Mould, Lichen & Algae Remover 5L

⸻ ⭐⭐⭐⭐⭐ Amazing Results With Zero Effort! Wet & Forget is honestly one of the best outdoor cleaners I’ve ever used. I applied it to my patio, fencing, and the side of the house where mould and green algae always build up. All I had to do was spray it on and leave it — no scrubbing, no pressure washing, nothing. Within a couple of days I could already see the difference, and after a week the surfaces looked like new. It works exactly as promised and keeps the area looking clean for months. It’s also really easy to use and covers a good amount of space. If you’re tired of constant scrubbing or slippery green patches, this product is an absolute game-changer. Highly recommended!

Does exactly as advertised. I recommend it.

Brilliant product . Our limestone patio was very green with all the wet weather . One good coat of Wet and Forget has restored the patio almost immediately. Have enough in the bottle when mixed for two more coats . Be interesting to see how clean it stays ..

This stuff is just great, so pleased I found it. I hated jet washing my two paths and two patios so tended to keep putting it off until they were black. I used this last spring with a small battery powered hand sprayer and gradually over the next few weeks the patios got cleaner and cleaner until they looked like brand new, and still are now in December. I used 2.5 ltr and have 2.5ltrs left . Which I will use again in the spring. One of my best buys

I bought Wet & Forget after hearing good things about it, and I have to say — it completely lives up to the hype! My patio and garden path were looking pretty green and grimy, but after one application and a bit of patience, the difference was incredible. The best part? No scrubbing, no pressure washing, no effort — just spray it on and walk away. Over the next couple of weeks, the mould and algae started to fade, and the paving slabs now look almost new again. It’s honestly kind of satisfying to watch them slowly clean themselves. The product is easy to use, doesn’t smell too strong, and covers a large area. I also like that it helps keep surfaces clean for months, so it’s great value for money. If you’re tired of spending weekends scrubbing patios or decks, this stuff is a game-changer. Just spray, forget, and enjoy your clean outdoor space!

**Scroll down to the very end for my UPDATE. To any reviewers that discredit my review and claim it's not real, sounds too vested in this product. Here's my HONEST original review: Having just used this, I can honestly say it looks worse on our indian limestone. I'm hoping it look better soon. Having done a lot of research before buying this brand, I've learnt a few things: • If you plant to treat lichen I.e. black spots on your stone, do a second treatment in rapid succession after the first. About 20 minutes apart. • The product states to make a mix of 1 parts concentrate to 5 parts water. Make a higher concentrate if you want a more rapid result. **Some reviewers have said it can take atleast six months to notice a difference. • Power washing after using this defies the point of using this product. Not only will you get this toxic substance airborne with a power wash, but, using a powerwash alone, will gain the same result without buying this solution. • I'm going to reapply another treatment tomorrow. There is no way I'm waiting six months for a noticeable difference. You might find you need to order two drums if you want to apply a second treatment right away. This drum makes about 7 applications. i.e. one full watering can (10 litres) equals 1 application. This means 1 part solution to 5 parts water. • You would be able to extend the usage of the solution by using a knapsack, but you will end up getting the solution in places you may not want it, due to the finer mist. Such as a fishpond as in our case or on our ancient dry stone wall which is teeming with beneficial insects which pollinate our fruit and veg. • The substance is toxic to wildlife when wet. Pets should be kept indoors, they say, until it's dry. Yes, it will make a difference to the local fauna in the shorterm, anything that crawled, slithered or scuttled on it, lost it's life. **ALL OF THE ABOVE WAS DEDUCED DIRECTLY FROM THE INSTRUCTIONS ON THE DRUM. IT CAN'T BE DISPUTED!!!** **UPDATE** Just to make it clear, I followed the instructions to a T: Application on a DULL day. No forecasted rain for the prescribed time. This Product takes MONTHS to work. This is my honest review. I gave up seeing an effective difference with this product in the short-term. By short term I mean 3 to 4 weeks. I couldn't see it making a rapid turnaround even if I left it a month or two longer. If you want an immediate difference, to enjoy your garden, for example, in the summer, you may have to resort to more drastic measures. Here's what I did: • I used a bottle of undiluted household bleach to one slab as a "test slab". The bleach cleared the slab by the following morning. • I then applied a 25/75 solution to the rest of the slabs of bleach to water. The result is far better than this solution. The 25/75 mixture didn't give the same results as a 100% bleach. It is however very passable and looks like one year old slabs as opposed to the 'freshly laid' look I was looking for. So to round off, if you are resolved to using this brand's less abrasive solution, plan ahead. Preferably 6 months in advance. If you want an immediate change, try another mixture. The bleach method worked better for me. I really hope you've found this useful. :)

very easy to use and works well

Fab product and works! Have re bought each year

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 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

Great for mould and algae removal and easy to use.

Great product and good value with Prime

Once you are able to work out the mixing ratio volume, spray the product in accordance with the instructions and it works very well. Well worth the cost.
