Just wondering if bleach is a safe alternative for removing stains in the grout. The staining I am having trouble with is from rain water leaching onto a basement floor. The grout is white and never been sealed.
bleach can remove stains in grout but isn’t recomended. I’ve have seen
sanded grout become brittle and the grout becomes more course. You can try a stripper on low side of ph scale- acid but be careful. The acids cleaners will remove the top layer of the grout, also its very important to seal grout after acid cleaner is used.
Thanks Rick,
Could you explain the risks of using diluted bleach on the grout?Brain
DIY’S and housecleaners use bleach all the time to clean their tile and grout with little success.. As you know once bleach touches carpet,rugs or furniture etc it has a harsh reation. Also I have seen the grout texture deteriorate when cleaned with any mixture of bleach.Rick
Brian,
Not that I would expect any great results with likely inorganics, but did you try any FAE at all…mixed properly? Hit with HSC and extracted?
Just a thought…
Grout is so pourous as it is. I could see how getting stains out would be tough. From the little tile and grout we have done, I noticed that it was next to impossible to clean it out. A lot of people down here tell us that their grout was not sealed or treated and this could be the reason that dirt, grease, spills, etc would stay behing for good. Wish I could tell you more. Bleach is so abrasive to anything.

You might be surprised to find out that grout cannot be sealed at the time of tile installation. Newly installed grout usually needs 72 hours to cure before a sealant can be applied to it. Since sealer is not necessarily a “requirement” of a tile and grout job, contractors will often skip this important step for one, or both, of the follow reasons:
Reason #1: It would require a return trip to the job sight, 3 days or longer from the installation date. This is often difficult for busy contractors.
Reason #2: They would incur additional man hours as well as the material costs associated with the cleaning and sealing the newly installed tile and grout.
