How to sustainably clean ceramic tile and grout

Ceramic tile is one of the most durable, low-maintenance surfaces in any home—especially when it’s cleaned with the right products and techniques. Over the years, I’ve learned that tile care isn’t complicated. It’s about consistency, gentle methods, and giving extra attention to grout (the part that actually gets dirty).
Below, you’ll find a practical guide to keeping your ceramic tile and grout looking its best—using only safe, sustainable cleaning products.
Eco-friendly ceramic care at a glance
Safe:
Baking soda
Hydrogen peroxide (white tile grout only)
Plant-based detergents
Steam
Not safe:
Abrasive powders (on grout)
Steel wool, metal brushes
Oil-based cleaners
Ammonia
Acidic cleaners
Key principle:
The grout needs the most attention
Toronto tip:
Hard water deposits can build up fast! Getting into the habit of squeegeeing the shower after use makes a huge difference.
What not to use on ceramic tile
Before we look at what works, here are the products and techniques that cause the most damage:
Scouring powders
While safe for the tile itself, these products contain chemicals that can damage the surrounding grout’s protective sealer—leaving it prone to staining and chemical erosion (etching).
Steel wool and metal brushes
Scratch glaze beyond repair
Leave behind metal particles that rust or stain
Damage grout lines
Acidic cleaners
Similar to scouring powders, these products may be safe for use on the tile itself but can etch the surrounding grout and structurally weaken it.
Ammonia-based products
Fade coloured grout
Can discolour certain tile glazes
Oil-based cleaners
Leave a sticky, dirt-attracting film
Make floors slippery
Are difficult to remove
Common cleaning mistakes
Too much soap
Excessive soap creates a residue that:
Attracts dirt
Looks dull
Requires multiple rinses
Can make floors slippery
Dirty mop water
Reusing dirty water spreads grime across your floor. Rinse your mop and change your bucket water frequently.
Pro tip: Use less product—but clean more often.
Safe, natural cleaning for ceramic tile
Routine floor cleaning (daily/weekly)
Sweep or vacuum to remove loose grit (prevents scratching).
Use a solution of 4L warm water and 2 1/2 tablespoons (37.5 mL) of castile soap.
Mop with a natural-fibre mop.
Mop again with clean water to remove any remaining soap residue
Dry immediately with a lint-free cloth.
For stubborn dirt and stains
Baking soda paste is your friend
Sprinkle baking soda onto the area.
Mist with water to form a paste.
Let sit for 5–10 minutes.
Scrub with a non-metallic natural-fibre brush.
Wipe or mop clean.
Dry thoroughly.
Soap scum on shower tile
Soap scum is stubborn, but heat and natural cleaners can work beautifully.
Steam cleaning
Benefits:
Chemical-free
Great for grout
Ideal for bathrooms with heavy soap scum
Safe for sealed grout
Alternative to steam
I personally use a product that is designed to remove both soap scum and mineral deposits from tile and grout.
Post-shower squeegeeing prevents most soap scum buildup.
Eco-friendly grout cleaning
Grout is porous, fragile, and prone to staining.
Regular grout cleaning:
Mix baking soda and water into a paste.
Apply along grout lines.
Let sit 10–15 minutes.
Scrub with a non-metallic natural-fibre brush.
Rinse thoroughly.
Dry.
For white grout with heavy stains:
Mix hydrogen peroxide with baking soda to form a paste.
Apply to grout lines.
Let sit 10–15 minutes.
Scrub gently.
Rinse well.
Avoid using on coloured grout, as peroxide can lighten it.
What to know about grout sealing
Sealed grout resists stains, lasts longer, and is dramatically easier to clean.
Tile is:
Hard
Glazed
Non-porous
Grout is the opposite:
Porous
Softer
Absorbs stains quickly
Susceptible to mould
Discolours easily
How to test your seal:
Drop water on a grout line.
If it beads → you’re protected.
If it absorbs or darkens → reseal soon.
Tips to preserve grout sealer:
Dry shower walls after each use
Use your bathroom fan during and 20 minutes after showering
Clean spills quickly
Address leaks promptly—water is grout’s worst enemy
Always follow manufacturer guidelines when sealing grout.
Common grout & tile problems
Crazing (fine cracks in the glaze)
Crazing is a network of tiny cracks in the glaze.
Causes:
Age
Temperature fluctuations
Manufacturing flaws
What to do:
Clean gently
Avoid abrasives
Monitor for moisture under tiles
Replace only if water intrusion becomes an issue
Sometimes crazing is simply part of the tile’s character.
Mould and mildew
Natural removal method (white grout only):
Spray 3% hydrogen peroxide on affected grout.
Let sit 10 minutes.
Scrub with a natural-fibre brush.
Rinse.
Dry completely.
I personally use a surface mould solution that’s both eco-friendly and safe for coloured grout.
Mould and mildew prevention:
Run the exhaust fan during and after showers
Seal grout following manufacturer’s recommendations
Fix humidity or water issues quickly
Increase ventilation if possible
If mould returns repeatedly, moisture may be trapped behind the tile—call a professional.
Chipped, cracked, or loose tiles
Small chips: can be filled with natural-tone epoxy
Cracked tiles: should be replaced to prevent water damage
Loose tiles: re-adhere promptly to avoid mould under the surface
Permanently stained grout
Your options:
Grout colourant/paint: lasts 1–3 years
Regrouting: long-term solution
Leave it as a character feature: if it’s hygienically clean, it’s safe to do so
When to call a professional
Stains won’t lift
Mould keeps returning
Tiles are loose, hollow, cracked, or lifting
Grout is crumbling or missing
You need help identifying moisture issues
You simply don’t have time for grout scrubbing (it’s a workout!)
Early professional assessments often prevent far more expensive repairs later.
