Instead of throwing away your vinyl shower curtain when it starts to get moldy or slimy, try washing it in your washing machine first. Toss it in your washing machine with 2 bath towels and a cup of vinegar, the spin cycle will probably ruin it so make sure to remove it before the spin cycle starts. If you just want to replace your shower curtain, don't throw away the old one, wash it first then repurpose it as a drop cloth for painting or put it under the kids craft table to protect your carpet or flooring. Use it as a tarp or to line the trunk of your car, cut it into smaller pieces and use it to line the bottom of cabinets or drawers. Get creative, I'm sure there are a million other uses and you can feel good that it's not just sitting in a landfill somewhere.
