Machine washing your shower curtain
You'll need to use a washing machine for this method
Step 1: Take down your shower curtain or liner and put it in the washing machine, removing any metal rings that may be attached.
Step 2: Add one or two bath towels to the machine. This will help to scrub the shower curtain and will also prevent it from wrinkling, sticking to itself and getting torn.
Step 3: Add the usual amount of laundry detergent and half a cup to one cup of baking soda.
Step 4: Put the machine on a gentle and warm setting.
Step 5: When the washing machine switches to the rinse cycle, pour in a half cup to one cup of distilled white vinegar.
Step 6: When the cycle is finished, hang your shower curtain or liner up to drip-dry.
