Choose a descaler for the surface, not just for the white deposit. A product that removes limescale can also damage stone, plating or seals. Read the surface maker's care instructions and the cleaner label, use the specified contact time, then rinse and dry as directed.
Why surface compatibility matters
Many limescale removers are acidic. The Natural Stone Institute warns that acids can damage calcareous stone and recommends suitable neutral stone cleaners. Keep vinegar, lemon juice and acidic descalers away from marble and limestone; don't assume other stone or sealants will tolerate them either.
A hidden-area test is an extra precaution, not permission to use a product that the manufacturer prohibits.
Match the method to the item
| Item | A sensible starting point | Avoid |
|---|---|---|
| Tap | The maker's approved cleaner, applied as directed with a soft cloth | Prolonged acid wraps, abrasive pads and treating an unknown finish |
| Shower head | The manufacturer's descaling instructions; detach only if designed to be removed | Assuming all plated heads can be soaked |
| Shower glass | A product compatible with the glass and any protective coating | Letting acid run onto stone trays, grout or metal trim |
| Kettle | The manual's approved descaler and rinse procedure | Submerging the electrical base or mixing cleaning products |
| Toilet | A suitable toilet descaler, following its label | Adding descaler where bleach or another product is still present |
| Natural stone | A stone-safe neutral cleaner and specialist advice for scale | Vinegar, lemon or a general acidic bathroom cleaner |
| Washing machine | The model's maintenance instructions | Improvised acid treatments that may affect seals or components |
Taps and shower fittings
Wipe loose residue away first. Check the finish: chrome, brushed metal, coloured coatings and plated brass can have different care requirements. Apply only the permitted cleaner for the permitted time, rinse and dry with a soft cloth.
Do not wrap a tap in acid and cling film for an hour just because a general guide suggests it. If a compatible product does not remove a thick deposit within its instructed use, ask the maker or a specialist rather than increasing the strength or dwell time yourself.
Shower screens
Protect surrounding surfaces. Use a compatible cleaner on a small section, follow the stated contact time and rinse thoroughly. A squeegee after each shower reduces the water left to dry on the glass. Follow care instructions for coated glass; harsh abrasives can damage it.
Kettles and appliances
Unplug the kettle before manual cleaning and keep its base dry. Follow the model's descaling and rinse instructions, including any fresh-water boiling cycles. The appropriate frequency depends on the appliance, use and local water.
Leave boiler treatment and gas-appliance work to qualified professionals. In a rented home, report persistent appliance or plumbing problems to the landlord.
Find your Sussex water information
Your water supplier and sewerage provider may differ. Supplier boundaries do not follow town or postcode-district names perfectly. Check your bill or use the official supplier finder, then enter your full postcode on the supplier's own site.
We do not publish a single hardness figure for Brighton, Hove or another town. Use the current result for your address and check the units before comparing figures. The Drinking Water Inspectorate explains hardness.
Limescale at the end of a tenancy
Compare the check-out condition with the check-in record. Record existing scale when you move in, and keep messages about faults or surfaces that cannot safely be cleaned. Ordinary cleaning and a repair to a damaged fitting are different tasks.
Use the move-out checklist to put bathroom cleaning in the wider plan. For difficult build-up across several rooms, ask about a deep clean; describe the surfaces and condition so we can confirm what is appropriate.
