How to Remove Rust With Salt

Rust is one of the most difficult stains to remove.

Using a combination of salt and lemon juice to remove rust is a safe, environmentally-friendly and effective way to get rid of a rust stain, whether on a surface or on an article of clothing.

Mix salt and lemon juice in a bowl. Add enough lemon juice so that you create a thick paste.

Spread the paste onto the rusty surface with a dry cloth and let it sit for half an hour. If you are removing rust from an article of clothing, lay the clothing on a flat surface and spread the mixture on the stain.

Rinse the area with cool water. If the rust stain is still there, apply a fresh coat of salt mixture. You may need to repeat these steps for several hours before the rust is gone.

Things You Will Need

  • Salt (enough to completely cover the stain)
  • Lemon juice (enough to completely cover the stain)
  • Bowl
  • Spoon
  • Cloth


  • Lime juice can be used in place of lemon juice.
  • If you are removing rust from a tougher surface, you can scrape it away with a brush or scrubber.
  • Sometimes you will need to leave the mixture on the rusty surface overnight or even longer.
  • Do not use this method on a delicate piece of clothing, as the lemon juice could damage it.
