According to experts, you should replace your shower curtain liner every six months.
This recommendation is based on the fact that the lack of ventilation in a shower environment combined with high humidity creates conditions where mold and mildew can easily accumulate.
Why Replace Every Six Months?
As stated by Bowen in a reference from July 19, 2021, "Shower curtain liners should be replaced every six months, as the lack of ventilation and accumulation of humidity will cause mold and mildew." While cleaning can help, liners eventually degrade and harbor microbial growth that is difficult to eliminate entirely.
Tips to Prolong the Life of Your Shower Liner
Although regular replacement is advised, you can take steps to potentially extend your liner's life and keep it cleaner between replacements.
One suggested method from the reference is:
- Mix a solution of one part vinegar to four parts water in a spray bottle.
- Spray this solution directly onto the shower liner.
Regularly cleaning your liner with a vinegar solution can help inhibit mold and mildew growth, keeping it fresher for longer. Additionally, ensure your bathroom is well-ventilated by using a fan or opening a window after showering.
While these cleaning tips can maintain hygiene, the core recommendation for replacement remains every six months due to the inherent conditions that promote mold and mildew growth on the material over time.
