Of course! The method I recommend includes removing any visible mold or mildew with a mixture of equal parts white vinegar and water. Apply the mixture to the affected areas and let it sit for a few minutes before wiping it away with a damp cloth or sponge. Next, fill a bathtub with warm water and add a small amount of gentle detergent or baking soda. Place the vinyl shower curtain in the tub and use your hands to gently scrub it clean. Finally, rinse the shower curtain with warm water and hang it up to dry.
