Cleaning Acrylic Bathtubs - Frequently Asked Questions

Acrylic tubs have become a go-to choice for modern bathrooms. Known for their glossy finish, lightweight build, and heat-retention properties, these bathtubs blend style with practicality. But unlike cast iron or porcelain, acrylic requires careful handling. Using the wrong cleaner or tool can result in scratches, dullness, or even permanent damage.

Learning how to clean an acrylic tub correctly helps preserve its appearance and function for years to come. This expert guide provides step-by-step instructions, recommended products, and professional tips grounded in real-world experience, ensuring your tub stays flawless.

This guide covers everything from managing routine upkeep to tackling hard water stains. Each method is designed to protect the integrity of your bathtub while delivering spotless results. Proper care isn't optional; it's essential for high-end tubs like those from AquaticaUSA .

What Is an Acrylic Tub and Why Does It Need Special Care

Acrylic tubs are made from vacuum-formed sheets of acrylic, reinforced with fiberglass for strength and durability. Their smooth, non-porous surface makes them resistant to mold and mildew buildup and relatively easy to clean. However, their soft surface also means they’re more susceptible to scratches and chemical damage.

Unlike enamel or porcelain, acrylic doesn't tolerate abrasives. A single cleaning session with the wrong product or tool can dull the finish. That’s why using a non abrasive bathtub cleaner and soft cleaning cloth is essential.

Acrylic vs Fiberglass Bathtub

While both materials are lightweight and affordable, acrylic offers better durability and resistance to stains. Fiberglass tubs can develop cracks and dullness faster due to their porous nature. Acrylic, on the other hand, retains a polished look for much longer—if cleaned correctly.

Why Acrylic Requires Special Cleaning

Most commercial bathroom cleaners contain bleach, ammonia, or acetone—harsh chemicals that can degrade the acrylic finish. Even tools like scouring pads and rough sponges can leave permanent scratches. By using only acrylic tub cleaner or DIY solutions like vinegar and baking soda, you maintain the surface without risking damage.

When investing in a premium acrylic bathtub from AquaticaUSA , proper cleaning isn’t just about hygiene—it’s about protecting your investment.

Best Way to Clean an Acrylic Tub: Step-by-Step

Keeping an acrylic tub in pristine condition comes down to consistency and technique. With the right tools and products, you can prevent buildup, protect the surface, and maintain the tub’s original shine. Here’s a detailed breakdown of the best way to clean acrylic tubs—whether you're doing a quick daily wipe or a deep monthly clean.

Daily Cleaning Routine

Performing quick daily maintenance can significantly reduce the need for aggressive scrubbing later.

Rinse the Tub After Each Use: Use warm water to rinse away soap residue, body oils, and bath products. This prevents grime from hardening and staining the surface.
Wipe with a Soft Cloth or Sponge: A microfiber cloth or non-scratch sponge is ideal. This removes residue while being gentle on the tub’s finish.
Spray a Daily Cleaner: Use an acrylic-safe daily shower spray. Products like Method Daily Shower Cleaner or a homemade vinegar-water mix (50/50 ratio) help prevent soap scum.
Check the Drain and Corners: Hair and product buildup often collect around the drain and in tight corners. A quick wipe helps prevent future clogs or stains.

Weekly Gentle Clean

Once a week, take 10–15 minutes to give your tub a more thorough clean.

Prepare Your Materials: You’ll need:
- Acrylic tub cleaner or a mix of dish soap and warm water
- Soft sponge or microfiber cloth
- Spray bottle
- Warm water for rinsing
Apply the Cleaner: Spray your chosen cleaner across the entire tub surface. Let it sit for 5–10 minutes to loosen buildup.
Wipe and Rinse: Gently scrub using a non-abrasive sponge. Focus on areas around the faucet, base, and backrest where product residue accumulates.
Dry the Surface: Use a clean microfiber towel to dry the tub. This prevents water spots and helps maintain the glossy finish.

Monthly Deep-Cleaning Protocol

Even with consistent care, a deep clean is necessary to handle soap scum, mineral stains, and hard-to-reach buildup.

Rinse the Tub Thoroughly: Use warm water to remove any loose particles and pre-wet the surface.
Use a DIY or Store-Bought Cleaner: Apply either:
- A commercial acrylic-safe tub cleaner (such as Biovert or Green Works), or
- A DIY paste made from baking soda and dish soap or hydrogen peroxide.
Let the Cleaner Sit: Allow the cleaner to rest on the surface for 10–15 minutes to break down grime.
Gently Scrub the Tub: Use a soft-bristle brush or sponge. Never use scouring pads, steel wool, or rough cloths.
Focus on Problem Areas: Pay special attention to the corners, drain, and areas under fixtures. For tight spaces, use an old toothbrush.
Rinse Thoroughly: Rinse with warm water until all residue is gone. Any leftover cleaner can cause dullness.
Dry Completely: Buff the surface with a microfiber towel to avoid spotting.

Tip: If you’re wondering how to clean acrylic bathtub without scratching, always test your cleaner on a small, hidden area first. Stick to non abrasive bathtub cleaner options to protect the tub’s finish.

