To remove rust from clothes, never use chlorine bleach, which can make it worse. Treat the stain with lemon juice and salt on white cotton and leave it in daylight, or use a rust remover made for fabric, following the directions. Rinse thoroughly, wash as the label allows and check before drying. Test first and ask a professional for delicate items.
Orange-brown rust stains appear from all sorts of places: a rusty zip or button, a metal washing line, a hairgrip left in the machine or even a leaky radiator. They look alarming, and they are often stubborn, because rust is a mineral stain that sits in the fibres and is not removed by ordinary detergent.
The good news is that most rust stains respond to the right products, and the first rule is knowing what not to use. This guide explains how rust stains form, what works on white and coloured fabrics and when to ask for help.
Why rust stains are different
Rust is iron oxide, a mineral stain that bonds to fabric. Ordinary detergent does not dissolve it, and the wrong treatment can make it permanent. In particular, chlorine bleach reacts with rust and can turn the stain a darker, more permanent orange. The right approach uses a mild acid or a purpose-made rust remover.
What not to do
- Do not use chlorine bleach, which can set rust stains.
- Do not tumble dry or iron the stain, which sets it.
- Do not leave the stain for weeks.
- Do not mix rust remover with other products, since some are strongly acidic.
- Do not use strong acids on delicate fabrics.
Lemon juice and salt method for white cotton
- Lay the stained area flat over a clean cloth.
- Sprinkle the stain with salt, then squeeze fresh lemon juice onto it to saturate it.
- Leave the garment in sunlight, or a bright place, for an hour or two, keeping the stain damp with more juice.
- Rinse thoroughly with cool water.
- Wash the garment as the label allows and check the stain before drying.
This gentle home method works best on fresh rust stains on white or colourfast cotton. Test on a hidden area first, because lemon juice can lighten colours.
Using a rust remover
Rust removers made for fabric, often containing oxalic or similar acids, are more effective on stubborn and older stains. Follow the directions exactly, wear gloves, work in a ventilated place, test on a hidden area and rinse thoroughly afterwards. Use them on white and colourfast fabrics only, and never mix them with bleach.
Coloured and delicate fabrics
On coloured fabrics, acids and rust removers can lighten the colour, so test carefully. On silk, wool and other delicates, avoid home treatment with acids, and ask a professional, who can choose a safe approach. See our guide to delicate fabrics explained, and for general first aid see our stain removal guide.
Rust on white shirts, towels and sheets
Rust often appears on white laundry that has been washed with a metal item or hung on a rusty line. Treat it as soon as you spot it, before it goes through another wash, and wash whites separately from metal items. An oxygen-based stain remover can brighten the fabric afterwards, but it does not remove the rust itself.
Finding and stopping the source
- Check the drum of the washing machine for rust and loose metal items.
- Empty pockets of hairgrips, coins and keys.
- Replace or cover rusty zips, buttons and metal fixings.
- Check washing lines and clothes airers, and replace rusty ones.
- Check for leaks from radiators and pipes if the stains are on soft furnishings.
Rust on carpets, upholstery and other textiles
Rust can also stain carpets, rugs and upholstery. Blot first and treat with a rust remover suitable for the fabric, testing on a hidden area. See our guides to cleaning a carpet and cleaning upholstery, and our rug cleaning and upholstery cleaning services for deeper stains.
When to ask a professional
If the stain is old, large, on a delicate or valuable item, or has not shifted after one or two careful attempts, ask a professional. Tell them what you have tried, and do not wash or dry the garment first.
