Review: Mould Mould Go away no need to come back on another day - I’ll be honest, I went into this a bit sceptical. Outdoor cleaners usually promise a lot and then quietly disappoint, so I deliberately waited quite a while before writing this to see what actually happened over time. The difference is obvious. The before and after is night and day. Black mould, algae and general grime that had been clinging on for ages has genuinely cleared away without any scrubbing. It looks cleaner, brighter and just healthier overall, especially on areas that never fully dried out before. In terms of use, the first application I did with a jet wash because it felt quicker and easier for covering a larger area. That worked perfectly and made light work of the initial clean. Since then I have reapplied it every few months using a standard pump sprayer and that has been just as straightforward. Ease of use is a big plus here, fill it, apply it, walk away. No effort, no fuss. The functionality is exactly what it claims. You apply it and let it do its thing over time. There is no instant blast like bleach, but that is kind of the point. It keeps working long after you have finished applying it. Durability is excellent because the results last, not just a quick cosmetic clean that comes back after the next bit of rain. Quality feels spot on and the capacity goes a long way, especially when diluted properly. Power wise it is clearly strong enough to deal with stubborn growth without damaging surfaces. Value for money is very good considering how effective it is and how little effort is involved. One bottle has covered far more area than I expected. I honestly cannot fault it. No weird residue, no strong lingering smell, no damage to surrounding areas. It just quietly works. That whole too good to be true saying does not really apply here. This one actually delivers.
Review: Works well but give it time! - This is the second time I have purchased wet & forget and the results have been favourable in terms of eventually getting rid of algae, lichen and even moss for a period of time. I originally bought this to treat my block paving drive as I had what I'd described as white chewing gum stains and black spotty marks all over the area. I tried power washing and scrubbing with detergents but nothing seemed to work and then a friend advised to get wet & forget. I was a bit dubious it isn't a cheap option but I decided to give it a go and after 3-6 months I realised pretty much all the stains had gone! Now it certainly does not work overnight but I treated once and left (and genuinely fogot about it)... all the marks had gone, see attached pics of before and after treatment. Since then I have used my second container on my roof and even on a very old roof with high levels of moss growing. Here I did remove some of the moss with a plastic scrapper but the rest was down to spraying this product. It is so simple to do, just dilue 1 part wet & forget to 5 parts tap water, mix and then spray generously on the affected area. It is advisable to do this is dry conditions or when rain is not forecasted that day. Then wait, and over time you will see a difference. To conclude I am going to give this a full 5 stars it does actual work well. Only time will tell if it continues to work but in the case of my drive it remains clear of these marks after over a year+ period so I am genuinely happy with the results. It is not a cheap solution (there are lower cost alternatives which I have not used) but this one certainly delivers.

## Questions & Answers

**Q: Active ingredient ?**
A: The active ingredient in Wet & Forget is Alkyl Dimethyl Benzyl Ammonium Chloride. I think this is the same ingredient that is in many kitchen surface cleaners. This chemical has other names too I believe like benylkonium chloride. Benzalkonium chloride, also known as BZK, BKC, BAC, alkyldimethylbenzylammonium chloride and ADBAC , is a type of cationic surfactant which has antiseptic and anti fungal properties.

**Q: Once moss is killed from between block pavers do you have to sweep up dead debris?**
A: Yes, I would definitely clean any debris away, if you are removing green alge, it just disapearers after a few days

**Q: Is it safe to use on  patio that cat walks across**
A: Yep my cat and dogs walk on the patio spray on a dry warm day it dries quickly and starts cleaning immediately

**Q: We have a bad infestation of lichen on a conservatory roof.    Has anyone had good results at removing same?**
A: we have had lots of moss on our patio and on the shed roof and over 6 months it has cleaned the lot but you have to do it when it is dry and then the sun and the rain clears it, it is great no scrubbing just spray it on and leave it

### ⭐⭐⭐⭐ Goes a fair amount but pricey
*by W***W on 16 February 2026*

Small amount for the price but dilutes down so not bad value. Does not smell chemical and the bottle was well packaged on arrival, easy to apply with a spray bottle and no leaks. Seemingly takes a while for removal but our green algae on the wooden fence slats went almost instantly. It looks really good now. Was worried about the effect on nearby grass but this seems less damaging than other chemicals we have used in the past. The slats now look much better. Really effective and hopefully long lasting. This should avoid us having paint the fence this year. I did most of our fence and also a decent amount of decking boards, spindles and siding with the smaller bottle. A big bottle would easily do a whole garden.
