Pour a generous amount of plain white vinegar into a container and heat it slightly on the stove or in the microwave until it is warm, but not boiling. Warm liquid works faster than cold liquid at softening mineral bonds.

If your drain is horizontal or the vinegar drains away too quickly to soak the crust, soak old rags or paper towels in the warm vinegar and pack them tightly into the drain opening and around the affected areas.

To boost the cleaning action, you can follow the vinegar with plain baking soda. When the baking soda meets the acid, it creates a fizzing reaction that helps lift loosened particles out of microscopic crevices. Let the mixture sit undisturbed for at least an hour. For extremely stubborn, thick layers of calcium that have built up over many years, letting the vinegar sit overnight provides the necessary time for the acid to fully penetrate and soften the rock-like buildup.
