I have large patio ( c. 300 sq. meters) built with crazy paved natural yorkstone.
It has become black stained over the years and even jet washing will not remove the black stain. ( the Green algae etc is no problem)
I have tried the products advertised in the newspapers which make claims to revive everything to its original sate but this is just BS.
Do you have a product recommendation?
Is sandbalsting a sensible option?
