Garbage Disposal Smell

[mattl]

One other possibility is a block vent stack.  If the vent going up through the roof is blocked the sewer gasses may travel up the drain line, you may get a smell if the trap is draining completely - which it's not supposed to do -- sometimes a blocked vent can cause that when for example a toilet is flushed.

 

A relative had an issue with a vent, a squirrel crawled in, or fell in and died, bad situation to resolve.

round toilet brush

I bought a round toilet brush at Walmart that will just fit through the opening of my ISE/Kenmore with stainless chamber.  A little Comet on the brush, stick it in and scrub around.  When I pull the brush out it reverses the rubber baffle and scrubs it too.  I sometimes still take a paper towel with comet and reach up under the "rim" so to speak and scrub it by hand (far away from the grinder).  Usually a gallon of hot water with bleach in it poured down while running is all I need.  Mother's old Kenmore was rusted like that inside and it also stank.  Replaced it with a stainless chambered one and no troubles since.

Taa Daa the smell is gone.

Had some extra time yesterday. Kept thinking about it. I did 3 full sink power purges in a row. Well with a large rectangular deep sink I discovered it takes over 15 minutes to get the sink 3/4 filled. Damn low flow faucets. Did it with warm water and a couple of squirts with Dawn. After the 3rd purge it did not smell except for the rubber insert. Soaked that in Dawn and water in a dish. Put that into the dishwasher last night and ran it. Did not have and odor to it this morning. Did another power purge this morning. No smell. Put the rubber back in place and left it to go back to the other house this morning. Will be back down Wednesday night to see. I think the problem has been solved hopefully. I wasn't doing such a large purge before. Thanks for all your suggestions. The plumbing is correct under the sink with all the correct angles.
