Keeping Drains Running Smoothly
For a great once-a-month drain cleaner, pour 1/2 cup baking soda into the drain, follow with 1/2 cup white vinegar -- it will foam. Cover and let sit 30 minutes and then flush with cool water.

For stubborn, slow-running drains, pour 1 cup baking soda and 1 cup salt down the drain. Follow this with 2 quarts boiling water. Let sit 30 minutes, then flush with cool water.
