Place the shower curtain in a washing machine. Add 1 cup of baking soda and wash it in warm water on the gentle cycle. Remove the curtain immediately after the wash cycle ends.
Hang the shower curtain on an outdoor clothesline to dry. It is important to place the curtain in the shade because sunlight may harm the vinyl.
Leave the curtain to air outdoors for at least 24 hours, weather permitting. If a strong odor remains, leave it for another 24 hours. Off-gassing takes time to subside.
Carry the curtain indoors and attach it to the shower curtain rod. Leave the bathroom windows and doors open to allow a good air flow to the bathroom. The air flow helps disperse more of the odor.
Things You Will Need
- Baking soda
- You can hand wash (rather than machine wash) a vinyl curtain by scrubbing it down with baking soda and a mild detergent, then rinsing it well. Washing new curtains frequently (once a week) may diminish new vinyl odor more quickly. After each washing, hang the curtain to dry in the open air.
