Tile and grout cleaning gets the dirt out of the one part of the floor a mop never reaches. Grout is porous cement. Every time you mop, dirty water settles into the grout lines and dries there. After a few years, light grout turns gray or brown, and scrubbing on your knees doesn't seem to change it.
Our tile and grout cleaning uses an alkaline pre-treat that loosens soil and grease, a brush to work it into the grout lines, and then a spinning tool that rinses with hot water at high pressure and vacuums it up in the same pass. The dirty water goes to our truck, not across your floor.
Showers are a different job. In Spanish Fork, shower tile and glass collect hard water scale, the white crust from calcium and magnesium in the water. We use an acidic rinse on ceramic and porcelain to break that down. We do not use acid on natural stone like travertine or marble, because it etches the surface. Stone gets a pH-neutral cleaner.
After cleaning, we can apply a penetrating sealer to the grout so it resists staining. It doesn't make grout waterproof, but spills sit on top long enough to wipe up. Sealer needs a day to cure before heavy traffic.
Tile floors are also common in the basements and bathrooms we dry after water damage. If water got under loose tiles or cracked grout, structural drying comes first and cleaning comes after.
