How do I get the excess mortar off this black limestone?
I have tried using this product as directed for the "first wash". And scrubbing with a stiff scrubbing brush.
If I scrape it with a knife once softened up I have better luck. So wondering about a wire brush, but on the small test area I tried out before it scratched.
I'm nervous about pressure washing in case I damage the grout - and as expected most of the residue is near the grout lines.
Any tips much appreciated.
Cheers.
(yes, I know I should have used cleaner and pressure washed it before the grout went down)
