How do you clean the rubber gasket that leads to the garbage disposal?

You can pour white vinegar down there and then some baking soda, the chemical reaction will clean out all the yuck.

The gasket I have on mine comes out and I clean it with an old toothbrush. See if yours pulls out, if not, just use a toothbrush on it the best you can. I also put baking soda and vinegar in my garbage disposal as it can really reek!

Vinegar & baking soda. I also throw lemon peels in the actual garbage disposal so it all smells fresh & clean.

1. Sprinkle a half cup of baking soda down the disposal then add one cup of white vinegar. The mixture will fizz and make a bit of noise, allow this to work for a few minutes while you boil a kettle of hot water. Pour boiling water down the drain.
2. Fill the drain with two cups of ice. Pour a cup of salt (rock salt is great if you have it, I improvised with coarse sea salt) over the ice cubes. Run the cold water and turn on the garbage disposal until the ice is gone. The ice/salt mixture will help loosen the grime and debris from the grinding elements

Cut a lemon or lime in half. With the water on and garbage disposal running, add the fruit halves, one at a time, to the disposal. The fruit will help clean and deodorize your drain.

Vinegar and baking soda is a great alternative to bleach!
