Open the window in your bathroom or turn on the ventilator fan to help remove excess moisture.
Shake out the liner and separate any folds in your shower curtain to release trapped moisture. Also consider putting an empty laundry basket or a hook in the tub to hold the wet shower curtain away from the tub side.
Move the shower curtain to the outside of the bathtub only after it has dried partially to prevent water from dripping onto your bathroom floor.
Use a dry towel or rag to remove water from the wet side of your shower curtain after you shower.
If you use a commercial cleaning product, use the product as directed by the manufacturer. To make a natural cleaning solution, mix together 1 part warm water and 1 part distilled white vinegar and pour the mixture into a spray bottle. You can substitute bleach for vinegar; however, you will be required to properly ventilate your bathroom after using the bleach mixture to prevent adverse health effects from the toxic fumes.
Spray your cleaning solution over the entire surface of your shower curtain. Use a clean, dry towel or rag to spread the cleaning solution over the entire surface of the shower curtain.
