How to Clean Tile & Grout

Tile is durable, but grout is porous and absorbs dirt over time. Here's how to clean both—and restore discolored grout to its original brightness.

Know Your Tile Type

Different tiles require different cleaning approaches. Using the wrong cleaner can damage or dull certain materials:

Ceramic
Most cleaners OK
Porcelain
Most cleaners OK
Natural Stone
No acidic cleaners
Marble
No vinegar/lemon
Slate
pH-neutral only
Travertine
No acidic cleaners
Acidic Cleaners Damage Natural Stone
Vinegar, lemon juice, and many commercial cleaners are acidic and will etch marble, travertine, and limestone—causing permanent dull spots. Always use pH-neutral cleaners on natural stone.

Routine Tile Cleaning

Daily: Dry Cleaning

  • Sweep or dust mop to remove grit (prevents scratching when wet mopping)
  • Vacuum using hard floor setting if preferred
  • Wipe up spills promptly—especially on grout

Weekly: Wet Mopping

  1. Sweep first—Always remove loose dirt before wet mopping
  2. Mix cleaning solution—For ceramic/porcelain: warm water + mild detergent. For stone: pH-neutral stone cleaner only
  3. Mop in sections—Don't flood the floor; work in manageable areas
  4. Rinse with clean water—Residue buildup dulls tiles over time
  5. Dry if needed—Stone tiles especially benefit from drying to prevent water spots
Microfiber Mop Tip
Microfiber mops clean tile better than string mops. They pick up dirt rather than pushing it around, rinse cleaner, and don't leave excess water on the floor. Have two pads: one for cleaning, one for drying.

Deep Cleaning Grout

Grout is porous and absorbs dirt, mold, and mildew. Even with regular cleaning, it darkens over time and needs periodic deep cleaning.

The Baking Soda Method (Mild)

Good for light discoloration on any grout type:

  1. Make a paste: 3 parts baking soda to 1 part water
  2. Apply paste to grout lines with old toothbrush or grout brush
  3. Let sit 5-10 minutes
  4. Scrub with stiff brush in circular motions
  5. Rinse thoroughly with clean water
  6. Wipe dry

Hydrogen Peroxide Method (Stronger)

For moderate grout staining—safe for most grout but test first on colored grout:

  1. Mix baking soda paste as above
  2. Add a few drops of hydrogen peroxide (3% solution)
  3. Apply to grout, let sit 10-15 minutes
  4. Scrub with grout brush
  5. Rinse thoroughly

Oxygen Bleach Method (Heavy Staining)

For seriously discolored grout—safe for colored grout unlike chlorine bleach:

  • Use OxiClean or similar oxygen bleach powder
  • Mix according to package directions
  • Apply to grout, let sit 15-30 minutes
  • Scrub and rinse thoroughly
Chlorine Bleach Cautions
While effective, chlorine bleach can discolor colored grout, damage nearby fabrics, and releases harsh fumes. If you use it, dilute heavily (1:10 with water), ventilate well, wear gloves, and never mix with other cleaners. Oxygen bleach is a safer alternative.

Steam Cleaning

Steam cleaners work well on tile and grout:

  • Safe for ceramic and porcelain tile
  • Kills mold and bacteria without chemicals
  • Use the grout brush attachment for grout lines
  • Avoid steam on unsealed natural stone (moisture can penetrate)

DIY vs. Commercial Cleaners

Good DIY Options

  • Baking soda + water paste: Safe for all tile types, gentle but effective
  • Dish soap + warm water: Good for regular mopping
  • Hydrogen peroxide: Brightens grout, kills mold

Effective Commercial Products

  • Zep Grout Cleaner: Strong, works on stubborn stains
  • Bar Keeper's Friend: Good for rust stains on ceramic
  • Stone Tech Stone & Tile Cleaner: pH-neutral for natural stone
  • Black Diamond Stoneworks: Safe for all tile types

Skip the Vinegar on Tile

While vinegar is often recommended, it has drawbacks:

  • Damages natural stone (etching)
  • Can break down grout sealant over time
  • Leaves residue if not rinsed thoroughly
  • Better alternatives exist for tile specifically

Sealing & Prevention

Why Seal Grout?

Grout is porous like a sponge. Sealing creates a barrier that:

  • Prevents stains from penetrating
  • Makes cleaning easier
  • Inhibits mold and mildew growth
  • Extends time between deep cleanings

How to Seal Grout

  1. Clean thoroughly first—Sealer locks in whatever is there
  2. Let grout dry completely—Wait 24-48 hours after deep cleaning
  3. Apply sealer—Use applicator bottle to apply along grout lines
  4. Wipe excess off tile—Don't let sealer dry on tile surface
  5. Let cure—Usually 24 hours before getting wet
Reseal Annually
Grout sealant wears off over time. In high-moisture areas like bathrooms, reseal every 6-12 months. For floors, once a year is usually sufficient. Test by dropping water on grout—if it soaks in instead of beading, it's time to reseal.
Bathroom Tile in Humid Climates
Long Island's coastal humidity creates ideal conditions for bathroom mold. Run exhaust fans during and 20 minutes after showers. Consider a dehumidifier in bathrooms without windows. Weekly cleaning prevents mold from establishing.

Frequently Asked Questions

Can I use bleach on grout?

Chlorine bleach works but can discolor colored grout and releases harsh fumes. Oxygen bleach (OxiClean) is effective and safer. On white grout with good ventilation, diluted chlorine bleach can be used occasionally, but it's not the best regular cleaning method.

Why is my grout still dirty after cleaning?

Either the staining has penetrated too deep (old, unsealed grout), you're seeing mold under the surface, or the grout is permanently discolored. Sometimes professional cleaning with high-pressure extraction is needed. In severe cases, grout may need removal and replacement.

How do I clean grout without scrubbing?

Spray-on grout cleaners can reduce scrubbing. Apply, let sit 15-30 minutes, then rinse. Steam cleaners also reduce physical scrubbing. But for significant staining, some scrubbing is usually necessary.

Is professional grout cleaning worth it?

For heavily stained grout, yes. Professional services use high-powered extraction and can often restore grout that DIY methods can't touch. They can also reseal properly afterward. Worth considering every 2-3 years for maintenance.

Can I change grout color?

Yes. Grout colorants/stains can refresh and change grout color. Clean thoroughly, apply colorant with brush, wipe excess from tile, let dry. It's tedious but effective. Consider professional application for large areas.
