Tile and Grout Cleaning in Roseville
Grout turns dark because it is porous and soaks up dirt. Cleaning pulls it out, and sealing keeps it from soaking back in.
Why Grout Turns Black
Grout is a porous mix. Foot traffic, cooking splatter, soap and damp air work dirt and mildew into it, and ordinary mopping pushes grime into the grout lines instead of lifting it out.
Cleaning Methods Compared
Hand Scrub
A brush and cleaner. Low cost, slow, and best for small areas like a shower.
Steam
Hot steam loosens dirt and needs less chemical. Results depend on how deep the dirt is.
Machine and Pressure
Rotary tools or high-pressure rinsing reach deeper dirt over large floors and are usually done by professionals.
Whatever method is used, clean grout gets dirty faster if it is not sealed afterward. See grout sealing.
What It Costs
Inch Calculator says cleaning is about $0.50 to $4.00 per square foot, though a summary box on the same page lists $3 to $5, so the page is not consistent. It also says many services require a minimum fee of $100 to $150. See the full cost table.
Common Questions
Why is my grout turning dark?
Grout is porous, so dirt, grease and mildew work into it and mopping alone does not lift them out.

Published ranges run about $0.50 to $4.00 per square foot, with a minimum of $100 to $150 common.
Should I seal grout after cleaning?
A sealer helps keep new dirt and moisture out. See the grout sealing guide.
Can very dark grout come back to its original color?
Often much lighter, but stains deep in the grout may not fully lift.
