Rust on bathroom radiators can be eliminated in minutes using a common household product, according to James Chapman, director at Bella Bathrooms. The key is limescale spray, not vinegar, combined with a stainless steel scourer.
Why radiators rust
Bathroom radiators are typically made of steel and plated with chrome to resist rust. However, constant temperature changes and damp conditions cause the chrome coating to break down over time. Moisture then seeps through tiny holes, and rust blooms on the surface, Chapman explained.
Simple removal process
To remove rust, spray the affected area with limescale spray and scrub vigorously with a stainless steel scourer. The acid in the spray breaks down iron oxide, while the scourer lifts the corrosion. After scrubbing, wipe the radiator clean. The rust should disappear, leaving small black specks—the holes in the chrome.
Preventative measures
Since the chrome is compromised, rust will likely return. Chapman advises turning the radiator on to ensure it is bone dry, then spraying it with clear lacquer spray or applying a waxy polish to seal the holes. Regular maintenance is key: repeat the process as soon as rust reappears.
This method offers a quick fix for a common household issue, saving time and money on replacements.
