How to Remove Stains from an Acrylic Bathtub

Acrylic bathtubs are known for their sleek appearance and durability. However, like all bathroom fixtures, they can acquire stains from various sources such as water minerals, soap scum, and even mold or mildew. While acrylic tubs are resistant to many traditional staining agents, they aren’t immune to them. The good news is that with the right approach, you can restore your acrylic bathtub’s shine and luster.

Removing stains from an acrylic bathtub requires gentle, non-abrasive methods. Utilize a mild dish soap solution, a baking soda paste, or a vinegar mixture to effectively cleanse the tub. Avoid harsh chemicals like bleach or ammonia, and regularly rinse and dry the tub after use to prevent stain accumulation.

Let’s take a closer look at these methods of cleaning stains from an acrylic bathtub.

Remove Stains from an Acrylic Bathtub with Baking Soda Paste

Baking soda, a common household item, serves as an effective cleaning agent for tougher stains on acrylic bathtubs due to its mild abrasive nature.

  1. Gather your materials: baking soda, water, a bowl, and a soft cloth or sponge.
  2. In the bowl, combine equal parts of baking soda and water to create a consistent paste.
  3. Spread the paste over the stained area using the cloth or sponge.
  4. Allow the paste to settle on the stain for about 10-15 minutes.
  5. Using gentle pressure, scrub the area with the cloth or sponge.
  6. For more persistent stains, you can let the paste sit a bit longer, checking every few minutes.
  7. Once the stain is removed, rinse the area with clean water to ensure all baking soda residue is gone.
  8. Use a different soft cloth to pat the bathtub dry, ensuring no moisture remains.

Remove Stains from an Acrylic Bathtub with Vinegar Solution

Vinegar’s natural acidic properties make it an excellent choice for dissolving mineral deposits and tackling hard water stains on acrylic bathtubs.

  1. Prepare a mixture by combining equal parts of white vinegar and warm water in a spray bottle.
  2. Shake the bottle gently to ensure the mixture is blended well.
  3. Spray a generous amount of the solution onto the stained area, covering it completely.
  4. Let the vinegar solution sit and work on the stain for about 15-20 minutes.
  5. With a soft cloth or sponge, gently wipe away the loosened stains.
  6. If some stains remain stubborn, reapply the solution and give it a few more minutes.
  7. After achieving the desired result, rinse the area thoroughly using clean water to wash away any residual vinegar.
  8. Pat the bathtub surface dry with a clean towel, making sure no water spots form.
