If you notice stains after scrubbing, repeat the process until the rust stains are gone.


Turn off the water supply to your toilet, and then flush the remaining water in the bowl. After that, directly pour Coca-Cola into the toilet bowl and allow it to sit overnight. The soda has an acid that helps eat away at the rust stains. Turn the water supply back on and flush your toilet. And then, use your toilet brush to scrub the remaining stains.

White Vinegar and Water

Make a solution of an equal amount of water and white vinegar. Then pour the solution on a cloth and scrub the rust stains with the soaked cloth. You can also pour the solution into a sprayer bottle rather than use a cloth. If you have stubborn rust stains, you can use more vinegar than water in your cleaning solution. Let the solution soak into the stain before you rinse it.

Borax Powder and Lemon Juice

The combination of Borax powder and lemon juice generally removes rust stains. Mix a cup of lemon juice and Borax powder and wait until the solution turns to paste. Put the paste onto the rust stain and leave it for a few hours. Then remove the paste, and the rust stain should be gone.

How to Prevent Rust Stains in Your Toilet Bowl

  • Clean regularly. When you clean your toilet at least once a week, it will prevent the accumulation of iron and other deposits from forming rust stains.
  • Add a water softener or iron filter. Water purification systems and filters can eliminate the problem at the source by removing iron deposits in the water to prevent future rust stains. Some water softener salts are even specially formulated to fight rust.
  • Upgrade your plumbing system. Older homes usually have iron pipes, and rust deposits will continue to form due to the pipe breakdown until you upgrade the old pipes.
