Simple and Natural Method to Erase Rust Stains from Your Bathtub

If your bathtub has been marred by unsightly rust stains, there’s a natural and simple solution that can help you restore its appearance. With just a couple of common ingredients and a little bit of time, you can effectively remove rust stains and make your bathtub look new again. Here’s how to do it:


  • 1 lemon (or lime)
  • 1/4 cup salt


  1. Squeeze Lemon Juice: Begin by cutting the lemon in half and squeezing its juice over the rusty areas in the bathtub. Lemon juice contains natural acids that help break down rust stains.
  2. Apply Salt: After squeezing the lemon juice, cover the rust-stained areas with the 1/4 cup of salt. The salt will work as a gentle abrasive agent to help lift the rust stains.
  3. Allow to Sit: Let the lemon juice and salt mixture sit on the rusty areas for approximately three hours. During this time, the acidity of the lemon juice will interact with the rust and the salt will help in scrubbing away the stains.
  4. Scrub and Clean: After the mixture has had time to work, use a nylon scrubber or a soft cloth to gently scrub the mixture off the rusty areas. As you scrub, you’ll notice that the rust stains start to diminish and lift away.
  5. Rinse Thoroughly: Once you’ve scrubbed the rust stains, rinse the bathtub thoroughly with water to remove any remaining lemon juice and salt residue.

How It Works:

  • Lemon (or Lime) Juice: The natural citric acid in lemon or lime juice acts as a mild acid that can break down rust stains over time.
  • Salt: Salt is a gentle abrasive that aids in scrubbing away rust stains. It also enhances the cleaning process by providing a bit of texture for effective scrubbing.

By combining the acidity of the lemon juice with the abrasiveness of the salt, you create a powerful yet natural solution for removing rust stains from your bathtub.


  • Test a small, inconspicuous area before applying the lemon and salt mixture to the entire tub to ensure it doesn’t cause any damage or discoloration.
  • Lemon juice may cause some surfaces to lighten or bleach slightly, so it’s essential to use caution and to spot-test first.
