Here's a great way to clean your household trash cans so that you know it's really clean. First empty your trash can. Rinse your trash can with water, either in the bathtub, sink or outside in the garden hose. Use a good disinfectant cleaner to wash it out and disinfect it. Be sure to let it sit on the can surface at least 5 minutes to do a good job of killing germs.Use a good stiff brush to scrub off any stuck on gunk and to get into the corners of the can. Rinse the can thoroughly and turn it upside down to drip dry. make sure the can is completely dry before you put anything in it otherwise it will start a new breeding ground for germs and smells because of the moistness.
