Using bleach to clear moss off tarmac - anybody actually tried it?

...and here is a pic, taken just now, of some moss that was sprayed with vinegar on Saturday afternoon:

Was that neat or diluted?

Straight out of the bottle! Well, via the sprayer, actually, but not diluted!

How about a gentle power wash and a stiff brush

Don't/won't have a power washer, and the objective is to minimise the amount of effort needed with the yard brush on account of my shoulder problems.  If I can make the stuff dead first, the brushing's got to be easier.  I hope ...

Just back to report that urine worked after spraying twice, 48 hours apart, as did 50% malt vinegar (5% acidity).  So the choice is down to your preferred residual whiff - urinal or chip shop.

This has been a great thread, keep up the good work @Si_Clist.

Maybe you have more money than I do.

Soda crystals.
Sprinkle on before rain is due or dampen slightly after sprinkling on.
About 99p for a 1kg bag.

I wonder if Baking Soda and vinegar would work?

Does a treat on drains and steel.

I'm sulking because when I had the slab path professionally laid it went from 20yrs of dirt to almost like new. He said just brush with a stiff brush - doesn't work for me.

I did use a wire brush on the pavement edge outside my last house - and a hoe - and vinegar. Yes the trick was to kill it then brush it up and it was easier.
