I recently paid to have ceramic tile installed. The workers used a
grout sealer that apparently has left a film on the tile surface. The
reason I think the film was caused by the sealer is that it can be seen
at an angle and covers either side of each grout line about an inch or
My question: How can the film be removed? So far, we have tried a
commericial product from a tile manufacturer (Armstrong) and a
vinegar-and-water mix. Neither worked AT ALL.
Suggestions will be GREATLY appreciated!
