When you close, fill the drain with ice and pour sanitizer in the drain. If you do that for a week or so it should break down buildup deep in the pipes.

My SM taught us to pour a pitcher of Urnex down the drains to clean them! Just dissolve one packet Urnex in a steaming pitcher with hot water, pour, and repeat. Make sure you rinse the sink well after, you don’t want cross contamination. It works on ice bins as well, or any other clogs.
