I have moved to a new house and recently when the delivery guys delivered my
washer and dryer, they put them on the ceramic tile and pushed it for a
short distance. Since the plastic legs hadn't been installed, now I discover
that there are some Metal marks left on my ceramic tiles. Is this scratches
deep inside the ceramic? or is it just metal/paint leaving on the surface of
the ceramic? I tried to use detergent to remove it but no luck.. help..
