How to Get Rid of Rust in a Washing Machine Tub

Quck answer

Rust can accumulate inside the tub of a washing machine over time, causing stains on clothes and potentially damaging the machine. To remove rust from a washing machine tub, follow these steps:

1. Empty the machine and unplug it from the power source.

2. Create a mixture of equal parts baking soda and water to form a paste.

3. Apply the paste to the rusted areas and let it sit for about 15 minutes.

4. Use a scrub brush or sponge to scrub away the rust.

5. Rinse the tub thoroughly with water to remove any remaining residue.

6. Wipe the tub dry with a clean cloth.

7. For persistent rust stains, repeat the process or consider using a rust remover product specifically designed for washing machines.

Regular maintenance, such as wiping the tub dry after each use and avoiding leaving wet clothes inside the machine for extended periods, can help prevent rust from forming in the future.


Rust can appear in unexpected places, including the drum of a washing machine. Like all appliances, washing machines need regular cleaning and maintenance to prevent issues like rust. Discovering rust in the washer’s drum means that your clothes may come out stained after washing. Before using the machine, take steps to remove the rust and ensure clean and ready-to-dry laundry.

Using Lemon Juice or Vinegar for Cleaning

The acidic properties of lemon juice or vinegar make them effective in combating rust buildup. These household products are affordable and require minimal effort for rust removal.

Step 1: Prepare the Washing Machine

Before treating the rust, check the drum for any forgotten clothing items. Small items like socks can easily be overlooked, so make sure to remove everything. Additionally, inspect the drum for any foreign objects that may have accidentally been left or fallen inside the washer.

Step 2: Apply Vinegar or Lemon Juice

Pour 2 cups of lemon juice or distilled white vinegar directly into the drum. Allow the liquid to sit for an hour, giving the acid time to work on the rust.

Step 3: Run a Machine Cycle

Run a regular cycle with the hottest water setting, without adding any clothes. The acidity of the lemon juice or vinegar will work throughout the cycle to remove the rust from the drum.

Other Methods for Treating Rust

If there are stubborn rust spots that were not removed by lemon juice or vinegar, apply WD-40 to those areas and wipe off the excess with a clean cloth. WD-40 is effective in tackling tougher corrosion spots in the tub.

If lemon juice and vinegar are not sufficient, you can try a chemical cleaner like CLR. For front-loading machines, remove all laundry and add 1/2 cup of CLR to the detergent dispenser. Run a normal cycle. For top-loading machines, remove all laundry and start the regular wash cycle. Stop the machine before the tub starts agitating. Add 1/2 cup of CLR to the full tub of water and let the cycle complete. Run an additional cycle without CLR to rinse away any residue.