Safe Homemade Options to Clean Acrylic Bathtubs

When it comes to what to clean an acrylic tub with, not all bathroom cleaners are suitable. Harsh chemicals and abrasive ingredients can cause discoloration, etching, and surface degradation. The key to keeping your acrylic tub clean and glossy is using products specifically designed to be gentle and effective. Below are the safest options for maintaining your tub—whether you're buying off the shelf or mixing up a homemade solution.

DIY cleaning solutions are perfect for those who want an eco-friendly approach or need a quick fix using common household items.

White Vinegar and Warm Water (50/50 Mix)
- Best for: Soap scum, water stains
- Spray directly on the tub surface, let sit for 10–15 minutes, and wipe with a soft sponge.
- Avoid using vinegar on sealed caulk or stone trims.
Baking Soda Paste (Baking Soda + Water or Dish Soap)
- Best for: Gentle abrasion for stuck-on grime
- Apply the paste, let sit for 10 minutes, and scrub gently.
- Rinse thoroughly to avoid residue.
Hydrogen Peroxide + Baking Soda
- Best for: Tough stains
- Make a paste, apply it to the stained area, leave for 30–60 minutes, then wipe away and rinse.
Cream of Tartar + Vinegar
- Best for: Deep yellowing or mineral deposits
- Forms a non-abrasive polish that’s safe for acrylic surfaces.

These alternatives offer flexibility and avoid the use of harsh chemicals. Just remember, while baking soda is safe in paste form, it should not be used dry or in large quantities to avoid micro-scratches.

Tools to Use

Equally important as the cleaner itself is the tool you use to apply it. Below is a list of safe tools:

Microfiber cloths: Non-scratch and highly absorbent
Soft sponges: Avoid colored scrubbing pads unless labeled safe for non-stick surfaces
Soft-bristle brushes: Useful for corners and grout lines
Old toothbrush: Perfect for tight spaces like around jets or drains
Spray bottles: Ideal for homemade solutions
Rubber gloves: Always wear gloves to protect your hands, especially when using vinegar or peroxide

Using the correct combination of tools and products makes it easy to clean acrylic tubs without scratching and maintain the finish for years.

Avoid These Mistakes When Cleaning Acrylic Tubs

While acrylic tubs are celebrated for their sleek appearance and ease of maintenance, they’re also delicate when exposed to the wrong tools or chemicals. Missteps in your cleaning routine can lead to irreversible damage—scratches, discoloration, dull patches, or even cracks. Here's what not to use on acrylic tubs and the common mistakes that can cost you.

Do Not Use Harsh Chemicals

Using heavy-duty chemicals might seem like a quick way to deal with stains, but they can permanently damage the acrylic finish. Products that contain bleach, ammonia, acetone, or caustic acids can break down the surface, causing fading and brittleness.

Avoid the following:

Bleach-based cleaners
Ammonia sprays
Nail polish remover (acetone)
Drain openers left near the surface
Paint thinners or solvents

If you're unsure whether a cleaner is acrylic-safe, check the label. Most reputable brands will clearly indicate if their product is safe for use on acrylic.

Avoid Abrasive Tools

When figuring out what to use to scrub a bathtub, stick to soft, non-abrasive materials. Even if a stain looks stubborn, do not reach for rough pads or steel wool.

Avoid these tools:

Steel wool
Scouring pads (especially green or metal ones)
Magic erasers (they are micro-abrasive)
Hard-bristled brushes
Powdered cleansers (too gritty)

A good-quality microfiber cloth, soft sponge, or non-scratch scrub pad is the safest way to clean an acrylic tub without damaging the surface.

Don't Mix Cleaning Products

Combining products—especially vinegar and bleach or ammonia and bleach—can create toxic fumes. Even if you're using natural ingredients like vinegar and baking soda, avoid mixing them with store-bought cleaners unless you’re certain they’re compatible.

Tip: Always rinse the tub thoroughly between cleaner changes and never use multiple products in one session unless directed by a manufacturer.

Avoid Letting Cleaners Sit Too Long

While it’s useful to let cleaners “dwell” for 10–15 minutes, leaving them on for hours (or overnight) can damage the surface—especially if they’re acidic or contain active ingredients. This applies to vinegar, hydrogen peroxide, and even certain eco-cleaners. Time and exposure matter.

Don’t Use Hot Tools or Water That’s Too Hot

Filling your acrylic tub with boiling water might seem like a good disinfecting strategy, but extreme heat can warp the surface or weaken seams over time. Stick with warm water, not scalding, for rinsing and cleaning.

Common Myths to Ignore

Myth: “A good scrub with steel wool will get the grime off faster.”
Reality: It’ll leave permanent scratches and void warranties on high-end tubs like those from AquaticaUSA .
Myth: “Bleach will disinfect and brighten my tub.”
Reality: Bleach discolors acrylic and may degrade seals or caulking.
Myth: “All bathroom cleaners are tub-safe.”
Reality: Many are too strong or abrasive for acrylic surfaces.

Avoiding these pitfalls ensures your cleaning routine extends the life of your tub—not shortens it. Up next: How to Remove Stains from Acrylic Tubs, including expert methods for handling water spots, mold, and rust.

