Removing Moss and Grass from Driveway

I just use the cheap bleach from Aldi or Lidl, dilute it 50/50 with water and spread it with a watering can. It kills the moss within a couple of days but leave until you have a spell of dry weather before taking a brush to it. Cheap fix.

That is more like gravel than tarmac, if it's tarmac it's pretty loose looking stuff, I'd say you'll have to settle for just killing the moss and hope it rots away.

Either of these PAC cleaners. Just used pro one a couple of weeks ago on two large driveways, all moss brown (except the bits I missed). Tried and failed with the detergent, bleach and other crap previously. This stuff works.

Per a suggestion on here o used bio washing powder from Lidl, our aldi is awkward for me to get to, a d I sprinkled it over moss in front of garage.

Great success.

I believe the washing powder should be bio, wherin it contains enzymes, and that it's these that do the deed. At least that's what I use, and it works.

It also works on algae. I have a concrete apron around my house, and with time it goes near black. A couple of months ago I pressure washed one of the worst sections that had actually become spongy under foot with an alagae/proto moss mix, back to bare clean concrete. Just a month or two later and it's green again. I mixed some Lidl bio washing powder with water and used a stiff bristled broom to lightly scrub half of the green concrete to see if it would work. It did, so half the concrete is green tinged and the other is back to clean so I'll do all of it now.

While this might sound like a lot of work, it's quick and easy compared to the effort required with a power washer to get it clean in the first place, which is quite time consuming.

Yes that should work, and another patio cleaning trick, again with the bio powder, on a dry day, sprinkle a good amount of the Bio in the patio slabs, and leve it there. After a bout 10 days or so ( maybe even less) see how clean the patio will be, even without using a power washer.
