Shower curtain liners take a daily beating — constant moisture, soap, shampoo, and body oils create the perfect environment for soap scum, mildew, and mould to develop. A grimy liner makes an otherwise clean bathroom look dingy. The good news: plastic and PEVA liners are easy to clean, and most can go right in the washing machine.
What You'll Need
- Washing machine
- White vinegar
- Baking soda
- Dish soap or laundry detergent
- Old towels (for machine washing)
- Spray bottle (for hand cleaning)
- Soft brush or sponge
Method 1: Machine Washing (Easiest)
Most plastic (PEVA, EVA, or vinyl) shower curtain liners are machine washable. Remove the liner from the curtain rod and toss it in the washing machine along with two or three old bath towels — the towels act as gentle scrubbers and prevent the liner from bunching.
Add 1/2 cup of white vinegar to the drum (or fabric softener compartment) and your regular amount of laundry detergent. Run the machine on a warm, gentle cycle. Do not put in the dryer — the heat will melt or warp the liner. Remove immediately after the wash cycle, shake it out, and rehang it. It will air-dry within an hour.
Method 2: Hand Cleaning in the Shower
For spot cleaning or liners that aren't machine washable, hand cleaning in the shower works well. Keep the liner hanging and spray it down with a solution of equal parts white vinegar and water. Let it sit for 5–10 minutes. For mildew spots, sprinkle baking soda directly onto the affected area after the vinegar spray — the fizzing reaction helps loosen mould and mildew. Scrub with a soft brush or sponge and rinse thoroughly with the shower head.
Tackling Stubborn Mould
For black mould spots that don't respond to vinegar, lay the liner flat (in the tub or on a clean outdoor surface) and apply a diluted bleach solution (1 tablespoon bleach per litre of water) directly to the moulded areas. Let it sit for 5 minutes, then scrub with a brush and rinse well. Only use bleach on white or clear liners — it will discolour coloured liners.
Preventing Buildup
- After every shower, spread the liner flat across the rod to allow it to dry rather than bunching it at one end where moisture pools
- Run the bathroom exhaust fan during and after showers to reduce humidity
- Spray the liner with a diluted white vinegar solution once a week as a preventive measure
- Replace the liner every 6–12 months — they're inexpensive and impossible to fully restore once mould has penetrated deeply
How Often Should You Clean the Liner?
Aim for a full clean once a month. A quick vinegar spray weekly prevents the buildup that makes monthly cleaning take longer. If you see mould appearing between monthly cleans, increase the frequency of your preventive vinegar spray or improve bathroom ventilation.