How to Remove Stains from Acrylic Tubs

Stains on an acrylic tub can come from a variety of sources—hard water minerals, soap scum, mold, mildew, and even rust. While acrylic is resistant to discoloration, stains can still form over time if not cleaned regularly. The good news is that most stains are removable with the right methods and tools, without compromising the tub's finish. Here's how to get stains out of an acrylic tub safely and effectively.

Water Spots and Hard Water Stains

Hard water deposits are one of the most common issues in bathrooms, especially in areas with high mineral content.

What You’ll Need:

White vinegar
Paper towels
Baking soda
Soft sponge
Microfiber cloth

Steps:

Soak paper towels in vinegar and place them over the stained areas.
Let them sit for 1–2 hours to break down the calcium buildup.
Remove the towels and apply a baking soda paste (baking soda + a few drops of water).
Gently scrub the surface with a soft sponge.
Rinse thoroughly with warm water and dry with a microfiber cloth.

Tip: Do not let vinegar sit on caulk or grout for long periods, as it may weaken the seal.

Soap Scum

Soap scum builds up over time and leaves a filmy residue that dulls the tub's surface.

Recommended Products:

Dishwashing liquid (like Dawn®)
Warm water
Soft sponge

Steps:

Mix a few drops of dish soap with warm water in a spray bottle.
Spray generously over the affected areas.
Let it sit for 10–15 minutes.
Scrub gently in a circular motion with a sponge.
Rinse and dry.

Alternatively, use Green Works® Bathroom Cleaner or Biovert for a commercial option that’s safe for acrylic tubs.

Mold and Mildew

Mold in tubs usually appears in corners or around the drain where moisture lingers.

What You’ll Need:

Baking soda
White vinegar
Spray bottle
Soft sponge

Steps:

Sprinkle baking soda over the moldy areas.
Spray with a 50/50 vinegar and water solution.
Let the solution bubble and sit for 15–20 minutes.
Gently scrub with a sponge.
Rinse and dry thoroughly.

For prevention, rinse and wipe down the tub after each use to eliminate lingering moisture.

Rust & Mineral Stains

Rust marks often come from metal shaving razors or plumbing fixtures.

What You’ll Need:

Borax powder
White vinegar
Soft sponge

Steps:

Mix borax with vinegar to create a thick cleaning paste.
Apply the paste to the rust-stained areas.
Let it sit for 20–30 minutes.
Scrub gently and rinse thoroughly.
Dry the area completely.

This solution works well without damaging the tub’s surface and is safer than commercial rust removers that may contain harsh acids.

If you're wondering how to clean a plastic tub, the steps are nearly identical, but acrylic tubs are more resistant to deep staining and discoloration. However, plastic tubs tend to be softer and may scratch more easily, so always opt for ultra-gentle tools regardless of material.

By addressing each type of stain using the correct method, you not only restore your acrylic tub’s appearance, you also extend its lifespan.

How to Make a Dull Acrylic Bathtub Shine Again

Over time, acrylic bathtubs can lose their original luster. This dullness is usually caused by mineral buildup, product residue, or micro-scratches from improper cleaning tools. Restoring the shine isn’t just about appearance—it also helps protect the surface from future staining and damage. Here’s the best way to clean an acrylic bathtub and restore that like-new shine.

Step 1: Deep Clean the Surface

Before polishing, start with a thorough clean to remove all soap scum, grime, and residue.

Use a non abrasive bathtub cleaner or a mix of dish soap and warm water.
Apply using a soft sponge, scrub gently, and rinse completely.
Dry with a microfiber cloth to avoid streaks or water spots.

Step 2: Use a Gentle Polish

Acrylic-safe polishing compounds are available to help restore gloss. Look for products labeled “plastic polish” or “acrylic polish.”

How to Apply:

Apply a small amount of polish to a clean, dry microfiber cloth.
Rub in small circular motions across the surface.
Let dry to a haze (if required by the product).
Buff with a fresh microfiber towel until the tub shines.

Step 3: DIY Shine-Boosting Methods (Safe Alternatives)

For those preferring DIY options, these natural methods can enhance shine:

Baking Soda + Vinegar Final Rinse: Sprinkle baking soda on the surface and spray with a 50/50 vinegar solution. Let it fizz for a few minutes, rinse thoroughly, and dry.
Lemon Juice Spray: Mix lemon juice with water in a spray bottle. After cleaning, spray the surface, let sit for a few minutes, then wipe and dry. The citric acid helps dissolve any dulling residue and leaves a mild scent.

Note: Do not use oil-based products like baby oil or furniture polish—they can make the tub dangerously slippery and leave a film that's hard to remove.

Step 4: Maintain the Gloss

Once you’ve restored the shine, keep it going by:

Drying the tub after each use to prevent water spots.
Avoid abrasive cleaners or scrubbers that can create micro-scratches.
Use a daily acrylic-safe spray cleaner to maintain cleanliness.

Shine restoration is an easy final step in your overall acrylic bathtub cleaning routine. With regular care, your tub can maintain its smooth, glossy finish for years—making every bath feel like a luxury experience.
