To clean grout off wall tiles, wet the tiles with water, use a wooden scraper to chip off the grout, rinse and scrub with a nylon scouring pad. It is important not to use a metal scraper to remove the grout because it may damage the tile.
When doing a tile job, sometimes excess grout is left to dry on the tiles. Because it takes a few days, or weeks, for grout to harden, the sooner the job is done the better.
- Gather the supplies Wooden scrapers made out of oak work best to chip off hardened grout. Use a power saw to make sure the scrapers have a square cut. A nylon scrubbing pad and a soft sponge or cloth are also necessary.
- Dampen the tile with water and begin scraping Start in a small area to see how difficult the process will be. Wet the area with water; it will act as a lubricant and may make the grout removal easier. Use the wooden scraper to chip away at the hardened pieces of grout.
- Clean and scrub Rinse the area with clean water once the chipping is complete. Use the nylon scrubber to scour the area. This removes any small pieces of grout that may be left on the tile. Rinse with clean water and dry with a soft, clean cloth.
