watering can fulls. We have a north facing patio, hence the need for a stronger mix. Would recommend. Make sure it’s a dry day and your keep pets in of course.

Removing algae
This is an excellent product and works as per the advertising. Highly recommend
Jeffff –
Saves lots of time and effort.
I’ve been using this from thinkassemble.co.uk for a year or two. I retreat the block paving every 6 months or so, and after a few treatments the block stays cleaner for longer. It’s as though the effectiveness of the treatment builds up over time. Get some – you won’t be disappointed.

Works well when diluted less
A good product that works well… but it needed to be diluted with less water to work really well.
