Wet & Forget - Moss Mould Lichen & Al Remover (2 Litre)

This product is the best on the market and worth the cost. My fences have looked great for years with a treatment every 5 to 7 years or so. Plus unlike high pressure cleaning, it doesn't remove the pine wood treatment meaning it is clean but not exposed to termite damage.

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.

Trying different concreat mold remover over the years .this is the best one i.ve got so far.

This was sprayed onto a heavy lichen infestation and had started working by the next day with some lichen falling off. Very happy with these results

I used this in November 2024, yes that right and I am writing my review in May 2026. A whole 18 months later. Firstly those who thinks its cleaner like washing up liquid! Its not, you apply and leave it to work, you don't rinse it! Hence the name! Wet and Forget. On the container it even says results could take up to 6-12months. Do not expect results in hours, days or even weeks if they are stubborn! I spent a good 3 hours spraying it and noticed 3 months later that my back garden slab area looked less grimy, another 3 months and the front paving looked a little less grimy to now a whole 18 months later and the front paving is back to its original colours and you can clearly see the red/yellow/grey bricks. The back garden grey slabs looked bright and the crazy paving area no more moss. Like most I wasnt expecting a miracle but I am pleasantly surprised. If you havent the patience and want results fast then this is NOT the product you seek.
