Alright, my dishwasher and kitchen sink smell so so so bad. I researched it,
disassembled a bunch of parts and cleaned them (worst smell maybe in my life) a few months ago. It smells worse than ever.
Dishwasher is like 6-7 years old, disposal is like 12 years old. I kinda think I need to replace the disposal and all the pipes.
I'll ship the used disposal to anyone who gives me a reasonable solution.
