How can I get rid of the sour odor in my garbage disposal?

Abrasion is the key to removing the biofilm.

Buy a couple of different long handled brushes from the dollar store, including a toilet cleaning brush.

Windows open, Saturate the brush with Lyme Away and try to scrub the sides and up under the rim of the disposal. When you pull out the brush do not splatter yourself. Yuck.

The run lots of hot water and if you’ve a sprayer wand, try to get water in there at an angle, with the brush out. Run the disposal, rinse more.

Then try a citrus cleaner and a different shaped brush. Repeat the rinsing process.

Vinegar & soap is another option.

They key is to chemically shock the biofilm colonies.

Thow Away the $3 of brushes, when done.

Clean with dawn soap and ammonia. It will get rid of any smell you may have in there. Here is what I use most of the time for everything. https://bushraslifestyle.com/diy-cleaning-caddy/ but to get rid of really awe-full smell I do add ammonia.

Hope it helps! Bushra

I always grind up my orange peel in the garbage disposal and in between I put baking soda in there. I have also ground lemon peels and apple cores and/or the peeling from applies. The baking soda seems to help a great deal in between grinding the different fruit peels.
