I typically tell my clients to buy a toilet brush, and of course ONLY use it for the disposal flap. If you start smelling a yucky smell from the sink area it is typically the gunk under the flap.

The removable flap does stop the "Heebie Jeebies" and of course for liability reasons I tell folks never to do that, but if it is not on...there are other ways to clean this area, many on the internet. Running it for 30 seconds longer than you think will also help.
