How to Clean Your Shower Curtain Liner

Shower curtain liners are the unsung heroes of the bathroom. Invisibly protecting your shower curtain from water splashes, mold, and mildew, they are an integral part of maintaining a clean, sanitary bathroom. However, if not cleaned regularly, your shower curtain liner can become a breeding ground for bacteria, leading to unsightly stains and an unpleasant odor. But don’t despair or resort to buying a new one. With a bit of elbow grease and the right cleaning tools, you can restore your shower curtain liner to pristine condition. Here’s how:

Identify Your Shower Curtain Liner Material

Before you start the cleaning process, it’s crucial to identify what material your shower curtain liner is made from. Most are made from vinyl, PEVA (Polyethylene vinyl acetate), EVA (Ethylene-vinyl acetate), or fabric, each requiring slightly different cleaning methods. While many synthetic liners can be machine-washed, fabric liners may require a delicate wash or a hand wash.

Refer to the manufacturer’s instructions if available, as some materials may have specific cleaning instructions. If you’re unsure, it’s always better to err on the side of caution and use gentle, non-abrasive cleaning methods to avoid damage.

Weekly Maintenance

Weekly maintenance is key to prolonging the life of your shower curtain liner and minimizing the build-up of soap scum, mildew, and hard water stains.

Spraying Down

After each shower, spray down your curtain liner with a daily shower spray. This helps keep soap scum and mildew at bay. You can use store-bought shower sprays or make a DIY version. To make your own, mix equal parts white vinegar and water in a spray bottle. Vinegar is a natural disinfectant and deodorizer, capable of cutting through soap scum and preventing mildew growth.

Air it Out

Ensure that you fully extend the shower curtain liner after each use. This allows it to dry properly, minimizing damp areas where mildew can thrive. Keeping the bathroom well-ventilated also helps reduce humidity levels, making it less conducive for mold and mildew growth.

Deep Cleaning Your Shower Curtain Liner

Regardless of how well you maintain your shower curtain liner, it will need a thorough deep clean every now and then. This should be done every 2-3 months or whenever you notice a build-up of stains or a musty odor.

Machine Washing

If your liner is machine washable (like most vinyl, PEVA, EVA, or fabric liners), it can be cleaned in the washing machine. Remove the liner from the shower rod, and place it in the washing machine with a couple of towels. The towels will help scrub the liner clean during the wash cycle. Use warm water and a gentle detergent, then run the machine on a gentle cycle.

To help eliminate mildew and mold, add a cup of baking soda to your wash cycle, and a cup of vinegar during the rinse cycle. Remember to hang the liner to dry afterward; most synthetic liners are not dryer-safe.

Hand Washing

If your shower curtain liner isn’t machine washable, it can be cleaned in the bathtub. Fill the tub with warm water and a cup of baking soda. Let the liner soak for about an hour, then scrub it gently using a soft cloth or sponge. Rinely thoroughly and hang to dry.

Removing Tough Stains

For stubborn stains that persist after washing, you may need to employ a more targeted approach.

Using Vinegar

White vinegar is a versatile cleaner that’s great for dissolving hard water stains and soap scum. Spray undiluted vinegar on the problem area, let it sit for 10-15 minutes, then scrub gently with a non-abrasive sponge or cloth. Remember to rinse thoroughly afterward to remove the vinegar smell.

Using Bleach

If you have a clear or white liner, bleach can be an effective solution for removing stubborn mildew or mold stains. However, never use bleach on colored or patterned liners as it will discolor the material.

To use, dilute one part bleach with four parts water in a spray bottle. Spray the mixture on the stains and let it sit for a few minutes, then scrub gently. Rinse thoroughly after using bleach. Always use gloves and ventilate the area well when using bleach due to its strong, potentially harmful fumes.

Drying and Rehanging the Liner

Once your shower curtain liner is clean, it’s crucial to dry it properly to prevent the immediate regrowth of mold or mildew.

Air Drying

The best method for drying your liner is to hang it back up in the shower to air dry. Make sure to spread it out fully, so water isn’t trapped in the folds. Open windows or run the bathroom fan to increase ventilation and speed up the drying process.

Avoid the Dryer

Most shower curtain liners, especially those made from plastic or vinyl, should not be put in the dryer as the heat can cause them to warp or melt. If your liner is fabric and the care instructions allow it, you may be able to tumble dry on a low heat setting.


While regular cleaning is necessary, there are a few steps you can take to keep your shower curtain liner cleaner for longer.

Using a Water Softener

Hard water can leave mineral deposits on your liner, which can be tough to clean and can cause discoloration. Using a water softener can help prevent this, making your cleaning tasks easier in the long run.

Regular Ventilation

Ensuring your bathroom is well-ventilated will reduce the humidity levels, making it harder for mold and mildew to grow. Consider installing an exhaust fan if you don’t have one already.

A clean shower curtain liner not only makes your bathroom look more attractive but also reduces the risk of harmful mold and bacteria. It’s worth taking a little time every week for maintenance and every few months for a deep clean. Remember, prevention is better than cure when it comes to bathroom cleanliness. Happy cleaning!
