Method 1: Lemon Juice and Epsom Salt Method

Both lemon juice and salt have amazing cleaning properties, and together they can help to lift rust stains from your acrylic tub safely and effectively.

Things you’ll need:

  • A microfiber cloth
  • A bottle of lemon juice or 3 whole lemons
  • Epsom salt

1. Pour lemon juice on the affected areas

Start by pouring the lemon juice over the affected spots on the tub. It's also helpful to run the shower for 5 to 10 minutes to help soften up the rust stains so that they will be damp. When they are, the salt will stick to them better.

2. Sprinkle salt on the affected areas

Next, sprinkle the Epsom salt over the stained areas and ensure that all of the stains are completely saturated.

3. Allow the mixture to sit for a few hours

Allow the lemon juice and salt to sit on the rust stains anywhere from three to five hours. It's also helpful to set a timer so that you don't forget to remove the mixture from the tub.

4. Scrub the mixture away

Next, take a microfiber cloth and gently scrub the salt mixture away. If you notice that rust stains are still present on the tub, re-apply the lemon juice and salt and allow them to sit on the stains for another 2 hours. You may need to repeat this once more if the stains are on the larger side.

5. Rinse the tub with warm water

After scrubbing away the mixture, use warm water to rinse off the remaining lemon juice and salt.

Method 2: Baking Soda Method

It's commonly known that baking soda is a great all-natural product to use for combating odors. However, when added to lemon juice, it can be especially effective at removing rust stains safely from your acrylic tub.

Things you’ll need:

  • 2-3 boxes of baking soda
  • A microfiber cloth
  • A cleaning sponge
  • Water

1. Make the baking soda paste

Start by pouring a cup of baking soda into a small bowl. Next, combine it with a half cup of water. Stir the mixture with a spoon until it forms a semi-thick paste. If your tub has a significant number of rust stains, you may need to make a bigger batch of paste.

Find baking soda on Amazon.

2. Apply the paste to the tub

Next, spread the baking soda paste over the tub's affected areas using a clean sponge or microfiber towel. Pay special attention to areas around the drain and the back of the tub faucet and handles.

3. Leave the paste on the stains to soak

The size and age of the rust stains will determine how long the paste should sit. However, it's best to leave it on at least 4 hours for the best results. You can even leave the paste on overnight if needed.

4. Remove the paste with warm water

When it's time to remove the paste, you'll notice that it may be a bit hard. It's helpful to run the shower for five minutes so that the water can soften the paste and make it easier to remove. Then use a wet sponge or rag to go over the paste and wipe it away from the tub.

Be sure to pay special attention to the areas around the tub's hardware when wiping the paste off, as you don't want the baking soda to remain on the metal surfaces for longer needed. If you notice any lingering traces of rust, make another batch of paste and apply it to the stains to repeat the steps again.
