Start by making sure your disposer is turned off; run a hot stream of water (not directly into the disposer) for one minute, then reduce the stream to a small trickle. Insert one of the cleaning bags into the turned-off disposer with the small stream of water still flowing, turn on the disposer, then turn off the disposer once the blue foam disappears after 1-2 minutes, and give the sink a quick rinse.
Promising review: “Seeing is believing. Not only does it do a great job, but you can see it happening. It doesn’t just mask the smell and leave a lemon scent like some products; it cleans, too, and looks fun. Idk. Blue foam comes out, and that’s good enough for me.” —sylvie yah
