Baking soda can work wonders at preventing odors in your trash cans. Sprinkle it in the bottom of a trash can or directly into the trash to help absorb stinky odors. As a bonus, baking soda is great for scrubbing out your trash can to remove odors that may have seeped into it. This is often a number one product to keep trash cans less stinky.

It's simple: add 1/4 cup of baking soda to the can in the morning. By the evening when the trash is ready to be taken outside, no odors will be evident. When it's time to clean out the trash cans themselves, leave 1 cup of baking soda in the bottom of the can after they have been washed and dried. This can help absorb moisture and odor until next week when you clean the cans out again.
