If you’ve noticed your once-clear plastic shower curtain becoming cloudy with soap scum, mildew, or mold, you’re not alone. That unsightly buildup doesn’t mean you need to replace your curtain entirely. Many homeowners don’t realize that plastic shower curtains and liners can be effectively cleaned in a standard washing machine, saving money and reducing waste. This comprehensive guide will walk you through the process of safely washing your plastic shower curtain, extending its life, and keeping your bathroom looking fresh and clean.

Can You Really Wash a Plastic Shower Curtain in the Washing Machine?
The short answer is yes! Despite what many people believe, most plastic shower curtains and liners can be safely cleaned in a washing machine. However, there are some important considerations and techniques to ensure you don’t damage your curtain or your washing machine in the process.
Benefits of Machine Washing Your Shower Curtain
- Thorough cleaning: Removes soap scum, mildew, and bacteria more effectively than hand washing
- Time-saving: Less effort than scrubbing by hand
- Extends curtain life: Regular cleaning prevents permanent staining and deterioration
- Cost-effective: Avoid frequent replacements of shower curtains
- Eco-friendly: Reduces plastic waste from disposable curtains
What You’ll Need to Wash Your Plastic Shower Curtain
Before you begin, gather these items:
- Your plastic shower curtain or liner
- Washing machine
- Mild detergent (avoid harsh chemicals)
- White vinegar
- Baking soda
- 2-3 light-colored towels
- Shower curtain rings or hooks (optional replacement)
Step-by-Step Guide to Washing Your Plastic Shower Curtain
Step 1: Preparation and Pre-Treatment
- Take down your shower curtain carefully, removing it from the hooks or rings
- Give it a quick shake to remove loose debris or water droplets
- Check the care label (if present) for any specific washing instructions
- Inspect for any tears or damage that might worsen during washing
Pro tip: For heavily soiled curtains with mildew, spray a solution of equal parts water and white vinegar on visible mold or mildew spots and let sit for 10-15 minutes before washing.
Step 2: Loading the Washing Machine
The key to successfully washing a plastic shower curtain is to provide cushioning to prevent the plastic from bunching up, tearing, or wrapping around the agitator.
For top-loading machines:
- Place the shower curtain into the machine, spreading it out as much as possible
- Add 2-3 light-colored towels to provide cushioning
- Make sure the curtain isn’t tightly bunched up
For front-loading machines:
- Carefully place the shower curtain inside, spreading it around the drum
- Add towels to balance the load and provide protection
- Close the door ensuring the curtain isn’t caught in the door seal
Step 3: Selecting the Right Detergent and Additives
The cleaning agents you choose can make a significant difference in results:
- Detergent: Use a mild liquid detergent (about 1/4 of the normal amount)
- Vinegar: Add 1/2 cup of white vinegar as a natural disinfectant and to remove soap scum
- Baking soda: Add 1/2 cup of baking soda to boost cleaning power and eliminate odors
Avoid these products:
- Bleach (can damage and yellow plastic)
- Fabric softener (leaves residue on plastic)
- Harsh chemical cleaners
- Full-strength detergents (too sudsy for plastic)
Step 4: Choosing the Right Washing Settings
Plastic shower curtains require gentle treatment in the washing machine:
Temperature setting:
- Use cold or warm water (never hot)
- Hot water can warp, melt, or damage plastic curtains
- 86°F (30°C) is typically the ideal temperature
Cycle selection:
- Choose a gentle or delicate cycle
- Short washing cycle (5-8 minutes maximum)
- Low spin speed to prevent damage
Special Considerations for Different Washing Machines
How to Wash in a Front-Loading Machine
Front-loading machines are actually ideal for washing plastic shower curtains as they lack an agitator that could potentially damage the plastic.
- Spread the curtain out along the inside drum wall
- Add several towels to balance the load
- Use half the recommended detergent amount
- Select a gentle cycle with cold water
- Optional: stop the machine before the final spin cycle or reduce spin speed
How to Wash in a Whirlpool or Top-Loading Machine
Top-loading machines, especially those with center agitators, require extra care:
- Arrange the curtain loosely around the agitator
- Add towels to prevent the curtain from wrapping around the agitator
- Use cold water and a gentle cycle
- Consider stopping the machine periodically to untangle the curtain if necessary
Washing Plastic Shower Curtains with Special Features
Can You Wash Shower Curtains with Magnets?
