To prevent clogs and deodorize sink drains, reach for a box of regular salt. Pour 1/2 cup of salt (coarse salt works best) down the drain, then pour very hot water after it. The salt will act as a corrosive to scrub the drain walls, and the hot water will help flush clogs down the drain while dissolving the salt. This process also naturally deodorizes, so any foul odors will be neutralized, leaving your drain clean and smelling more fresh.
