Cover the entire piece of stone with water and let it soak for several minutes. The water will help lubricate the area as you remove the haze so you don’t scratch the stone.
Scrub away the haze with plastic, scratch-free abrasive pads.
Pour more water on the area as it dries out.
Rinse the area with water and wipe it dry with towels.
Dilute the grout haze remover to the least concentrated solution according to the manufacturer’s instructions. Only use grout haze remover intended for use on natural stone.
Dip a sponge into the remover and wring out as much of it as possible.
Rub the sponge over the natural stone. Let it sit according to the manufacturer’s instructions. Some may not call for any sitting time.
Rinse the sponge, wring it out and rub over the rest of the stone. If any grout haze remains, continue to the next step.
Dilute the grout haze remover to a more concentrated solution according to the manufacturer’s instructions. Repeat the application process with this solution until no grout haze remains.
