What does baking soda do together with hot water in your drain?

An additional effect is that unpleasant odors disappear and the drain smells fresh again. Chemistry expert Sander Oome of the RIVM notes that this combination causes less damage to your pipes than aggressive dishwashing detergents or plumbing products that sometimes contain chlorine.
