Vitreous ceramic is one of the toughest materials in your home: it does not absorb water, odours or stains. Clean it the right way and a toilet will still look new after decades. Clean it the wrong way and you can dull the glaze, damage the seat and ruin the fittings. Here is the routine we recommend.
Weekly cleaning
-
Lift the seat and lid. Clean the bowl with a soft toilet brush and a mild, non-abrasive toilet cleaner. On a rimless WC, one pass reaches the whole bowl.
-
Wipe the outside with a soft cloth and warm water with a little washing-up liquid or a neutral bathroom cleaner. Rinse and dry.
-
Clean the seat separately with mild soap and water. Do not use bleach or strong chemicals on the seat. Keep the lid open while a bowl cleaner is working: the fumes trapped under a closed lid can discolour the seat's finish.
-
Wipe the flush plate with a damp cloth only.
How to remove limescale
Limescale is calcium carbonate left behind by hard water. It dissolves in acid, so the trick is to use a mild acid and give it time to work, instead of a strong acid or scrubbing hard.
-
Lower the water level so the product can reach the stained area. Flush while holding the water supply closed, or push the water out with the brush.
-
Apply citric acid or white vinegar. Dissolve 2–3 tablespoons of citric acid in a litre of hot (not boiling) water, or use neat white vinegar. Pour it over the limescale. For the rim line, lay paper towels soaked in the solution over the deposit.
-
Leave it to work: at least a few hours, ideally overnight for heavy deposits.
-
Brush and flush. Repeat if needed. Thick deposits often need two or three rounds.
Prevention is easier than cure: a weekly splash of vinegar or citric acid solution keeps limescale from building up, especially in hard-water areas.
What to avoid
-
Abrasive powders, steel wool and scouring pads: they scratch the glaze. Scratched glaze holds dirt and stains more easily. This matters even more on matt colour finishes.
-
Pumice stones: often recommended online, but they can scratch if used dry or with pressure. If you use one, keep it wet and only on stubborn deposits at the waterline, never on matt or coloured ceramics.
-
Hydrochloric (muriatic) acid: very effective but hazardous to handle, it gives off harmful fumes and attacks chrome, metal fittings, grout and seals. Not worth the risk.
-
Mixing products: never mix bleach with acid-based cleaners or vinegar. The reaction releases toxic chlorine gas.
Yearly maintenance checklist
- Check that the seat hinges are tight and the soft-close still works (see our soft-close seat guide).
- If the toilet keeps running or refills slowly, the cistern's fill valve may need descaling. See our guide to cisterns and flush plates.
- Check the silicone joint at the base or against the wall, and replace it if it has gone black or come away.

Upgrading?
If your old toilet has a rim full of stains you can never reach, a new rimless WC solves the problem at the root. The Alice Ceramica design WCs are rimless and made in Italy. Read why rimless toilets are easier to clean.
