Question

I am having an issue with a ceramic tile floor. It has many years’ build-up of a residue that I believe is graphite. I have tried to strip the floor without any luck. I have even tried tile and grout cleaner. Any suggestions?


Answer

Graphite is a greasy form of carbon. It would seem that a degreaser with adequate dwell time would loosen it, so it can be removed with wet vacuum. Have you tried steam, or a hot water pressure wash tool on a truck mount? Before you do anything, test the above process in a small 6 inch area before proceeding.
