Kitchen Design/Remodeling/Grout on face of glass tile


I installed a mosaic tile backsplash and the polyblend grout dried quicker than expected on the face of the tiles. Is there a safe way to soften the grout without damaging the tiles or the mastic underneath?  I've spent hours trying to remove it without much success.  I really don't want to remove the tile and start over, but that my be the shorter path.

You will have to use an acid cleaner. You can start by getting Sulfamic Acid powder from a hardware store or box store. Mix it  as strong as package instructs. Then rinse well. If this mild acid is not strong enough, you may need to use a stronger acid. Please refer to the stain removal chart on our website at Look at the tabs under main picture.

Best of luck.
