This is a very new area of MN to me, because, well, I'm perfect really! Or is it that usually I can't be arsed?
Anyway, I've got a black slate floor, which is reasonably easy to keep clean, but the area around the cooker, has grease marks on it and I've tried all manner of things to get it spit spot, but I've run out of ideas. I've used slate and stone cleaner, soda crystals, Cillit Bang floor cleaner. Is there anything I've missed?
