Patio maintanace advice

Hi guys!


Just pressure washer my patio (i belive it is Bradstone Old Riven) which is aprrox 3 years old.

I used a reasonable pressure washer but no chemicals at all, just water.

On the whole it has come up suprisingly well but there are one or two areas that I cannot get clean. The patches are green in colour.

Any advise on what to try on these stubbon areas and also is there such a thing as a patio sealant chemical that you could recommend to furure protect the patio.


Many Thanks

Chris

use an algae remover. you can using a paving sealer when its all ceaned and dried up. test the remover and sealer on a small area first to make sure it doesnt react badly on the paving

Try thick bleach.
