How to Clean Bathroom Tiles and Grout: Porcelain, Ceramic, Mosaic and Natural Stone
28 September 2026 · Tile Touch
Bathroom tiles look after themselves for the most part. The trick is knowing which cleaner suits your surface, because what works on porcelain can damage natural stone. Here is the short version, then the detail for each tile type, plus an FAQ at the end.
The quick answer
For most porcelain and ceramic bathroom tiles, warm water with a little pH-neutral cleaner and a soft cloth or microfibre mop is all you need for a weekly wipe. Rinse and dry to stop water spots. For natural stone, skip anything acidic (no vinegar, no lemon, no generic bathroom spray) and use a cleaner made for stone. For grout, a soft brush and a mild cleaner lift most staining; deeper grime may need a dedicated grout cleaner.
Test any new cleaner on a small hidden area first, especially on stone and on gloss finishes.
Cleaning porcelain tiles
Porcelain is dense and hard-wearing, which makes it forgiving to clean. A matt porcelain floor like the Ryder Grey Limestone Look Matt Porcelain Tile 600x600mm or the Tivoli Mid Grey Ceppo Di Gre Stone Look Porcelain Tile Matt will handle regular mopping with warm water and a pH-neutral cleaner.
Matt surfaces can hold a thin film if you use too much detergent, so keep the dose small and rinse with clean water. Large-format porcelain such as the Lavica Stone Look Italian Porcelain Tile (1000x1500mm) has fewer grout lines, so cleaning is quicker; work in sections and dry as you go to avoid streaks.
For gloss porcelain like the Perla Stingray STI 1, buff dry with a microfibre cloth after washing to keep the shine even and free of water marks.
Textured and grip porcelain
Grip finishes are built for wet areas and outdoor use, so they have more surface texture. The Melrose Silver Grey Limestone Look External Porcelain Tile (600x600mm, 20mm) and the Jordan Stone Look Italian Porcelain Tile in Antracite grip need a stiffer brush now and then, because dirt sits in the texture rather than on top. A soft nylon brush and pH-neutral cleaner clears it; avoid steel wool, which can leave marks.
Cleaning ceramic tiles
Glazed ceramic wall tiles clean much like porcelain. Warm water and a mild cleaner, wiped with a soft cloth, keeps them looking fresh. For a gloss ceramic finger mosaic like the Roseby Mint Green Gloss Kit Kat Finger Mosaic Tile, the glaze does the work; you mainly need to keep on top of soap scum and dry the surface so it stays clear.
Because ceramic is glazed, you rarely need anything harsh. Reach for a soft cloth before a scourer.
Cleaning mosaic tiles
Mosaics look great but come with more grout per square metre, so the grout does most of the ageing. For a gloss mosaic such as the Lucas Mini Black Gloss Hexagon Mosaic, a soft cloth and neutral cleaner handles the tile faces, and a soft brush works the grout lines between the pieces.
Small tiles reward a gentle, regular clean over occasional heavy scrubbing. Rinse well so no cleaner dries in the joints.
Natural stone mosaics need extra care
Not every mosaic is glazed. The Natural Stone Kit Kat Mosaic Carrara Honed is real stone, so it follows the stone rules below: no acidic cleaners, and a stone-safe product only. A honed finish is matt and can dull if you use the wrong cleaner, so treat it gently.
Cleaning natural stone tiles
Natural stone is porous and reacts to acid. That means vinegar, lemon, and many supermarket bathroom sprays can etch the surface, leaving dull patches that no amount of scrubbing removes. Stick to a cleaner labelled safe for natural stone, or plain warm water for everyday wiping.
Stone such as the FRENCH LIMESTONE IVORY in a French pattern, and the honed Carrara mosaic mentioned above, benefit from being sealed. A good sealer slows down staining and makes the weekly clean easier. Reseal when water stops beading on the surface; how often depends on use.
Wipe spills quickly on stone, dry after cleaning, and keep abrasive pads away from honed and polished finishes.
How to clean bathroom grout
Grout is cement-based on most walls and floors, so it holds dirt and can discolour over time. For general grime, a soft brush (an old toothbrush is fine for tight lines) with a mild cleaner lifts most of it. Work along the joint, then rinse.
For heavier staining, a dedicated grout cleaner does more than scrubbing harder. Follow the product directions and rinse thoroughly. Be careful near natural stone: many grout cleaners are acidic and can damage stone tiles, so protect the tile faces or choose a stone-safe option.
A grout sealer, applied once grout is clean and dry, helps keep it looking good for longer.
Simple habits that keep tiles looking good
- Squeegee or wipe shower walls after use to cut down soap scum and water marks, especially on gloss tiles.
- Run the exhaust fan or open a window to reduce moisture, which slows mould in grout.
- Keep a soft cloth handy and do a quick weekly wipe rather than waiting for build-up.
- Rinse cleaners off fully so residue does not attract more dirt.

Frequently asked questions
Can I use vinegar to clean bathroom tiles?
On glazed porcelain and ceramic, diluted vinegar is generally fine for occasional use, though a pH-neutral cleaner is gentler. Never use vinegar or any acid on natural stone such as limestone or honed marble mosaics, because it etches and dulls the surface. When in doubt, choose a neutral cleaner.
How do I keep grout from going dark or mouldy?
Reduce moisture by using the exhaust fan and wiping surfaces dry, since mould needs damp to grow. Clean grout regularly with a soft brush and mild cleaner rather than waiting for build-up. Sealing clean, dry grout adds a layer of protection and makes future cleaning easier.
What cleaner is safe for natural stone tiles?
Use plain warm water for daily wiping and a cleaner labelled safe for natural stone for a deeper clean. Avoid acidic and abrasive products, which damage porous stone and honed finishes. Sealing the stone also helps resist staining.
How often should I clean bathroom tiles?
A quick wipe of shower walls after use and a proper clean once a week suits most bathrooms. Floors benefit from regular mopping with a neutral cleaner. Little and often beats occasional heavy scrubbing, which is harder on both tiles and grout.
