Weeeelll... Used the Hg stuff and it didn't attack the limestone. Didn't appear to attack the cement either. The bottle suggests diluting it 1 in 10. I am wondering if I might get away with more. The stone looks a bit better, but chiefly because it's be scrubbed so much, I reckon. I've used a kitched scourer (plastic) on the cement and it shifed it a bit, but basically I don't think this product is having any real effect. It's mostly alcohol, by the way. I'll try it more tomorrow but I don't have much hope for it. Might as well face it, my slabs are a bit mucked. There goes £800, plus scarily expensive fitting. I could have bought a record for that!
