St. George sits on some of the hardest water in the state, and that calcium settles into porous grout every time the floor gets wet. Add red dirt off shoes and grease in the kitchen and the lines turn gray or brown long before the tile face shows it. Light grout shows soil first, but dark grout hides hard water film that still needs to come out.
Showers are the other big one in this valley. Soap, body oil, and mineral spray sit in the grout lines all week, and a regular bathroom cleaner cannot reach down into the pores. We flush it with the same truck-mounted system we use on kitchen and entryway floors.
Our IICRC-certified crew is honest about what cleaning will and will not fix. Discoloration from soil, hard water, and soap usually comes out. Permanent dye stains, mildew that has eaten into the grout, and grout that is failing structurally are color-seal or regrout jobs.
