Introduction
Clean tiles transform a room. Dirty or stained tiles age a space faster than almost anything else. The good news is that regular tile cleaning keeps most tiled surfaces in top condition for years. The bad news is that the wrong cleaning products destroy tiles, grout, and sealers permanently. This guide covers what works and what to avoid for every common tile type found in Australian homes. Follow these methods to keep your tiles looking fresh without causing damage.
General Tile Cleaning Rules
Start with the simplest approach. Warm water and a microfibre cloth or mop handle most everyday tile cleaning. For a deeper clean, add a small amount of pH-neutral tile cleaner to the water. Avoid anything highly acidic or alkaline unless you know your tile type allows it. Always sweep or vacuum loose dirt and grit before mopping. Grit acts like sandpaper under a mop and scratches tile surfaces over time. This matters most with polished porcelain tiles and natural stone tiles.
How to Clean Porcelain and Ceramic Tiles
Porcelain and ceramic tiles are the most forgiving tile types. They resist most household cleaners. Warm water with a splash of white vinegar works well for routine cleaning. For stubborn stains, a paste of baking soda and water applied with a soft brush lifts most marks without scratching. What to avoid on porcelain and ceramic tiles: steel wool, abrasive scouring pads, and bleach-based cleaners used regularly. Occasional bleach use on white grout is fine, but daily bleach exposure breaks down grout sealers and weakens grout joints.
How to Clean Natural Stone Tiles (Marble, Travertine, Bluestone, Granite)
Natural stone is porous and reactive. This is the tile type where most cleaning mistakes happen and cause expensive damage. Never use vinegar, lemon juice, or any acidic cleaner on marble or travertine tiles. Acid etches the surface and leaves dull spots that are expensive to restore professionally. Even leaving a lemon slice on a marble benchtop for a few minutes causes visible, permanent etching. Use a stone-specific pH-neutral cleaner for all natural stone tiles. Products like Lithofin MN Easy Clean or Aqua Mix are widely available at Bunnings and tile supply stores across Melbourne. Clean spills quickly, especially wine, coffee, and tomato-based sauces. Bluestone tiles and granite tiles are more durable but still benefit from pH-neutral cleaners. Avoid anything containing ammonia or bleach on any natural stone surface.
How to Clean Terracotta Tiles
Terracotta tiles are highly porous and absorb liquids fast. They require regular sealing (every 1 to 2 years depending on foot traffic). Clean terracotta tiles with warm water and a pH-neutral cleaner only. Never use acid-based products. A well-sealed terracotta floor repels most stains, but an unsealed terracotta floor absorbs stains permanently.
How to Clean Tile Grout
Grout collects dirt and mould faster than the tiles themselves. For routine grout cleaning, a stiff nylon brush with warm soapy water does the job. For mould in shower grout, spray a 1:1 mix of white vinegar and water, let it sit for 10 minutes, then scrub with a grout brush. For heavy grout staining, a grout-specific cleaner with oxygen bleach (sodium percarbonate) lifts deep stains without damaging the grout. Apply, wait 15 minutes, and scrub. Rinse with clean water. Avoid chlorine bleach on coloured grout. Chlorine bleach fades grout colour permanently. If your grout is beyond what cleaning restores, read our guide on when to re-grout for next steps.
Tile Cleaning Products That Cause Damage
| Product | Damage Caused | Tiles Affected |
|---|---|---|
| Vinegar / Lemon Juice | Etches and dulls the surface permanently | Marble, travertine, limestone |
| Steel Wool / Scouring Pads | Permanent scratches on polished surfaces | All polished tiles, porcelain, marble |
| Bleach (regular daily use) | Breaks down grout sealers, weakens grout | All grouted tile surfaces |
| Ammonia-Based Cleaners | Discolours stone, strips sealers | Natural stone, terracotta tiles |
| Wax-Based Floor Polish | Builds up sticky yellow residue | All floor tiles |
Weekly Tile Cleaning Routine
For most tiled areas in your home, this routine keeps tiles and grout looking fresh: Sweep or vacuum twice per week to remove grit. Mop once per week with warm water and a pH-neutral cleaner. Wipe shower walls with a squeegee after each use to prevent soap scum buildup. Deep clean grout once per month. Reseal natural stone tiles and terracotta tiles annually.
When to Call a Professional Tiler
When stains or damage go beyond what cleaning fixes, professional help is the next step. Cracked grout, persistent mould that returns within days, chipped tiles, and tiles lifting from the substrate all require professional attention.

FAQ
Q: What is the best way to clean porcelain tiles?
A: Sweep first to remove grit, then mop with warm water and a pH-neutral tile cleaner. For stubborn stains, use a baking soda and water paste with a soft brush. Avoid steel wool and abrasive pads.
Q: Can I use vinegar to clean tiles?
A: Vinegar is safe on porcelain and ceramic tiles. Never use vinegar on natural stone tiles like marble, travertine, or limestone. Vinegar is acidic and permanently etches and dulls natural stone surfaces.
Q: How do I remove mould from tile grout?
A: Spray a 1:1 mix of white vinegar and water on the mouldy grout. Let it sit for 10 minutes, then scrub with a stiff nylon brush. For persistent mould, use an oxygen bleach (sodium percarbonate) grout cleaner. If mould returns within days, the grout needs replacing.
Q: How often should I seal natural stone tiles?
A: Seal marble and travertine tiles every 6 to 12 months. Seal granite tiles every 1 to 2 years. Seal terracotta tiles every 1 to 2 years. High-traffic areas and wet zones need more frequent resealing.
