You are about to take a nice relaxing shower, then the pull of the shower curtain sends screeching decibels to your ears. Not to mention, now, you’ve wakened the entire family! Stop the piercing sound by coating your shower rod with car wax. Apply 2 tablespoons with a soft dry cloth and buff. The silicone and wax in the polish will have formed a slick invisible coating that will allow a silent entrance and exit from the shower!
