White grout haze inevitably accumulates on newly installed tiles during the grouting process. Grout haze consists of cement and additives, which harden and increase their bond to tiles over time. The longer grout haze sets on tiles, the tougher it becomes to clean off. Failure to remove grout haze in a timely manner can cause tiles to become permanently marred with white residue. Fortunately, commercial grout haze removers are not required to remove grout haze from tiles; home remedies are just as effective but cost less and do not contain toxic chemicals.
Fill a spray bottle with warm water. Spray the water onto the affected tiles to completely saturate the grout haze.
Fill a plastic bucket with warm water for rinsing purposes.
Scrub the wet tiles with a synthetic fibre scouring pad to remove the grout haze. Frequently dip the scouring pad in the rinsing bucket to prevent reapplying grout particles to the tiles. Clean off as much grout haze as possible.
Examine the tiles for remaining traces of grout haze. If white residue persists, fill a second bucket with one gallon of warm water. Completely dissolve one cup of sugar in the warm water.
Pour the sugar solution over the remaining grout haze. Leave the solution on the haze for two hours.
Scrub off the remaining grout haze with the scouring pad. Periodically rinse the scouring pad with fresh water.
Wipe the clean tiles with paper towels until dry.
Substitute a sharp-edged oak stick for the synthetic fibre scouring pad. Wear leather gloves to prevent getting splinters from the wood.
Abrasive cleaning pads, metal scrapers and wire brushes can scratch tiles.
