Picture this: you’ve just cleaned your bathroom and you’re looking at your handwork. You’ve cleaned the tub, washed the tile floors and wiped down the mirror. You’re proud, but somehow your bathroom still doesn’t look quite clean. Why is that? Probably because you didn’t get to the grout cleaning.
What is Grout?
Grout is the hard material that fills the joints (grooves between tiles). It prevents the joints from collecting dust, dirt, grease, and liquids. Residential grout is most commonly of the cementitious (sanded or unsanded) or epoxy type. Epoxy grout is more expensive and difficult to install, but is much more resistant to chemicals, water penetration, and staining. It is also easier to clean.

Why do I Need to Clean it?
Grout comes in an infinite variety of colors and varies from very light to very dark. Regardless of the color, grout does get dirty like everything else in yours house, and over time the appearance can change drastically. If your grout is a cement product, stains may be absorbed into the grout through microscopic pores in the surface, which is where sealing comes in.
Sealers, whether clear or colored, penetrating or coating, help prevent staining by filling the pores with a water-repellant material.
How is Grout Cleaned?
For residential projects, where high-pressure cleaning may not be practical, we have found that there is no substitute for applying a cleaning agent and scrubbing. The choice of cleaners depends upon the chemistry of the contaminants and the degree of staining. We use a wet vac with a squeegee wand to extract the dirty cleaner, then triple rinse and extract the rinsate with the wet vac. This process cleans the tile as well as the grout.
For commercial projects with large open areas, we often use our propane-fire steam pressure washer and a wet vac to clean the tile and grout rapidly.
