Why seal the grout
Grout is porous. It soaks up water, grease and dirt. A sealer after the clean slows new stains, so routine mopping works.

How are commercial ceramic tile and grout cleaned and sealed?
We test one patch, then machine scrub the tile and grout, pull the dirty water out and rinse. When the grout is clean we can seal it, so new stains sit on top where routine cleaning reaches them. Ceramic, porcelain and quarry tile all qualify.

Tile and grout specs
| Item | Spec |
|---|---|
| Machines | This work calls for floor machines or rotary scrubbers, hand tools for grout lines, and wet vacuum or wet extraction pickup. We set the method after we see your floor. |
| Grit or pad sequence | Pad or brush chosen by tile surface; textured quarry tile gets a stiffer brush than smooth ceramic |
| Chemistry/finish | Cleaner matched to soil: degreaser for kitchens, neutral cleaner for lobbies; penetrating grout sealer |
| Dust or slip control | Wet process; double rinse; wet-floor signs until dry. Tile for level wet interiors is rated at wet DCOF 0.42 or higher |
| Return to service | Set for each project, per the sealer maker's data sheet |
| Work hours | Nights, weekends or when the restroom or kitchen is closed |

A tile and grout job, room by room
Test a patch
We clean one small area to see how deep the soil goes and whether the grout takes a sealer.
Block off the room
Restrooms, kitchens and lobbies close one at a time. We book the hours with your manager.
Scrub tile and grout
Machines and hand tools work the tile face and the grout lines.
Extract and rinse
We pull the dirty water out and rinse twice so no film stays behind.
Seal, check, hand back
The grout is sealed if the scope calls for it. We inspect the room before it reopens.

Signs Your Tile Needs More Than a Mop
Check the grout first. Then look for these:
- Grout lines a shade or two darker than when the tile was new
- Dirty water left in the grout after mopping
- A film that makes the tile feel slick when wet
- Dark spots by sinks, fryers or machines
- Odor in restrooms that comes back after cleaning

Grout, Restaurant Tile and Reglazing
Restaurant kitchens and restrooms
Grease and food settle in grout lines and textured tile. We clean around your opening hours. See restaurant floor care.
Cleaning or reglazing?
Cleaning removes dirt and buildup from the tile you have. Reglazing puts a new coating on it. We tell you which one your floor needs.

Tile and grout questions
Should grout be sealed after cleaning?
Usually yes on cementitious grout. It is porous and takes in water, grease and dirt. A penetrating sealer slows that, so routine cleaning keeps it clean. Epoxy grout does not need it. We test your grout first.
How often should commercial grout be cleaned?
Kitchens and restrooms often need it more than offices. The test is simple: if grout is a shade darker than new tile, or mop water turns grey, it is time. We set the schedule after a test patch.
Do you clean restaurant kitchen tile and grease?
Yes. Grease needs a degreaser, a rinse and often a rougher brush on quarry tile. We schedule around your closing hours. The method calls for a double rinse and a dry floor before reopening.
Is cleaning the same as reglazing tile?
No. Cleaning removes dirt and buildup from the tile you have. Reglazing puts a new coating on it. We tell you which one your floor needs.
Does cleaning change the slip rating of tile?
Cleaning removes film that makes tile slick, so floors often feel safer. The tile's own rating comes from its maker. ANSI A137.1 sets wet DCOF 0.42 or higher for level interior tile that gets wet.
