Plastic shower curtains are affordable, practical bathroom necessities that protect your floor from water damage while adding style to your space. However, they’re also notorious for developing unsightly mold, mildew, and soap scum buildup. The good news? You don’t need to throw away your dirty shower curtain and buy a new one every few months. With proper cleaning techniques, you can extend the life of your plastic shower curtain significantly. This comprehensive guide will walk you through everything you need to know about washing plastic shower curtains effectively, whether you use a washing machine or prefer cleaning by hand.

Can Plastic Shower Curtains Be Machine Washed?
Yes, most plastic shower curtains and liners can be safely washed in a washing machine. This might come as a surprise to many homeowners who assume plastic curtains are too delicate for machine washing. In reality, the washing machine is one of the most effective and convenient ways to clean a plastic shower curtain.
However, before tossing your curtain into the washer, check the care label for any specific instructions or warnings from the manufacturer. While most vinyl, PEVA, and plastic shower curtains are washing machine-safe, some specialty curtains or those with delicate decorative elements might require hand washing.
How to Wash a Plastic Shower Curtain in a Washing Machine
Standard Top-Loading Machine Method
Follow these steps for a thorough clean in a top-loading washing machine:
- Remove the curtain carefully: Take the curtain off the rod by unhooking it from the shower rings or hooks. Shake it gently to remove any loose debris.
- Add gentle cleansers: Place the curtain in the washing machine and add a few soft towels to prevent excessive wrinkling and provide gentle scrubbing action. The towels also help balance the load.
- Choose the right detergent: Add a small amount (about half the normal amount) of mild detergent. Avoid bleach as it can damage or discolor plastic curtains.
- Add natural cleaning boosters: For extra cleaning power, add ½ cup of baking soda during the wash cycle and ½ cup of white vinegar during the rinse cycle. This combination helps eliminate odors and dissolve soap scum.
- Select gentle settings: Use the gentle or delicate cycle with warm (not hot) water. Hot water can warp or damage plastic material.
- Skip the spin cycle: If possible, stop the machine before the spin cycle or use the lowest spin setting to prevent damage.
How to Wash a Plastic Shower Curtain in a Front-Loader
Front-loading machines require a slightly different approach:
- Prepare the curtain: As with top-loaders, remove the curtain and shake off excess water and debris.
- Load properly: Place the shower curtain in the machine along with 2-3 light-colored towels to provide cushioning and balance.
- Use appropriate cleansers: Add a small amount of mild detergent and ½ cup of baking soda to the detergent compartment.
- Add vinegar: Put ½ cup of white vinegar in the fabric softener dispenser to be released during the rinse cycle.
- Select settings carefully: Choose a gentle or delicate cycle with warm water (around 30-40°C or 85-105°F).
- Reduce spin speed: Set the spin cycle to the lowest setting to prevent damage to the plastic material.
Front-loading machines typically use less water, which can be beneficial for the environment but might require an extra rinse cycle to ensure all soap residue is removed from your shower curtain.
What Temperature Should You Wash a Shower Curtain At?
Temperature plays a crucial role in effectively cleaning your plastic shower curtain without causing damage. The ideal water temperature for washing plastic shower curtains is warm, around 30-40°C (85-105°F).
Here’s why temperature matters:
- Too hot: Temperatures above 40°C (105°F) can warp, melt, or deform plastic curtains
- Too cold: Water below 30°C (85°F) may not effectively remove soap scum and body oils
- Just right: Warm water dissolves dirt and soap residue while being gentle on the plastic material
Most washing machines have temperature settings, but if yours doesn’t, the “warm” setting usually falls within this ideal range. When in doubt, err on the side of cooler water to prevent damage.
How to Clean a Plastic Shower Curtain by Hand
Not everyone has access to a washing machine or feels comfortable machine-washing their shower curtain. Hand washing is an effective alternative that gives you more control over the cleaning process.
Simple Hand Washing Method
- Fill the bathtub: Add a few inches of warm water to your bathtub or a large sink.
- Add cleaning solution: Mix in 1 cup of white vinegar, ½ cup of baking soda, and a small amount of mild detergent.
- Submerge the curtain: Lay the shower curtain flat in the water, ensuring it’s fully submerged.
- Soak and scrub: Let it soak for 1-2 hours. For stubborn stains or mildew, use a soft brush or sponge to gently scrub affected areas.
- Rinse thoroughly: Drain the dirty water and rinse the curtain with clean, warm water until all soap residue is gone.
- Dry properly: Hang the curtain back on the shower rod to air dry. Keep bathroom windows open or fans running to speed up drying.
Spot Treatment for Stubborn Stains
For targeted cleaning of particularly stubborn mildew or soap scum:
- Create a paste using equal parts baking soda and water.
