I've tried scrubbing them, which has helped a bit, but am

properly, borrow a hgih pressure spray?, apply some chemical?
Whatever as it is only a small area, it must leave the slabs
looking like the remainder of the patio, otherwise swmbo will
continue to moan
Sort of a nuclear option, but I used Ferrous Sulphate to make mine /all/
brown.Â* I prefer them like that.Â* I did that after I failed to find a
way to get the stains off.
Another option is to stand a large pot or urn on the stain and just hide it.
