How to Clean Acrylic Shower Walls | Simple Ways to Keep Them Shiny & Scratch-Free

Acrylic shower walls are a favorite in many modern bathrooms because they’re affordable, durable, and look great. However, soap scum and hard water stains can build up over time, making them look cloudy or streaked. Using harsh cleaners or rough tools can also scratch or discolor the surface.

The good news is that with the right cleaning methods and some regular care, you can keep your acrylic shower walls clear and scratch-free for years. This guide covers everything you need to know, including safe cleaning solutions and simple maintenance tips.

Why Acrylic Shower Walls Need Special Care

Acrylic is a non-porous plastic material that resists mold and mildew better than tile or grout. However, it’s also more prone to scratches and cloudiness when exposed to harsh chemicals or rough scrubbing.

Common culprits behind dull acrylic include:

• Soap residue from body wash and shampoo
• Hard water deposits that leave chalky white spots
• Mildew buildup in corners or along the shower door
• Abrasive cleaners that scratch the surface over time

Using the right cleaning approach prevents damage while keeping your shower or tub sparkling. Let’s dive into the step-by-step process.

How to Clean Acrylic Shower Walls (Step-by-Step Guide)

Cleaning an acrylic shower doesn’t require expensive products or hours of scrubbing. Follow these simple steps for sparkling results:

Step 1: Gather Your Cleaning Supplies

You’ll need:

• Mild dish soap (like Dawn dish soap)
• White vinegar
• Spray bottle
• Soft sponge or cloth
• Microfiber cloth for drying
• Warm water

Avoid using drain cleaner, bleach, ammonia, or any product labeled as abrasive. These can crack or cloud your new acrylic.

Step 2: Rinse the Walls with Warm Water

Before applying any cleaner, rinse the acrylic tub and shower walls with warm water to remove any loose dirt and soap scum. This makes the cleaning process more effective by loosening surface grime.

Step 3: Apply Your Cleaning Solution

Mix equal parts white vinegar and water in a spray bottle. Vinegar is an excellent natural cleaner that cuts through soap scum and mineral buildup without scratching. If you prefer something milder, use a few drops of dish soap mixed with warm water.

Spray the cleaning solution generously onto the shower walls, tub, and shower enclosure, as well as any other acrylic surfaces.

Step 4: Wipe Gently with a Non-Abrasive Sponge

Using a soft cloth or sponge, gently wipe the acrylic in circular motions. Avoid scrubbing too hard, as this can cause scratches on the surface. For tough spots in corners or around the shower door, use a soft-bristled brush to gently scrub before wiping clean.

Step 5: Rinse Thoroughly and Dry

Rinse the entire shower enclosure thoroughly with water to remove any remaining cleaning solution. Then, use a clean microfiber cloth to dry the surface completely. This step prevents water spots and keeps your acrylic looking its best.

For extra shine, you can also use a squeegee after rinsing to remove excess moisture.

Best Cleaners for Acrylic Shower Walls

Not all cleaning products are safe for acrylic. Here’s what you should use and what you should avoid.

Natural Cleaning Options

• Vinegar solution: Mix equal parts white vinegar and water in a spray bottle. This cuts through soap scum and hard water stains without damaging acrylic.
• Soap and water: A few drops of mild dish soap in warm water are gentle enough for regular cleaning.
• Baking soda paste: For tough stains, make a paste using baking soda and water. Apply gently, let it sit for 10 minutes, then rinse.

Commercial Cleaners

Look for products labeled “safe for acrylic” or “non-abrasive.” Formula 409 is one example that’s safe to use on plastic surfaces when diluted properly. Always test a small area first.

What to Avoid

Stay away from:

• Bleach or ammonia-based cleaners
• Abrasive cleaners or scouring powders
• Steel wool or rough brushes
• Acetone or paint thinners

These can cause cracks, cloudiness, or permanent scratches on your acrylic bath.

How to Remove Stubborn Stains or Hard Water Spots

Even with regular cleaning, you may encounter stubborn buildup. Here’s how to tackle it safely:

For Soap Scum

Mix baking soda with a small amount of water to form a paste. Apply it gently to the affected area using a soft cloth, then scrub lightly in circles. Rinse with warm water to remove all residue.

For Hard Water Stains

Spray a vinegar solution onto the stains and let it sit for 10–15 minutes. The acidity naturally breaks down mineral deposits. Wipe clean with a microfiber cloth and rinse thoroughly with water.

For Tough Grime

For particularly tough grime, spray white vinegar onto the area first. Then sprinkle baking soda over the same spot. Let the mixture fizz for a minute to break down the buildup. Gently scrub with a brush or sponge, then wipe and rinse thoroughly. This method cleans effectively while remaining safe for acrylic.

The ultimate guide to maintaining a clean acrylic shower? Establish a regular cleaning routine. Here’s how:

• Wipe down after each use: Use a dry microfiber cloth or squeegee to remove water and prevent soap scum from building up.
• Use a daily spray: Keep a spray bottle filled with a mixture of vinegar and water nearby. A quick mist after each shower prevents hard water deposits from forming.
• Deep cleaning once a week: Set aside time for a thorough scrub using your preferred cleaning solution.
• Avoid metal objects: Do not hang razors or metal caddies directly on acrylic surfaces. These items can rust and leave stains or scratches.
• Check ventilation: Proper airflow prevents mildew growth, which makes cleaning easier over time.

By using the right cleaning methods and maintaining consistency, you can keep your tub and shower looking brand new with minimal effort.

Keep Your Bathroom Looking Fresh

Cleaning an acrylic shower doesn’t have to be complicated or time-consuming. With gentle cleaning solutions, a soft cloth, and a little elbow grease, you can remove soap scum and mineral buildup while protecting the surface from scratches.

Remember: consistency is key. A quick wipe-down after each use prevents stubborn stains from forming in the first place. And when deep cleaning is necessary, use non-abrasive cleaners and tools specifically designed for plastic surfaces.

Follow these best practices, and your acrylic shower walls will stay shiny, clear, and scratch-free for years. This will help keep your bathroom looking clean and fresh without extra hassle.
