Hi K,
We come across this problem a lot, the best thing to use is a combination of Tile Doctor Remove and Go and Nano-tech ultra clean, mixed 50/50 and then applied to the Tiles, left to dwell for a bout 2 hours and then use a wet vac and some water and a deck/ scrubbing brush to help lift the old dirt, sealer, grease etc, anything else that is still stubborn try using a wall paper steamer held down fast for a minute or so, then rinse with water and vac it up.
