How to Clean a Shower Curtain Liner (Remove Mold and Soap Scum)

The shower curtain liner is the plastic or PEVA inner curtain that takes the direct hit from water, soap, and humidity. It's the most mold-prone item in the bathroom. Here's how to clean it and when to replace it.

What You'll Need

• LiBa PEVA Shower Curtain Liner — waterproof, non-toxic, rust-proof grommets, easy to replace when needed
• White vinegar
• Baking soda
• Amazon Basics Non-Scratch Sponges
• Laundry detergent (for machine washing)
• Rubber gloves

Method 1: Washing Machine (Easiest)

1. Remove the liner from the rings.
2. Place in the washing machine with 2 bath towels — the towels scrub the liner during the cycle.
3. Add laundry detergent and ½ cup of white vinegar.
4. Wash on a gentle cycle with warm water — never hot, which warps PEVA.
5. Remove immediately when done and hang back on the rod to air dry completely.
6. Never put in the dryer.

Method 2: Hand Wash in the Tub

1. Lay the liner flat in the bathtub.
2. Sprinkle baking soda over the mold and soap scum areas.
3. Spray with white vinegar — it will fizz.
4. Let sit for 15–20 minutes.
5. Scrub with a non-scratch sponge.
6. Rinse thoroughly and hang to dry fully spread out.

Removing Black Mold from a Liner

For black mold spots that won't respond to vinegar:

1. Mix 1 tablespoon of bleach per cup of water.
2. Apply to the mold spots with a sponge.
3. Let sit 10 minutes.
4. Scrub and rinse very thoroughly.

Important: Only use bleach on clear or white liners — it will discolor colored liners. If mold covers large areas or is deeply embedded, replace the liner.

When to Replace the Liner

• Mold that won't come out after cleaning
• Persistent musty smell even after washing
• Tears, holes, or deteriorating material
• Every 3–6 months as a general rule for hygiene

PEVA liners like the LiBa are affordable enough to replace regularly rather than spending time on deep cleaning.

Frequently Asked Questions

Is PEVA safer than PVC for shower liners?

Yes — PEVA (polyethylene vinyl acetate) is chlorine-free and doesn't off-gas the toxic chemicals that PVC liners do. PEVA liners are the safer, more eco-friendly choice for enclosed shower spaces.

How do I stop my shower liner from getting moldy so fast?

Spread the liner fully open after every shower so it dries completely. Mold grows in the folds. Run the exhaust fan for 15–20 minutes after showering. Spray the liner with diluted white vinegar weekly and let air dry.

Can I put a PEVA liner in the dryer?

No — heat melts and warps PEVA. Always air dry by hanging on the shower rod spread fully open.
