when my quarry tile is wet the water beads in only some areas. when the tile is dry it looks blotchy....matt finish vs satin finish (where the sealant still is). I have sanded, stripped, etc. and the remaining sealant will not come off. I scraped with a razor blade and nothing happens. Can I use paste wax to shine up the floor and eliminate the blotchiness? the tile is indoors and I do not want to get into acids.
