How to Clean Acrylic Bathtub

Acrylic bathtubs are lightweight, affordable, and retain heat well — but they scratch easily and require gentler cleaning than porcelain or cast iron. Using the wrong products or abrasive tools can permanently dull or scratch the surface. Here's how to keep your acrylic tub clean and looking new.

What Makes Acrylic Different

Acrylic is a plastic material with a smooth, non-porous surface that resists staining but is vulnerable to:

• Scratches from abrasive cleaners or scrubbing pads
• Dulling from harsh chemicals (bleach, acetone, ammonia)
• Yellowing from UV exposure and certain cleaning products over time
• Crazing (fine surface cracks) from solvent-based cleaners

What NOT to Use on Acrylic Tubs

• ❌ Abrasive scrubbing pads or steel wool
• ❌ Undiluted bleach
• ❌ Acetone or nail polish remover
• ❌ Ammonia-based cleaners
• ❌ Abrasive powder cleansers (like Comet)
• ❌ Pumice stones

What You'll Need

• Dish soap or mild bathroom cleaner
• White vinegar
• Baking soda
• Soft microfiber cloths or non-scratch sponge
• Rubber gloves
• Spray bottle

Recommended: white vinegar, baking soda, microfiber cloths, rubber gloves, and a spray bottle.

Regular Cleaning: Weekly Maintenance

1. Rinse the tub with warm water.
2. Apply a small amount of dish soap to a damp microfiber cloth.
3. Wipe down all surfaces using gentle circular motions.
4. Rinse thoroughly with warm water.
5. Dry with a clean microfiber cloth to prevent water spots.

Dish soap is gentle enough for acrylic and effective at removing body oil and soap residue.

Removing Soap Scum from Acrylic

1. Fill a spray bottle with equal parts white vinegar and water.
2. Spray the affected areas and let sit for 10–15 minutes.
3. Wipe with a soft microfiber cloth — no scrubbing needed for light soap scum.
4. Rinse with warm water and dry.

Removing Stains from Acrylic

1. Make a paste with baking soda and water.
2. Apply to the stained area with a soft cloth.
3. Let sit for 5–10 minutes.
4. Gently rub in circular motions with the cloth — baking soda is mild enough for acrylic.
5. Rinse thoroughly.

Removing Hard Water Stains from Acrylic

1. Soak a microfiber cloth in undiluted white vinegar.
2. Lay it over the hard water stain and let sit for 20–30 minutes.
3. Wipe away — the mineral deposits should dissolve without scrubbing.
4. Rinse and dry.

Deep Cleaning Acrylic Tub (Monthly)

1. Sprinkle baking soda over the entire wet tub surface.
2. Spray white vinegar over the baking soda.
3. Let the fizzing reaction work for 15–20 minutes.
4. Wipe gently with a microfiber cloth.
5. Rinse thoroughly with warm water and dry.

Restoring a Yellowed Acrylic Tub

If your acrylic tub has yellowed over time:

1. Fill the tub with warm water and add 2 cups of white vinegar.
2. Let soak for 1–2 hours.
3. Drain and wipe with a baking soda paste.
4. Rinse thoroughly.

For severe yellowing, a dedicated acrylic tub restorer product may be needed. Avoid bleach — it can worsen yellowing on acrylic.

Preventing Damage to Acrylic Tubs

• Always use soft cloths or non-scratch sponges — never abrasive pads
• Rinse the tub after every use to prevent soap scum buildup
• Dry after cleaning to prevent water spots and mineral deposits
• Use a bath mat with suction cups rather than a rough-bottomed mat that can scratch the surface
• Avoid leaving hair dye, nail polish remover, or strong chemicals in contact with the surface

Frequently Asked Questions

Can I use bleach on an acrylic bathtub?

Avoid undiluted bleach. Diluted bleach (1 tablespoon per quart of water) can be used occasionally for disinfection, but regular use will dull and yellow the acrylic surface over time.

Can I use a Magic Eraser on acrylic?

Use with caution. Magic Erasers are mildly abrasive and can dull the acrylic finish with repeated use. Test in a hidden area first and use very light pressure.

How do I remove scratches from an acrylic tub?

Minor scratches can be buffed out with a non-abrasive acrylic polish or car wax applied with a soft cloth. Deep scratches may require professional refinishing.

Final Thoughts

Acrylic tubs are easy to maintain when you use the right products. Stick to soft cloths, dish soap, white vinegar, and baking soda for regular cleaning — and avoid anything abrasive or solvent-based. A weekly gentle clean and a monthly baking soda-vinegar treatment will keep your acrylic tub looking bright and scratch-free for years.
