Quick answer
Use a concentrated descaler & tarnish remover to dissolve limescale from metal surfaces, but dilute it correctly and avoid prolonged contact on delicate finishes.
When to use a heavy duty descaler vs. a mild cleaner
Limescale buildup on metal sinks, kettles, or chrome fixtures can be stubborn. Mild household cleaners often fail on thick, baked-on scale. A heavy duty descaler like the Descaler & Tarnish Remover is formulated to rapidly penetrate and remove hard water deposits, rust stains, and tarnish from ferrous metals, aluminium, and chrome. However, it is a strong chemical—always test on an inconspicuous area first, especially on painted or coated surfaces.
Step-by-step: Remove limescale from metal
- 1. Prepare the solution: Dilute the descaler & tarnish remover according to the label instructions. For light limescale, use a 1:10 ratio with water; for heavy buildup, use a 1:5 ratio. Always add descaler to water, not the reverse. Using too strong a concentration can etch aluminium or chrome. Stick to the recommended dilution.
- 2. Apply to the affected area: For kettles or pots, fill with the diluted solution and let it soak for 15–30 minutes. For sinks or chrome fixtures, apply with a sponge or spray bottle, ensuring full coverage on the limescale deposits. Do not let the solution dry on the surface—it may leave streaks or cause dulling.
- 3. Scrub and rinse thoroughly: After soaking, scrub with a non-abrasive sponge or soft brush to lift loosened scale. Rinse thoroughly with clean water. For hard-to-reach areas like kettle spouts, use a bottle brush or run fresh water through repeatedly. Leftover descaler residue can tarnish metal over time. Rinse until no chemical smell remains.
- 4. Neutralize and dry: Wipe the surface with a damp cloth soaked in a mild baking soda solution (1 tsp per liter of water) to neutralize any acid residue. Dry immediately with a soft, lint-free cloth to prevent water spots. Skipping neutralization can leave a dull film on chrome or aluminium.
