How to remove moss from tiles without jet washer

[knittynoodle]

We live in a flat with a large balcony area. I've just moved all DP's junk collectables to find that the tiles are mossy underneath. I was hoping to make this into a play area for DS, but the tiles are nasty.

DP wants to lay lino over it or jet wash but as we live above a council office I am sure its prohibited. I realise I will have to get on my hands and knees with a scrubbing brush for this labor of love!

Any ideas for a non toxic cleaner that could remove it?

there are some good cleaners, especially Armatillox, but as they work by killing the moss, I expect they are toxic.

Moss will die if it is dried off. It may be that uncovering it and letting sun and air at it will dry out the surface.

Bleach would probably kill it.

Dead dry moss is much easier to remove than live.

If the surface is damp and you put lino vinyl flooring over it, the damp will be trapped under the vinyl and various interesting forms of nature will live and grow there.

I told DP that about the lino. He also wanted to cover the peeling laminate floor in the kitchen from a leak, while it was still WET so we don't take advice from him!

You think bleach then? Its mostly dry but the bits that I've brushed off have left black marks.

soda crystals can be used to kill moss and are non-toxic

I didn't know that

how fast does it work/how long does it work/how easy is it to get the dead moss out?

You could try this as it's not harmful to kids / animals etc

Slight disclaimer in that I am associated with the company but I believe it's very good although I haven't used it myself. My be worth a try as it says no scrubbing :o

curry

it says "Protects against algae and moss growth for up to 6 months"

so surely it must leave a persistent chemical coating that is toxic to at least moss?

I'm worried now that this will be seen as shameless advertising and I will be drummed out of MN

I do post a bit on other things and won't make a penny my millions if you buy it. Was just trying to be helpful [gets coat]

Piglet I don't know but I know it won't kill other plants I don't think. And it's certainly not "toxic"

I don't think she wants the moss to grow back does she?

The other chemical I know about is toxic to moss.

If it kills moss and algae, it must be toxic to moss and algae, no?

And if it lasts for up to 6 months, then its toxicity must persist for 6 months, no?

I don't necessarily object to toxicity. For example slug pellets have to be toxic to slugs, rat poison has to be toxic to rats, greenfly spray has to be toxic to greenly, and I use all of them. They have to be toxic to work. These chemicals might or might not be toxic to other organisms.
