I can give you the most accurate information about how to sanitize a toothbrush.
assistant
Okay, thanks.  Tell me how.

Did you want to sanitize the brush or the handle?
assistant
All of it.

Your toothbrush’s effectiveness depends on all parts being completely sanitized.  The bristles should be properly disinfected and the handle shouldn’t have any trace of bacteria or toxic chemicals, so I’ll give you details for each.  Since you asked about the toothbrush, I’ll give you a more detailed answer about that, but the basic technique is the same.
