Before you reach for that heavy-duty, chemical-smelling bottle of drain cleaner (and before you call an expensive plumber), look in your pantry. The solution to your problem is likely sitting right next to the flour and sugar:
Mix a 3:1 ratio of bicarb to water (e.g., 3/4 cup bicarb, 1/4 cup water) to make a paste. Smear this paste all over the inside of your drain and the sink strainer.

This pressure helps to dislodge sticky grime from the walls of the drain without melting your pipes or poisoning the water table. This is the most effective natural drain cleaner on the planet.