Yes, most shower curtains with magnets can be machine washed safely. The magnets are typically securely sealed within plastic pockets at the bottom of the curtain. However:
- Check that magnetic seams are intact before washing
- Use a more gentle cycle
- Avoid high spin speeds that might dislodge magnets
- Listen for any unusual sounds during washing that might indicate loose magnets
Weighted Shower Curtains
For curtains with weights or weighted hems:
- Inspect the weights to ensure they’re secure
- Use a gentle cycle with minimal agitation
- Consider placing the curtain in a mesh laundry bag for extra protection
- Check post-washing to ensure weights remain properly sealed in their pockets
Drying Your Plastic Shower Curtain
After washing, proper drying is essential:
- Remove immediately after the cycle ends to prevent new wrinkles and creases
- Shake gently to remove excess water
- Hang to air dry in its regular position on the shower rod
- Spread it out fully to prevent water droplets from forming new mildew spots
- Leave bathroom door open or use fans to circulate air for faster drying
Important: Never put a plastic shower curtain in the dryer, as the heat can melt, warp, or shrink the plastic.
How to Clean a Plastic Shower Curtain Without Removing It
If removing your shower curtain seems like too much hassle, here’s a method to clean it in place:
- Fill a spray bottle with equal parts white vinegar and water
- Spray the solution liberally on both sides of the curtain
- Let sit for 10-15 minutes
- Use a microfiber cloth or soft sponge to wipe down the curtain
- Rinse thoroughly with the shower head
- Leave curtain extended (not bunched up) to dry completely
While this method works for light cleaning, it won’t be as effective as machine washing for removing stubborn mildew or heavy soap scum.
How Often Should You Wash Your Plastic Shower Curtain?
To maintain cleanliness and prevent stubborn buildup:
- Light cleaning/spray down: Weekly
- Full machine washing: Every 1-3 months, depending on usage
- Immediate attention: Anytime you notice mildew spots forming
Pro tip: Daily habits that extend time between washes include squeegeeing the curtain after showers and leaving it extended (not bunched up) to dry.
Preventing Mildew and Extending Curtain Life
Implement these preventive measures to keep your shower curtain cleaner longer:
- After each shower: Pull the curtain closed to allow even drying
- Weekly maintenance: Spray with vinegar solution to prevent mildew
- Improve ventilation: Use bathroom fans, open windows, or leave the door open
- Consider fabric alternatives: For those tired of plastic, polyester fabric curtains are machine-washable and typically more mildew-resistant
Temporary Solutions for Shower Privacy During Washing
If you’re washing your only shower curtain and need privacy in the meantime:
- Hang a clean bed sheet temporarily
- Use a large beach towel suspended from the rod
- Consider keeping a backup curtain for rotation
When to Replace Your Plastic Shower Curtain
Even with regular cleaning, plastic shower curtains won’t last forever. Consider replacement when:
- Tears or holes develop that can’t be repaired
- Permanent discoloration persists after washing
- Material becomes brittle or consistently develops mold despite cleaning
- Weighted hems or magnets become damaged or detached
Environmental Considerations
When replacing shower curtains, consider these eco-friendly options:
- PEVA curtains (PVC-free plastic alternative)
- Biodegradable or recyclable options
- Fabric curtains (longer lasting with proper care)
- Reusing old curtains for other purposes (garden protection, drop cloths, etc.)
Final Thoughts
Washing your plastic shower curtain in the washing machine is a simple, effective way to extend its life and keep your bathroom looking fresh. With the right approach—gentle cycles, proper additives, and careful handling—you can transform a grimy shower curtain into one that looks almost new again. Regular maintenance not only saves money but also reduces waste by preventing premature replacement.
Remember that prevention is the best strategy—developing habits like leaving the curtain extended after use and improving bathroom ventilation can significantly reduce mildew growth and the frequency of deep cleaning needed.
By following these guidelines, you’ll maintain a cleaner, healthier bathroom environment while extending the life of your shower curtain significantly.
