Green Housekeeping Tip #1: Vinegar is your friend. 1. Let your dirty paint brushes soak in warm water with vinegar to break through the dried paint for easy cleaning. 2. For clogged drains, pour a tablespoon or two of vinegar into the drain and let sit for 30 minutes, then rinse with water. 3. Vinegar with a pinch of salt works great to clean lime deposits off of shower heads and faucets.
