Rust on bathroom radiators can be a persistent problem, but experts say it can be tackled with a common household product. James Chapman, director at Bella Bathrooms, explains that chrome-plated steel radiators are prone to rust when the protective coating breaks down due to moisture and temperature changes.
Chapman recommends using limescale spray and a stainless steel scourer to remove rust. 'Rust is basically iron oxide and acids will break it down,' he said. 'Spray the radiator, which will start to kill the rust, and then give it a really good scrub.'
After scrubbing, wipe the radiator dry. The rust should be gone, leaving small black specks that indicate holes in the chrome. To prevent recurrence, Chapman advises applying clear lacquer spray or waxy polish to seal the holes. 'Make sure your radiator is on because it needs to be bone dry,' he added.
Regular treatment is key: as soon as rust reappears, repeat the process. This simple method can keep your bathroom radiator rust-free with minimal effort.
