Removing moss between pavers

[Marnhullman]

I need to clean moss from the jointing compound between a large area of paving which is comprised of various sized slabs so there aren't long straight runs of joints.

I've removed some moss with a stiff brush but it would be hard work to do it all manually. I'm thinking about an electric joint cleaner but the illustrations of use I've seen show them being used where there's no jointing compound between the slabs. I'm concerned the machine may be too powerful and may rip out the jointing compound.

The machines appear to come with a wire and a nylon brush so maybe the nylon wouldn't be too aggressive?

I do have a pressure washer I could use but when I used it at a previous property it ripped out the mortar, which, to be fair, was poorly applied to a pretty rubbish paving job. The paving I have now has jointing compound which appears to be much stronger than mortar?

Has anyone experience of using one of these machines on jointing compound between slabs?

Any advice appreciated.

moss remover (ferrous sulphate) mixed as a solution, sprinkled on, wait a few days then gently brush it all off, you may need to use some brick acid to clean off the iron stain if that doesnt go in the few days after treatment

moss remover (ferrous sulphate)

is for use on lawns and should not be used on paving as it will stain them.

For hard surfaces like patios then something containing benzalkonium chloride (BAC) is the appropriate product. That includes Patio Magic (which I have used) and Wet & Forget (which I haven't). The branded products are c. 7% BAC and you dilute it down to c. 2%. I bought 5L of 50% which I use on my (very tatty) front yard, pictures at

NB Any moss killer will kill the moss, that is all, it will not remove the dead moss. In a lawn the dead moss is normally raked out but if left will eventually decay. On a patio the dead moss will need to be removed. Hopefully it will be relatively loose and so can be brushed out.
