Black stain on white porcelain, unglazed, unsealed tiles Oct 13, 2008 11:21 AM

Hello. Thanks for reply. We followed the advice you provided. The instructions on the Miracle company Grout & Concrete Film Remover were very similar because of its hydrochloric acid component. We tested this Remover with small quantities at various dilutions on a surplus sample tile. The Remover did not remove the black. What is your reaction to the neutralizer recommended to follow the Remover? In dilute form we recall seeing hydrochloric acid (AKA muriatic acid) listed as a component in a toilet bowl cleaner. We finally had good results with a mildly alkai cleaner and lots of elbow grease. Looking back, the tile retailer should have added sealer to the original purchase of tiles and black grout.

Black stain on white porcelain, unglazed, unsealed tiles Oct 8, 2008 08:52 PM

After laying white porcelain, unglazed and unsealed tiles, we applied a black grout between the tiles. Before it dried the residue on the white tiles as scrubbed off with wet sponges. What remained was a streaky, gray color on each tile. The gray, streaky color could not be removed with wet sponges. We tried a hydrochloric base cleaner Miracle Grout & Concrete Film Remover and had no success. Ed
