It pays to have a clean garbage disposal

It didn't take long to zero in on the source -- the garbage disposal.
Then I did a search on the Internet, found a variety of suggestions, and felt pretty sure that I'd have to call a plumber because they all seemed to assume skills and/or tools I didn't have. Instead I tried a very simple idea and amazingly it worked.
3. With the water running put one hand on the stopper and the other on the switch, as you pull out the stopper, turn on the switch. (Be sure to do it in that order, to keep your hand from getting chopped up!)
The reason this works is that junk gets stuck on the walls of the drain, and since it's garbage, it rots and stinks. By immersing it in soapy water, the junk gets dislodged and goes down the drain and out of your life.
