Rust stain

Rust stains have a metallic, brownish look and often show up around old taps, radiators, or hangers.

Because rust is insoluble in water, it won’t come out with ordinary washing – it needs special treatment.

The key is to use an acidic solution. Mix equal parts lemon juice and salt, apply to the stain, and leave it for 15–30 minutes. If possible, place the garment in sunlight during this time, as warmth helps the reaction. Then rinse thoroughly and wash as usual.

For stubborn marks, a commercial rust remover can be very effective – but always read the garment’s care label first and test on a hidden area. On white clothes, the simple lemon-and-salt method often works especially well.
