The shower curtain is one of those household items used daily but surprisingly rarely cleaned. While towels regularly end up in the washing machine and the shower itself gets scrubbed, the curtain often remains untouched. It gets plenty of water during each shower, making it an ideal spot for soap residue, lime, and moisture. myHOMEBOOK asked an expert how often it should be washed and what to consider.
Washing a shower curtain is usually simpler than you might think. The important thing is to do it. By following a few simple rules, you can keep it fresh and attractive for a long time.

Why Should You Wash the Shower Curtain?
After showering, the curtain appears clean at first glance. It gets constantly splashed and then dries again. But this combination of moisture and warmth makes it prone to deposits. Soap and shampoo residues can accumulate on the surface, along with lime from tap water, leading to unsightly discolorations over time.
The lower edge often shows how much accumulates there. This area stays moist longer and has less contact with air. As a result, mildew and mold can form. In short, the shower curtain is part of the bathroom and shouldn’t be completely ignored in the cleaning routine.
How Often Should You Wash the Shower Curtain?
There’s no fixed rule for every household. How often a shower curtain should be cleaned also depends on how often it’s used and “how well it’s rinsed after showering, meaning whether a lot of shower gel residue remains,” says Dr. Bernd Glassl from the German Cosmetic, Toiletry, Perfumery and Detergent Association (IKW). It’s also crucial whether the shower curtain can dry properly after showering.
If you pay attention to these things, washing the shower curtain every six to 12 months is sufficient. If you only consider cleaning it when visible stains have formed, you’re washing it too infrequently. Regular cleaning prevents deposits from becoming too entrenched. More important than washing is daily care. After showering, the curtain should be spread out as much as possible to dry quickly. When bunched up, moisture lingers in the folds.
Can the Shower Curtain Go in the Washing Machine?
For many fabric shower curtains, the answer is yes. However, the care label is always crucial. It indicates whether and at what temperature the curtain can be washed. Before washing, it’s also worth checking the rings or hooks. These should be removed unless they are explicitly allowed to be washed.

Shower curtains made of polyester or other washable textiles can often be cleaned in the machine at low temperatures. A gentle or easy-care program is often the right choice. Avoid very hot wash cycles unless the manufacturer explicitly allows them–especially for plastic or coated materials, as heat can damage the material.
If no washing instructions are available, Glassl recommends choosing a delicate wash program at a maximum of 30 degrees, setting a low spin speed, or at least turning off the final spin.
It’s also worth checking the manufacturer’s instructions for spinning. For delicate shower curtains, a lower spin program can be gentler. Then comes an important step that’s easily overlooked: hang the curtain back up immediately after washing so it can dry in full length.
What Can You Do About Mold or Mildew?
Small dark spots at the lower edge of the shower curtain are a typical warning sign. They can indicate mold or mildew. You shouldn’t just keep wiping over them; first, check whether the curtain can be cleaned according to the care instructions.
For washable curtains, a thorough wash can help. It’s crucial afterward that the curtain dries completely. If visible mold spots persist despite cleaning or the curtain can’t be adequately cleaned, replacing it might be the better option.
Important: Mold is not just a cosmetic issue. For larger or recurring mold problems, the cause should be examined–such as consistently high humidity or poor bathroom ventilation.

Common Mistakes to Avoid When Cleaning Your Shower
How to Keep the Shower Curtain Cleaner Longer
The best cleaning is the one that doesn’t have to become a major task. After each shower, the curtain should be pulled apart as much as possible. This allows air to reach the entire surface and water to evaporate faster. Regular ventilation also helps reduce moisture in the bathroom. Wiping down walls after showering further lowers the room’s overall moisture level.
The Shower Curtain Deserves More Attention
The shower curtain is a small detail in the bathroom–but one that comes into contact with water, soap, and moisture daily. Regular cleaning is a simple way to keep the bathroom more hygienic and well-maintained.
Remembering a monthly wash schedule, letting the curtain dry well after showering, and following the material’s care instructions will keep you on the safe side. And perhaps the shower curtain won’t end up on the to-do list only when the first stains appear.
