Shower curtains naturally collect soap scum, water stains, and moisture over time. If your bathroom does not have good ventilation, the bottom of the curtain may also start to develop mildew or a musty smell. Cleaning a shower curtain is usually simple. The key is to choose the right method for the material and let the curtain dry completely afterward.
In general, many fabric shower curtains can be machine washed, while plastic or vinyl shower curtain liners are often better cleaned with warm water, mild detergent, baking soda, or a gentle wash cycle. Before washing, always check the care label to avoid damaging the curtain with high heat, bleach, or the wrong cleaning method.
How Often Should You Clean a Shower Curtain?
For most homes, cleaning a shower curtain about once a month is a good routine. If your bathroom holds a lot of moisture, has poor ventilation, or the bottom of the curtain often stays damp, you may need to clean it more often.
The shower curtain liner usually needs more attention than the outer curtain because it sits closer to water, soap, and humidity. Cleaning the liner every 2 to 4 weeks can help prevent buildup. It also helps to wipe the curtain rod, rings, and lower edge of the curtain from time to time.
If you notice a musty smell, yellow stains, dark spots, or soap scum along the bottom, it is time to clean the curtain.
Can You Put a Shower Curtain in the Washing Machine?
Many fabric shower curtains can be washed in the washing machine. Before washing, remove the curtain from the rod and take off the hooks or rings. Use a mild detergent, choose a gentle cycle, and wash with cold or warm water.
If the curtain has decorative trim, embroidery, special texture, or delicate fabric, hand washing may be safer. After washing, air drying is usually the best choice unless the care label says low-heat drying is allowed.
Some plastic shower curtain liners can also be machine washed, but they should not be exposed to high heat. Adding a few old towels to the wash can help gently scrub the surface and remove soap scum.
How to Clean a Plastic Shower Curtain Liner
Plastic shower curtain liners often collect the most moisture and soap residue because they are closest to the shower area. If the buildup is light, lay the liner flat in the bathtub and clean it with warm water and mild detergent.
For more noticeable stains or soap scum along the bottom, sprinkle a small amount of baking soda on the damp surface and scrub gently with a soft sponge. Rinse the liner thoroughly so no cleaner is left behind. Then hang it back up fully open and let it air dry.
Avoid putting a plastic liner in a hot dryer. Heat can warp the material, create wrinkles, or shorten the life of the liner.
How to Remove Mildew from a Shower Curtain
If your shower curtain has mildew, start with warm water, mild detergent, and baking soda. The lower hem and seams are usually where buildup appears first, so pay extra attention to those areas.
For stubborn mildew, some materials may be safe to clean with diluted vinegar or a small amount of bleach, but only if the care label allows it. Never mix bleach with vinegar or ammonia-based cleaners, as this can create irritating fumes.
After removing mildew, drying matters just as much as cleaning. If the curtain is still damp and folded together, the musty smell can return quickly.
How to Keep a Shower Curtain Clean Longer
How quickly a shower curtain gets dirty often depends on bathroom ventilation and daily habits. After each shower, spread the curtain open so it can dry faster instead of leaving it bunched to one side.
If your bathroom has an exhaust fan, let it run for a while after bathing. If there is a window, opening it briefly can also help with airflow. When the bottom of the curtain stays wet, wiping it occasionally with a towel can make cleaning easier later.
If the liner has turned yellow, become stiff, or has mildew stains that will not come out, replacing it is usually more effective than repeatedly scrubbing it.
Do Bathroom Window Curtains Need Special Care Too?
If your bathroom has a window, the window curtains can also be affected by moisture. Bathroom window curtains should balance privacy, light, and easy care.
Light filtering curtains, privacy curtains, faux linen curtains, and short cafe curtains are often good choices for bathroom windows. They can soften the view from outside while still helping the room feel bright and comfortable.
If your bathroom window faces a street, a neighbor’s window, or an apartment walkway, custom-sized bathroom curtains may be a better fit. The right width and length can reduce gaps, create a cleaner look, and provide better privacy where you need it most.
Final Thoughts
Cleaning a shower curtain is less about using strong cleaners and more about regular care, thorough rinsing, and complete drying. Many fabric shower curtains can be machine washed on a gentle cycle, while plastic liners can often be cleaned with warm water, baking soda, and a soft sponge.
Keeping the bathroom ventilated and spreading the curtain open after each shower can also help reduce mildew and musty odors. And if your bathroom has a window, choosing the right privacy curtains or light filtering curtains can make the whole space feel cleaner, softer, and more comfortable.
