Take the following steps to get the longest life out of a vinyl shower curtain: Stretch the curtain closed completely after a shower to eliminate folds where moisture cannot easily evaporate. Open the bathroom door and a window, if possible, after exiting the shower to allow steam to dissipate. Run the exhaust fan for five minutes following a shower. You can also wash your shower curtain in the washing machine. It works and keeps you from having to replace it and less garbage in landfills.
Fix slow drains. Pour half a cup of baking soda down the drain and follow it with half a cup of white vinegar. Let it sit for twenty minutes to a half hour, then pour boiling water down the drain (about two quarts). Every month pour boiling hot water down water drains to keep them from clogging or draining slow.
