Lithofin MN Outdoor Cleaner 1Ltr OUT1

Used to clean artificial stone and it worked quickly and effectively for me. I had seen other reviews that said it smells like bleach (it does) and just to use that. I tried it and I did eventually achieve pretty much the same result with bleach but it took longer, more applications and more scrubbing - yes it’s expensive, but my time is worth something too. Ended up buying a 5 litre after trying a 1 litre. Whatever you use, PPE recommended and keep away from pets.

You open the bottle and you can immediately smell bleach. Says on the bottle sodium hypochlorite. Exactly the same as what’s in bleach. Domestics is 3.5g of it per 100g and that’s thick. This is watered down. Good on Lithofin for pulling the wool over my eyes. Yes it works but I know what I’ll be buying again and it won’t be Lithofin. Good for killing wasps as one flew in the way and died in 5 seconds. ***No mention on the bottle that avoid pets walking on the treated area. Bleach on paws, they lick them, they will be ill or worse.

I've tried all sorts to clean the slabs, jet washing (with powerful jet washer), bleach, scrubbing and never got anywhere - got to say i'm amazed by this stuff. I purchased the smallest amount just to do a small area and the results are incredible - see cleaned slab next to surrounding slabs all with lichen, black spots etc.The result is amazing and i can genuinely say the cleaned slab is like new.Only down side is this stuff ain't cheap and has to be left on for around two hours but the results are clear. Will be buying more!!

I purchased this clean the algae and brighten up my garden paving. It did the job to some extent but not at all what I expected. I would not recommend this product!

It did a great job of cleaning the lichen off my patio but I'm sure that the only active ingredient is sodium hypochlorite as it smells strongly of bleach. A 1L bottle doesn't go very far and I'm going to get the raw chemical next time, which is a fraction of the price.

Did what it was supposed to do

Followed the instructions. Tested 1 stone first. It did not do a thing.

Stone me, it worked well.
