Get a few bottles of cheap bleach and mix about half a bottle per full watering can. Kills moss and algae just as well for several months.

Sodium Hypochlorite available from any farm shop is great for patio's and Block Paving. 20l is normally around £15. Dilute it 50:50 and it will bring it up like new. Much cheaper.

I did too and in a few days, the moss was dead and a few weeks of rain, largely gone. Sounds like you might have super hero strength moss. Maybe try a higher concentration.

The only way to clean a patio is with a pressure washer I'm afraid folks! (and possibly the high pressure air equivalent - not tried)
Expecting this to clean it is futile. :wink:

Its best to use both to get the patio clean, treatment with this followed by pressure washing even clears black spot lichen after a couple of goes.
Most of these cleaners have the same active ingredient DIMETHYLBENZYL AMMONIUM CHLORIDE just at different concentrations (you can look them up on the HSE website here webcommunities.hse.gov.uk/con…180).
Patio Magic is 7.50% (0.75% to 1.5% after dilution for use depending on heavy or light recommended dilution rates) the other popular version Wet and Forget is 9.9% (1.66% after recommended dilution) and Wilko own brand is 6.25% (0.6% to 1.25%)
