For as long as I can remember, every few months the garbage disposal would start to stink. I tried everything. You know, like grinding up egg shells, bleach, baking soda, etc. If it did wok, it would only be for a short time.

A couple of years ago I did a long search on the web for ideas. There were plenty, but nothing looked good. Kind of like people were making stuff up without knowing what they were talking about.

Then I ran onto a comment by someone who seemed to know what he was talking about. Now after a couple of years I can say that he did have the solution. The problem is that garbage gets stuck to the inside and is not washed off. Then rots.

SOLUTION:

Start water and disposal before pushing the garbage into the disposal.

Then letting the water and disposal run for 5 to 10 seconds after the garbage is ground up, washing the inside.
