Cinnamon for smelly drains! I discovered I had a sulfur-smelling kitchen sink drain when I moved into a new apartment -- it was a strong smell that would spread through the house! Tried repeated treatments of pouring baking soda into the drain, then washing it down with vinegar, then rinsing with hot water 30 minutes later. It helped some, but not enough. By accident, I discovered that true cinnamon powder would fix the problem. I had spilled about a half cup of cinnamon into that sink and simply rinsed it down the drain with enough water to avoid clogging the drain. The drain smelled fresh the next day and every day after. Cinnamon acts as a natural antibiotic. It saved me from having to bring in a plumber.
