How to clean mildew off a shower curtain liner

Last updated: October 30, 2026 8:00:00 AM

Remove unsightly mildew from your shower curtain liner by soaking it in a warm water and vinegar solution. Scrub away any remaining stains gently before hanging it back up to dry completely.

To clean mildew off a shower curtain liner, you need to remove it from the hooks and either run it through a washing machine with detergent and vinegar or scrub it manually in a tub using a mild abrasive and warm water. This process restores clarity and eliminates the musty odors that accumulate in humid bathrooms.

A shower curtain liner is a high-maintenance household item. Because it hangs in a constant state of dampness and rarely gets a chance to dry completely, it acts as a magnet for mold, mildew, and pink soap scum. Water splashes against the plastic or fabric, soap residue clings to the surface, and the dark, humid environment creates ideal conditions for microbial growth. While many people assume a spotted or stained liner is ruined and throw it away, most liners can be saved with minimal effort and common household supplies.

Remove the liner and inspect the fabric

Take the liner down from the shower rod completely, pulling the rings or hooks out of the eyelets. Lay the liner flat in a clean bathtub or take it outside if the weather permits. Unfolding the liner allows you to see the full extent of the mildew growth and identify any tears, rips, or brittle areas that might not survive the cleaning process.

Check the bottom hem, which usually collects the most moisture and grime. If the plastic has become permanently warped, excessively stiff, or torn around the hanging grommets, cleaning may not be worth the effort, and a replacement is the safer choice. However, if the damage is strictly cosmetic—meaning black, gray, or pink spots caused by mildew—proceed with the cleaning stages.

Choose a washing method based on the material

Examine the care tag attached to the top corner of the liner to determine its composition. Most budget-friendly liners are made of vinyl or PEVA, while higher-end or decorative liners are made of woven fabric like polyester or nylon.

If the tag indicates the liner is machine washable, you can save yourself a lot of physical labor. Fabric liners almost always belong in the washing machine, and many heavy-duty plastic or vinyl liners can also withstand a gentle cycle. For machine washing, place the liner into the drum alongside a couple of old bath towels. The towels serve a dual purpose: they gently scrub against the liner during agitation to loosen stubborn mildew, and they cushion the plastic so it does not tear against the inner drum of the machine.

If the tag explicitly prohibits machine washing, or if the liner is extremely thin and fragile, plan to clean it by hand in the bathtub.

Wash the liner with detergent and vinegar

Set the washing machine to a gentle or delicate cycle to prevent the spin cycle from creasing or tearing the plastic. Avoid using hot water, as high heat can melt thin plastic liners or set mildew stains permanently into the material.

For hand-washing in the tub, fill the basin with warm water and mix in a squirt of dish soap and a cup of white vinegar. Submerge the liner and let it soak for a while to soften the grime. Use a soft-bristled brush, a sponge, or a microfiber cloth to wipe down both sides of the liner, paying close attention to the bottom weighted hem and the folds where water tends to pool.

Hang the liner back up to dry

The final step is letting the liner dry properly so the remaining mildew spores cannot multiply. Reattach the liner to the shower hooks or rings, ensuring it hangs fully extended inside the tub enclosure. Smooth out any folds or wrinkles so air can circulate freely across the entire surface.

Leave the bathroom door open and turn on the exhaust fan to pull out excess humidity. If your bathroom lacks a window or a strong fan, point a small electric fan toward the tub area to speed up the drying process. Keeping the bathroom ventilated for the rest of the day ensures the liner dries completely within a few hours.

Prevent future mildew growth

Preventing mildew is far easier than cleaning it off after it takes over. Simple daily habits can drastically extend the time between deep cleanings.

After every shower, pull the liner completely closed across the length of the tub rather than bunching it up against one side of the wall. Bunching traps moisture within the folds, creating a dark, wet pocket where mildew thrives. Spreading the liner flat lets it dry uniformly in the ambient air of the room.

If you notice a faint pink film or small gray dots beginning to form near the bottom hem, address them immediately by wiping the area with a damp cloth and a splash of vinegar rather than waiting for a heavy infestation to develop. Regularly wiping down the lower edges of the liner once a week keeps soap scum from accumulating, which in turn denies mildew the organic matter it needs to grow.
