How to Clean a Shower Curtain : Easy Vinegar & Baking Soda Methods

To clean a shower curtain, wash it with baking soda, white vinegar and warm water — by hand or on a gentle machine cycle — to remove mould, mildew and soap scum fast. Hang to air dry for a fresher, hygienic Australian bathroom without harsh chemicals.

Keeping your bathroom spotless can be tricky — especially the shower curtain. Between mould, soap scum and hard water stains, warm and humid conditions across Australia can quickly turn a fresh curtain into a maintenance headache. This guide shows you how to wash a shower curtain properly, when to replace it, and how to keep it cleaner for longer — tailored to the Australian climate.

Why You Should Clean Your Shower Curtain Regularly

  • Prevents odours by removing trapped moisture and residue.
  • Extends the lifespan of fabric, polyester, PEVA and PVC curtains.
  • Keeps your bathroom looking bright and hygienic.
  • Reduces allergy risks from mould spores in humid regions (QLD, NT, coastal NSW).

How Often Should You Clean It? (Australia)

Fabric/Polyester: every 2–4 weeks.
Plastic/PEVA: every month (more if you live in tropical or coastal areas).

Tip: After each shower, fully extend the curtain so it dries faster and discourages mildew.

Option 1 — Clean in the Washing Machine

Best for fabric and many machine-washable polyester curtains.

What you’ll need

  • Mild detergent
  • ½ cup baking soda
  • ½ cup white vinegar
  • Two clean towels (to cushion and reduce creasing)

Steps

  1. Remove the curtain and place it in the washer with two towels.
  2. Add detergent and ½ cup baking soda.
  3. Run a gentle warm cycle (eco/delicate on AU front-loaders works well).
  4. During rinse, add ½ cup white vinegar.
  5. Hang to air dry — do not tumble dry.

Option 2 — Hand Wash in the Tub or Laundry Sink

Ideal for plastic, PEVA and PVC curtains that may warp in a machine.

What you’ll need

  • Mild detergent
  • Warm water
  • Sponge or soft cloth
  • White vinegar (optional)

Steps

  1. Fill the tub with warm water and a small amount of detergent.
  2. Soak the curtain for 20–30 minutes.
  3. Gently scrub stains or mould spots.
  4. Rinse thoroughly.
  5. Hang outside in the Australian sun to naturally deodorise and dry.

Option 3 — 5-Minute Refresh (No Removal)

  1. Mix equal parts white vinegar and water in a spray bottle.
  2. Spray the curtain (focus on soap scum and mildew areas).
  3. Wait 10 minutes, wipe with a microfibre cloth.
  4. Rinse with the showerhead and let it dry fully.

How to Remove Mould & Mildew

Natural remover: 1 part white vinegar + 1 part water + 2 tbsp baking soda. Spray, wait 15 min, scrub gently, rinse.

For stubborn patches: Use a 1:10 diluted bleach solution with good ventilation and gloves. Never mix bleach with vinegar or ammonia.

How to Keep Your Shower Curtain Clean Longer

  • Dry it: Fully extend after every shower.
  • Use a liner: A washable PEVA liner shields fabric curtains from soap and moisture - Find our PEVA Shower Curtains Black and Grey
  • Ventilate: Run the exhaust fan or open a window to cut humidity.
  • Weekly spray: Water + vinegar + a few drops of tea tree oil (Aussie favourite) to deter mildew.
  • Avoid harsh chemicals: Kinder for your curtain and the environment.

Eco-Friendly Cleaning Tips

  • Choose biodegradable detergents to protect waterways.
  • Air dry outdoors instead of machine drying.
  • Consider fabric or linen curtains as plastic-free options.
  • Use gentle cycles on efficient front-loaders to save water and power.

When Should You Replace a Shower Curtain?

  • Plastic/PEVA: every 6–12 months.
  • Fabric/Polyester: every 1–2 years.

Replace sooner if you notice persistent odour, discolouration, tears, or recurring mould.
