I've just been scrubbing the grout in between out slate floor tiles yet again and they do look good but will soon be filthy again in a couple of months' time.
I've been using a battery operated brush thing from Lakeland to do the task (like a big electric toothbrush!).
I mop the floor every few days and steam clean it about fortnightly. Does anyone have any tips on keeping the grout clean as it's this that seems to get dirty the quickest. Are there any products out there that I can apply to the grout to protect it without ruining the slate tiles?
