I buy a heavy duty shower curtain, so when it gets dirty I throw it in the washing maching with my towels in hot water with a little bleach. Put the load in the dryer but be sure to only leave the shower cutain in for 5 to 8 minutes ( depending how hot you have your setting). The shower curtain comes out pliable and clean as a whistle! Hang it right up again and enjoy the sparkle!!
