Mold thrives in humid, damp environments. This makes your bathroom ideal breeding ground for mould growth. It is not uncommon to find mould on your fabric shower curtain. There is no need to throw out the curtain just because of some mould spots. There are products and methods that are used to effectively remove mould from fabric shower curtains. The best part is that you probably already have these products right at home.
Take down the shower curtain. If possible, take the shower curtain outdoors.
Scrub the mouldy shower curtain with a stiff scrub brush. If you cannot take the shower curtain outside, brush it off over newspapers. Roll up the paper and discard promptly after brushing off the mould.
Wash the fabric shower curtain according to the label's care instructions. Treat with a laundry pretreatment spray and use the hottest water setting allowed for the fabric. Add 1 cup white vinegar to the washer. If the fabric allows, let it soak in the washer with laundry detergent and vinegar for a couple of hours.
Lay or hang the shower curtain in the sun to dry. Do not place the curtain in the dryer until you are sure that all of the mould is gone.
Treat the mould spots with lemon juice and salt if the mould spots remain. Saturate the mould spots with lemon juice. Sprinkle table salt on top of the lemon juice. Use a rag to rub the mixture into the fabric.
Allow the lemon juice and salt to sit on the fabric shower curtain for a couple hours. Launder the item as usual. Let the shower curtain dry in the sun.
If your fabric shower curtain is white, substitute 1 cup chlorine bleach for the white vinegar in the washer. Do not mix vinegar and chlorine bleach together as the results could be toxic.
