That looks just the thing. Says it won't scratch glass, so
presumably
ok on tile faces? Assuming the matt finish on mine is as hard as
glass?

Just to add, a review says they were great for removing grout residue -
so I've ordered up a set.

Be very interested to know how you get on. I can think of a couple of
possible uses as well.

I've got plenty batteries for the cordless drill so not concerned about
using some water with them.

Only one and that appears to be on it's way out. Though a few decent
dis/recharge cycles would probably do it a world of good.