- Apply the paste directly to stained areas.
- Let it sit for 10-15 minutes.
- Scrub gently with a soft brush or sponge.
- Rinse thoroughly with warm water.
How to Clean a Plastic Shower Curtain Without a Washing Machine
If you don’t have a bathtub or prefer not to use it for cleaning, here’s an alternative method:
Spray and Wipe Method
- Create a cleaning solution: In a spray bottle, mix equal parts white vinegar and water with a few drops of dish soap.
- Leave the curtain hanging: Keep the curtain on the rod for easier handling.
- Spray generously: Apply the solution to both sides of the curtain, focusing on areas with visible buildup.
- Let it work: Allow the solution to sit for 10-15 minutes to break down soap scum and mildew.
- Wipe down: Use a microfiber cloth or soft sponge to wipe the curtain from top to bottom.
- Rinse carefully: Use a handheld shower head or a clean, damp cloth to remove all cleaning solution.
- Air dry: Leave the curtain extended on the rod to dry completely.
Can You Wash Shower Curtains with Magnets?
Many plastic shower curtains and liners have magnets sewn into the bottom hem to help them stick to the tub and prevent water from escaping. The good news is that these magnets are typically sealed in waterproof pockets and can safely go through the washing machine.
However, to protect both the magnets and your washing machine:
- Use a gentle cycle with low agitation
- Skip high-speed spin cycles
- Add towels to the load to provide cushioning
- Check the magnets after washing to ensure the pockets remain sealed
For curtains with particularly heavy magnets or if you’re concerned about damage, hand washing might be the safer option.
How Often Should You Wash a Shower Curtain?
The frequency of cleaning depends on several factors including:
- Bathroom ventilation
- Number of people using the shower
- Local climate and humidity levels
- Whether you squeegee or wipe down the curtain after showering
As a general guideline:
- Deep cleaning: Wash your plastic shower curtain thoroughly every 1-3 months
- Maintenance cleaning: Spray with a daily shower cleaner and wipe down weekly
- Immediate attention: Address visible mildew or mold as soon as it appears
Households with higher humidity, multiple shower users, or limited ventilation will need to clean more frequently. Establishing a regular cleaning schedule helps prevent severe buildup that becomes difficult to remove.
Can You Put Shower Curtains in the Dryer?
Most plastic shower curtains should not be placed in the dryer. The heat can cause the plastic to warp, melt, or stick together. Even on the lowest heat setting, tumble drying can damage the material and significantly shorten your curtain’s lifespan.
Instead, after washing:
- Shake off excess water
- Hang the curtain back on the shower rod
- Extend it fully to prevent creasing
- Use a towel to gently blot excess moisture if needed
- Ensure proper bathroom ventilation to speed drying
Air drying is the safest method for plastic shower curtains and typically only takes a few hours.
Prevention Tips to Keep Your Shower Curtain Cleaner Longer
Proactive maintenance can significantly extend the time between deep cleanings:
- Daily habits: After showering, pull the curtain closed fully to allow for even air drying and prevent moisture from being trapped in folds.
- Weekly maintenance: Spray the bottom third of the curtain (where most buildup occurs) with a mixture of equal parts water and white vinegar.
- Proper ventilation: Use bathroom fans during and after showering, or keep windows open when possible to reduce humidity.
- Shower curtain materials: Consider upgrading to mildew-resistant materials like PEVA or fabric curtains with mildew-inhibiting treatments.
- Double-curtain approach: Use a decorative fabric outer curtain with a plastic liner inside. The liner protects from water and can be more easily washed or replaced.
Eco-Friendly Cleaning Alternatives
For environmentally conscious homeowners, these natural alternatives work effectively:
- Vinegar and baking soda: The classic combination works wonders without harsh chemicals.
- Lemon juice: Add ¼ cup to your washing solution for additional cleaning power and a fresh scent.
- Essential oils: A few drops of tea tree, eucalyptus, or lavender oil added to cleaning solutions can inhibit mildew growth and leave a pleasant aroma.
- Hydrogen peroxide solution: A 3% solution can be sprayed directly on mildew spots as a natural alternative to bleach (test on an inconspicuous area first).
When to Replace Your Plastic Shower Curtain
Even with proper care, plastic shower curtains don’t last forever. Signs it’s time for replacement include:
- Persistent mold or mildew that won’t come off with cleaning
- Discoloration that doesn’t improve with washing
- Tears, holes, or damaged seams
- Brittle plastic that has lost flexibility
- Constant musty odor despite cleaning attempts
Most plastic shower curtains last 1-2 years with proper care, though higher-quality materials may last longer.
