Disinfect the Trash Can
It sounds counterintuitive, but your trash bin needs to be disinfected. Every few weeks, after emptying the trash, I bring the bin outside and spray the inside with Clorox® Clean-Up® Cleaner + Bleach, then let it sit in the sun. The sunlight combined with the cleaning solution will completely disinfect any bacteria and eliminate strong odors. After five minutes, I rinse, wipe, and let dry.
