Remove metal marks on tiles

[Pewit]

While drilling a hole in a kitchen unit, I accidently left some metal marks from the drill chuck on the raised un-glazed pattern of the tiles.

Ansy suggestions as to how I can remove them?

I have seen rust remover suggested but in my experience this tends to leave behind un-oxidised metal.

Thanks

Paul

you could try a green pot scouring pad, these are very good for removing all kinds of stains without damaging the base material. Another alternative would be a lightly abrasive cream/polish like brasso or "solvol autsol" available from any good car shop. Best of luck.
