Once the grout has set, which takes about three hours, you will probably see a thin white film on your tiles. This is called grout haze and it will need to be removed. As long as you have not waited longer than three hours, you should be able to clean any remaining haze with a clean sponge barely dampened with water.
Furthermore, what to use to clean tiles after grouting?
Also question is, how long should grout dry before removing haze?
Floor grout, in general, usually dries completely after 24 hours, although humidity and other factors can extend this drying time to 48+ hours. Grout haze can sometimes be simply buffed out with a dry towel or cheesecloth, if done immediately within the first 48 hours.
Will grout haze wear off?
Grout haze is a semi-white film left on the surface of the tile after grouting. Even if you have diligently wiped down the surface with a wet sponge, the haze will remain and will not come off until you take special measures. Ordinary cleaning methods will not remove it.
Will baking soda remove grout haze?
If for some reason the grout haze does not come clean or you waited just a little too long, you can use a solution of ½ cup of vinegar, ½ cup of ammonia, 1 cup baking soda and 2 quarts of water or pick up a commercial haze cleaner at the store.
