Tile & Grout Cleaning in Yorba Linda.
Ready on Arrival

Most of the time it cleans back. What reads as "stained grout" is usually years of soap film, body oil, and mineral deposit sitting in a porous surface — pressurized hot-water extraction lifts it. What doesn't clean back: grout that's cracked, missing, or permanently discolored by dye. That's a regrout, and it's a tile trade, not cleaning.

Yes for floors, showers, and anywhere that gets wet. Sealer doesn't make grout stain-proof — it buys you time to wipe a spill before it soaks in, which is the whole game with a porous material. Expect to redo it periodically; frequency depends on traffic and how aggressively the surface gets cleaned.

Because you're cleaning the top of a porous channel. Bleach lightens the color of what's in the grout without removing it, so it looks better for a week and then darkens again. Extraction pulls the soil out. That's the difference, and it's why the result lasts.

A typical bathroom or kitchen floor is a few hours. Surfaces come out damp, not soaked — walkable within a couple of hours, fully dry the same day. If sealer is applied, stay off longer; we'll give you the cure time for the product used.

It depends entirely on the stone. Ceramic and porcelain handle acidic products fine. Marble, travertine, and limestone do not — the same product that clears soap scum will etch them.
