How to Clean a Shower Curtain and Liner
Shower curtains and plastic liners accumulate soap scum, body oils, hard water deposits, and mildew — primarily on the lower portion that stays wet the longest. Most curtains and liners are machine washable, which makes cleaning simple. The key is frequency: monthly washing prevents heavy buildup.
Machine Washing a Fabric Shower Curtain
Remove from the hooks and wash in the washing machine on a warm gentle cycle with your regular detergent. Add ½ cup of baking soda to the wash cycle to boost deodorizing. Add a few towels to the load — they provide gentle scrubbing action against the curtain fabric. Do not put in the dryer if the curtain has decorative elements or if it's prone to shrinkage — hang back on the rod to air dry while still damp to prevent wrinkles.
Machine Washing a Plastic Liner
Plastic liners can be machine washed on a cold gentle cycle. Add ½ cup of white vinegar instead of fabric softener during the rinse cycle — vinegar dissolves soap scum and inhibits mildew. Add a couple of towels for scrubbing action. Remove promptly and rehang immediately — heat from drying melts or warps plastic liners, so never machine dry them.
Pink Mildew Stains
Pink or orange discolouration at the bottom of a liner is caused by a bacterium called Serratia marcescens, common in shower environments. Spray affected areas with undiluted white vinegar before washing, or soak in a solution of 1 tablespoon of bleach per gallon of water for 15 minutes (white/clear liners only). Rinse thoroughly before machine washing.
Preventing Buildup
- Extend the curtain fully after every shower so it dries evenly
- Run the bathroom fan during and after showering to reduce humidity
- Spray the lower third of the liner with diluted vinegar weekly
- Replace plastic liners every 6–12 months — they are inexpensive and hard to fully clean once heavily stained
