Wet & Forget Mould, Lichen & Algae Remover, Outdoor Cleaning Solution, Black Mould Remover, Bleach Free, 5 LitreCompact by Design (Certified by Amazon)

Looked for a while for something to get rid of moss, recommended this product by a friend. Results seen within a few days and so far seems to have been effective.

I used wet and forget on our patio flags & it killed all the moss/lichen after a few weeks. Just brush away any debris and spray on dry surface with no rain forecast for 24hours. But you must be patient as this can take a few weeks to work depending on how dirty the slabs are. Very pleased with the results

No jet washing required, just spray on and leave to dry and then the lovely British weather will do its work, used this time on paving slabs but have used on a conservatory roof, takes around 4-6 weeks to remove algae in fullEasy and quick to use.

Brilliant product that 100% lives up to its name!! Thought I might have to give a second treatment as path has been never been treated since installed years ago but literally all gone after one day! Easy to use with garden sprayer also bought on Amazon. Delighted!

**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. :)

I was a bit skeptical about this product, but thought I'd give it a go on my fence after watching a YouTube review. Mixed to the recommended dilution & applied with a garden pressure sprayer, the whole 60m fence was done in about 20 minutes. 3 days later and all the green had disappeared from the fence (except for some bits I had missed). I would thoroughly recommend Wet & Forget for use on a wooden fence.
