How to Remove Rust Stains
Rust stains appear when iron-containing metal contacts wet fabric, leaving an orange-brown mark. Unlike many stains, rust requires an acid-based treatment — lemon juice and salt or a commercial rust remover work best. Regular laundry detergent alone will not remove rust.
Affected Materials
Step-by-Step Removal
- 1
Apply lemon juice
Squeeze fresh lemon juice directly onto the rust stain, saturating the area completely.
- 2
Add salt
Sprinkle table salt over the lemon juice on the stain. The combination creates a gentle abrasive acid treatment.
- 3
Place in sunlight
If possible, lay the garment in direct sunlight with the lemon-salt mixture on it. The sun accelerates the chemical reaction.
- 4
Wait and rinse
Let the treatment work for 1 to 2 hours, then rinse thoroughly with cold water.
- 5
Wash normally
Launder as usual. Repeat the treatment if any rust color remains before drying.
What Not to Do
- ✗Do not use chlorine bleach on rust stains — bleach reacts with iron and makes the stain worse.
- ✗Do not put rust-stained items in the dryer before treatment.
- ✗Do not use this method on dry-clean-only fabrics without testing first.
- ✗Do not skip the rinse — lemon juice can weaken fabric if left too long.
