Clean garbage disposal. Run hot water through disposal for a minute. Pour 1/4 c. baking soda. Flip disposal on for 2 sec., just to whirl the baking soda inside, then leave it alone for 10-15 min. Follow with 1 c. of vinegar. Watch the bubbles erupt out of your drain. (Yay!) Rinse through one last time with very hot water and run disposal for 5 sec.
