1. Citrus Scent
Gather a couple citrus such as lemons, grapefruit, or oranges. You can choose your scent! I prefer the grapefruit. Cut into thin slices. About 3/4" to 1" thick. Grind the slices one at a time in the garbage disposal. Do not jam all the slices into the garbage disposal at the same time. You will run the risk of clogging your pipes. Rinse with hot water.
2. Disinfectant
1/4 cup Borax is all the disinfectant you will need. Every two weeks or so pour some borax into the garbage disposal.
Garbage Pail Deodorization can be fun! Each time you add garbage to your garbage pail, sprinkle a handful of baking soda on top to help control the malodor. In addition, when you change the garbage bag sprinkle some in the bottom of the pail before replacing the garbage bag.
