Alternatives to Vinyl Shower Curtain Liners (and a Water-Repelling Tip) Great ideas for using something other than vinyl for shower curtain liner. I decided on using two polyester ones, one for inside, one out.
Put shower liner in washing machine with some white towels, regular detergent, and 1 cup of vinegar. Vinegar will remove the soap scum! Run through a cycle with warm water. When done, hang it back up on the shower curtain rod to dry.
