Clean Shower Curtain. Fill up your bathtub with warm water and mix in some washing powder biological leave the shower curtain to soak in there for an hour or so. Check specific instructions for cleaning for your shower curtain.

Dilute some white or apple cider vinegar in a bucket or plugged sink and let the rings soak in the mixture for 15 to 20 minutes or longer. For them you may need to tumble dry at first and iron afterward. Next use the cloth to lightly scrub the curtain to remove the dirt and grime.
Just as important as cleaning the shower curtain is cleaning what it s hanging from.
But there are some curtains built of heavy natural fibers. You can now use a scrubbing brush or a toothbrush to scrub away anything that is on there. Always use warm water for the best clean. Flip the shower curtain and repeat.
