How to Deep Clean Tile Floors in Commercial Kitchens and Restrooms

Quarry tile in kitchens and ceramic tile in restrooms take a beating from grease, soil and mop water that settles into the grout lines. Regular mopping often makes grout worse, because a string mop just pushes dirty water into the low joints. Deep cleaning takes the right machine.

Why Mopping Falls Short

Grout sits below the tile face, so a flat mop never reaches it. Over time the grout darkens and the floor looks dirty even right after mopping. The fix is mechanical agitation plus recovery of the dirty solution, which is exactly what scrubbing machines do.

The Deep Cleaning Steps

1. Sweep or vacuum to remove loose debris
2. Apply an alkaline degreaser for kitchens or a tile and grout cleaner for restrooms, and let it dwell
3. Agitate with a grout brush on a floor machine or use an auto scrubber with a grit brush
4. Recover the dirty solution with the scrubber or a wet/dry vacuum
5. Rinse with clean water and recover again so no residue dries on the surface

Steam for Heavy Grease and Sanitizing

For greasy kitchen tile, a commercial steam cleaner melts grease out of the grout and sanitizes without heavy chemicals. Steam followed by extraction lifts grime that scrubbing alone leaves behind, which is why many restaurants use both.

Keeping Grout Bright

• Switch from string mops to microfiber or scrubbing, which do not redeposit dirt
• Seal grout after a deep clean so it resists staining
• Clean spills quickly in kitchens before grease sets
• Schedule a deep scrub monthly, more often in heavy grease areas

Restroom Tile Notes

Restroom floors collect urine salts that cause odor and yellowing grout. An acidic restroom cleaner dissolves these deposits, but use it only on tile rated for acid and rinse thoroughly. Deep scrub and extract rather than mop, and the odor problem usually goes away with the residue.
