Just because your plastic shower curtain or liner gets dirty or mildewed doesn’t mean you have to throw it away. Try cleaning it in your washing machine with two bath towels on the gentle setting. Add 1/2 cup baking soda to your detergent during the wash cycle and 1/2 cup vinegar during the rinse cycle. Let it drip-dry; don’t put it in the dryer.
Get mold and mildew off your shower curtains. Wash them — along with a couple of bath towels (to prevent the plastic curtains from crinkling) — in warm water with 1/2 cup chlorine bleach and 1/4 cup laundry detergent. Let the washer run for a couple of minutes before loading. Put the shower curtain and towels in the dryer on the lowest temperature setting for 10 minutes, then immediately hang-dry.
Clean those ugly mildew stains off your plastic shower curtain by putting it and a couple of soiled towels in your washing machine. Add 1/2 cup laundry detergent and 1/2 cup baking soda to the load, and wash it in warm water on your machine’s regular cycle. Add 1 cup white vinegar to the first rinse. Before the machine goes into the spin cycle, remove the curtain and let it hang-dry.
