An acrylic bathtub is a luxurious yet delicate fixture that demands proper care to maintain its pristine condition. Cleaning an acrylic tub the right way ensures longevity, preserves its glossy finish, and eliminates harmful bacteria and grime. In this comprehensive guide, we will walk you through the best techniques to clean an acrylic bathtub, what products to use, what to avoid, and how to keep it looking new.
What Is an Acrylic Bathtub?
An acrylic bathtub is made from vacuum-formed acrylic sheets that are reinforced with fiberglass. These tubs are lightweight, retain heat well, and are available in various styles. However, acrylic is a soft material, meaning it's susceptible to scratches, stains, and discoloration if cleaned improperly.
Essential Tools and Supplies for Cleaning Acrylic Bathtubs
Before beginning the cleaning process, gather the following non-abrasive tools and gentle cleaning supplies:
Soft sponge or microfiber cloth
Liquid dish soap
White vinegar
Baking soda
Spray bottle
Plastic bucket
Old toothbrush (for corners and grout)
Warm water
Rubber gloves (optional)
Avoid using abrasive scrubbers, steel wool, or harsh chemicals like bleach or ammonia that can damage the acrylic surface.
Daily Maintenance Tips to Keep Your Acrylic Bathtub Spotless
Consistency is key in preventing grime buildup. Follow these quick daily maintenance tips:
Rinse the tub with warm water after every use to remove soap scum.
Wipe down the surface with a microfiber cloth or sponge to prevent water spots.
Dry the tub completely to avoid mineral deposits and mold.
Deep Cleaning Method: Weekly or Bi-Weekly Routine
For a more thorough cleaning session, follow these step-by-step instructions:
1. Fill the Bathtub with Warm Water
Plug the drain and fill the tub with warm (not hot) water until it reaches 2-3 inches. This helps loosen dirt and residue.
2. Add Gentle Cleaning Solution
Add two to three tablespoons of liquid dish soap or a mild acrylic tub cleaner to the water. Stir the mixture gently.
3. Let It Soak for 10-15 Minutes
Allow the soapy water to break down body oils, soap scum, and dirt. This soaking time is essential for an effective clean.
4. Scrub Gently
Drain the tub. Dampen a soft sponge or microfiber cloth with warm water. Scrub in circular motions, paying special attention to corners, edges, and high-touch areas.
5. Use a Baking Soda Paste for Tough Stains
If stains persist:
Mix baking soda with water to form a paste.
Apply to the stained areas and let sit for 10-15 minutes.
Scrub gently with a soft brush or sponge.
Rinse thoroughly.
6. Rinse with Clean Water
Use a bucket or handheld showerhead to rinse all residue off the tub. Ensure no cleaner or baking soda remains.
7. Dry and Buff the Surface
Use a clean microfiber towel to dry the tub. Buff the surface gently to restore its natural shine.
How to Remove Hard Water Stains from Acrylic Bathtubs
Hard water stains are common, especially in areas with high mineral content. To treat them:
Mix equal parts white vinegar and water in a spray bottle.
Spray generously over stained areas.
Let sit for 20–30 minutes.
Wipe with a soft sponge.
Rinse thoroughly and dry.
Caution: Do not use vinegar too frequently as excessive use may dull the acrylic finish over time.
How to Remove Mold and Mildew from Acrylic Bathtubs
Mold can appear around the caulking, grout, and under the rim of the tub. Here's how to clean it safely:
Make a solution of 1 part vinegar to 3 parts water.
Spray directly onto moldy areas.
Let sit for 15–20 minutes.
Scrub gently with an old toothbrush.
Rinse and dry the area completely.
For stubborn mold, substitute vinegar with hydrogen peroxide but avoid bleach-based cleaners which can damage acrylic.
