Red Seal Tilesetter Practice Exam

Which method is recommended for cleaning tiles after grouting?

1. Using a dry cloth

2. Using a steam cleaner

3. Using a damp sponge and warm water

4. Using chemical cleaners

The correct answer is: Using a damp sponge and warm water

Using a damp sponge and warm water is recommended for cleaning tiles after grouting because it effectively removes excess grout and haze without damaging the surface of the tiles. This method is gentle enough to avoid scratching or marring the tiles while effectively lifting away any grout residue. Warm water helps to soften the grout, making it easier to wipe away. While a dry cloth may seem convenient, it can actually spread grout residue around rather than removing it, leading to a less effective cleaning process. A steam cleaner can be too aggressive, potentially causing damage to delicate tiles or grout joints due to intense heat and pressure. Chemical cleaners, although they may be effective, can contain harsh substances that might harm the tile or grout, or even leave behind residues that could be detrimental in the long run. Thus, the use of a damp sponge and warm water strikes the best balance between safety and effectiveness for post-grouting tile cleaning.
