How can I remove lichen from the patio?

Loads of it! Looking at Wet and Forget but is there something else ? I've seen vinegar mentioned.

Thanks in advance 😊

Mostly people not wanting to slip and fall in wet weather.

Yes, quite. Already have mobility issues and am unsteady,it needs to be as safe as it can be. Absolutely nothing scorched or sterile about our garden.

lichen means you have very clear air. Why would you want to get rid of it?

Our garden seat is thick with it and I think it looks wonderful!

So is ours, I also think it's wonderful, don't want to slip on it on the patio though as I've already explained.

I have had my patio slabs down for 35+ years, have never once cleaned them other than a sweep and to dig out weeds from the cracks, and nobody has ever slipped over. Not once.

Jesus,I feel like I've wandered into AIBU 🙄

Just because YOU haven't fallen it doesn't mean that other people haven't,I have already slipped and broken my leg in 5 places,I don't want to risk doing it again. I'm so glad you are steady enough not to slip,I am not that's why I want to clean the patio.

We had moss taking over on our drive. Bought a box of biological washing powder and sprinkled it all over at bed time so that it looked like it had been snowing.

Next day the moss was turning black and crispy and was easy to sweep up.

It's never come back.

One box of arm and hammer to 2 gallons of warm water in a sprayer. It has eliminate moss on my patio without affecting trees and grass surrounding patio. I used more expensive and more aggressive methods and this worked best. I used it 2 summers in a row and this year no moss at all

It's not moss though,it's lichen,wonder if it would still work? Went to be googling last night and soda crystals seems to be a good method.

Algon is the only solution I know that is pet friendly and not a problem if it gets into watercourses.

Thanks, I'll look it up 😊

Are you sure you're taking about lichen? It's usually rough, not slippy

I lived in a house with old Edwardian paving slabs, they were impossible to walk on sometimes, so slippery. I looked for a solution that was quick to get hold of and found the one I mentioned above, the vinegar and washing up liquid mix. It cleared what was on them.

Currently have hideous orange bumpy tiles that were obviously the cheapest option for the people that put them in, the black spots only come off with intense, continuous pressure with the pressure washer. There is a special nozzle for it which I discovered by looking at YouTube videos. It eventually removed most of it, but nothing shifts it all. Fortunately it is possible to put pots over it.

I use hot tub chlorine for mine, give it a scrub with some hot water and it comes up beautifully

Kills everything, how lovely

There's really no need to get annoyed. The point I was making was that the lichen that's been growing on my patio slabs for decades has not made it slippery underfoot.

Again,that's great but I'm not risking it.
