How to Remove Dried Grout From a Tile Surface
- 1). Dampen the dried grout with water, using a sponge. A spray bottle filled with plain water also works well.
- 2). Scrape off the large chunks of dried grout. Use plastic or wood scrapers rather than metal to avoid scratching the tile. A piece of wood works well at removing the large chunks of grout. Apply gentle pressure and scrape away as much of the grout as possible. Discard the large chunks of grout or have a vacuum cleaner handy to suck up the pieces.
- 3). Wipe the area clean with a rag dampened with plain water once all of the large chunks are removed.
- 4). Apply clean water to the tiles' surface using the spray bottle or a clean rag. Moisten a nylon scouring pad in plain water and gently scrub the tiles' surface with the pad. Continue to add water as you are scrubbing the tile. Scrub the tile until you no longer see any grout residue.
- 5). Dry the surface with a soft cloth. Use a blow dryer to go over the tile to ensure that it is completely dry. When the tile is wet, it may look as though all of the grout residue is gone. Dry tile is more likely to show any left-over grout still on the tile
- 6). Fill a bucket with one gallon of warm water and one cup of sugar if there is still a haze on the tile. Pour some of the solution directly onto the effected tiles. For wall tiles, saturate paper towels with the sugar and water solution and stick them to the tile.
- 7). Allow the mixture to sit on the tile for a minimum of two hours. Scrub the tile with a clean nylon scouring pad.
- 8). Rinse the tile with a clean rag and plain water. Allow the tile to dry completely to check for any grout residue. Repeat the application of sugar water if the grout haze is still present. It may take a couple of applications to remove all of the grout and haze from the tile.
