Moss on driveway, best way to remove?

[bettz1]

Hi I was after some adive on what's best to use to remove loss on a tarmac driveway?

I've a pressure sprayer which I could use cheap bleach?

Bac 50?
Patio magic?

Any advice? I'd also like to use it on my Indian sandstone slabs.

Patio Magic (and Wet & Forget) are basically dilute forms of BAC 50. BAC 50 is a 50% solution of benzalkonium chloride.

It depends on how thick the moss is. If I get round to doing my tarmac before the moss gets too bad then I just spray it with BAC 50 diluted to the right level. If I have let it get too thick I scrape the worst off it off first.

Lightly Hose down driveway.

Spray or Pour bleach as undiluted as possible onto moss or whatever you want to clean

Leave for a few hours or overnight

Pressure wash

Salt , cheap and destroys all plant life.

I figured I might aswell do next doors so it's a double drive.

Yes I keep reading about Bac 50 but I'm worried it'll damaged the sandstone if I used it on the patio area as well or would it bleach or damage artificial grass? It's fine to use on the driveway.

Looks like it's going to be a yearly thing

No real idea about sandstone, I have only used it on tarmac. But I would be rather surprised if it bleached anything, as that is not the mechanism by which it kills moss, etc. You could try it on an inconspicuous area.

FYI, I sprayed my front yard last Friday (5th) when it looked like this


By the following Monday it looked like this


I used it at a rate of 100ml of BAC 50 diluted with 1500ml of water.

Could well be. I have a very tatty, north facing front yard, so ideal conditions for it. If you can keep the driveway in good condition then there will be fewer places for it to grow in.

Biological washing powder has totally wiped out quite heavy infestations of moss in 4 -5 days for us

Do you just cover the affected areas and leave?

It must be Daz!!

Biological washing powder

is mostly surfactants, and BAC is used, inter alia, as a surfactant.

I've no idea is that is the mechanism by which it kills moss.

Just dust it over and leave, if its dry weather I just damp it down with a fine water spray
