What's the correct way to go about cleaning these? The customer was under the impression they couldn't be pressure washed - I'll be honest :
It's been a long time since I've done any pressure washing (too busy with everything else!) and I've been fortunate enough to just have newer slabs in the past with little/no black spots so haven't used hypo before (which I'm guessing is needed here).
However, keen to learn how to do these properly!
