Yesterday, I was ridiculed for admitting on B105 that I cleanse my toothbrush in the dishwasher! What's wrong with that? You wash silverware in a dishwasher and that goes in your mouth. Not to shock you further, but I also wash the toothbrush holder in the dishwasher. What better way to kill germs, especially after a bout with strep throat, the flu, or a cold.
