How to Clean Porcelain Tile Floors Like a Pro

To clean porcelain tile floors, sweep or vacuum first, then mop with warm water and a gentle cleaner — for glazed tile, ¼ cup white vinegar per gallon of water works well; for unglazed tile, use mild dish soap instead, since acid can damage unglazed porcelain. Rinse with plain water, dry with a microfiber cloth, and buff glazed tile with cheesecloth to prevent streaks. Avoid bleach, ammonia, abrasive cleaners, and metal brushes, all of which discolor or scratch the tile and grout. Here’s the full method for glazed, unglazed, and shower tile.

What makes porcelain tile special

• It’s denser and less porous than ceramic, so it’s very durable.
• It comes in hundreds of colors and designs.
• It’s compatible with radiant floor heating.

There are two types, and the difference matters for cleaning: through-bodied (unglazed) and glazed. Glazed tile has a hard, shiny, sealed finish; unglazed (through-bodied) tile is colored all the way through but more porous — which is why it needs gentler, non-acidic cleaning and sealing.

Products and supplies

Avoid:

• Harsh or abrasive cleaners
• Metal brushes
• Anything that could stain the tile or grout
• Soap-based products on glazed tile (they leave scum)
• Bleach, ammonia, or chlorine (they can discolor tile)

How to clean glazed porcelain tile without streaks

Glazed tile’s shine shows streaks, so technique matters.

Step 1: Sweep or vacuum, then go over with a dry mop.
Step 2: Mop with warm water to lift remaining dirt.
Step 3: Mix a gallon of warm water with ¼ cup white vinegar and mop.
Step 4: Work stubborn spots with a soft brush and the same solution.
Step 5: Rinse by mopping again with plain water.
Step 6: Dry with a towel or microfiber cloth.
Step 7: Buff with dry cheesecloth to remove streaks and water spots.

How to clean unglazed porcelain tile

Unglazed tile is more porous, so skip the vinegar — acid can etch it. Use dish soap instead.

Step 1: Sweep with a soft broom to avoid scratching.
Step 2: Mop with warm water and mild dish soap, using a soft brush on stubborn dirt.
Step 3: For grout, scrub with a soft toothbrush and a 1:1 baking-soda-and-water paste.
Step 4: Rinse by mopping with warm water.
Step 5: Dry with a towel or microfiber cloth.
Step 6: Apply a sealant to protect the porous surface (about one cup of sealant to three cups of water).

How to clean porcelain shower tile

Step 1: Rinse with warm water to remove hair and loose grime.
Step 2: Mix two cups warm water with two teaspoons white vinegar (glazed tile) in a spray bottle.
Step 3: Apply and work stubborn spots with a soft brush.
Step 4: Rinse with warm water.
Step 5: Dry with a towel or microfiber cloth.

Buff glazed tile with cheesecloth to remove water spots. For stained grout, a steam cleaner works well before you clean the tile. (On unglazed shower tile, use dish soap rather than vinegar.)

Tips to keep tile cleaner longer

• Sweep or vacuum weekly to stop dirt building up.
• Wipe spills promptly to avoid stains.
• Never use bleach, chlorine, or ammonia — they discolor tile.
• Avoid abrasive products that scratch the surface.
• Use only soft-bristle brushes, never metal, on tile or grout.
• Don’t use anything acidic — including vinegar — on unglazed tile.
• Seal unglazed tile to protect it.
• Put a doormat at entrances and encourage wiping feet or removing shoes.

Conclusion

Porcelain tile is easy to keep beautiful once you know the key distinction: vinegar for glazed, dish soap for unglazed, and gentle tools and no harsh chemicals for both. Sweep regularly, wipe spills fast, dry well, and seal unglazed tile, and your floors will stay gorgeous for years.
