I can give you the most accurate information about how to sanitize a toothbrush.
assistant
Okay, thanks.  Tell me how.
user
Did you want to sanitize the brush or the handle?
assistant
All of it.
user
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.

What is it?
user
You’ll want to disinfect the bristles with 70% isopropyl alcohol, which can be found at a drug store.  This is the exact same stuff that dentists use.  Soak the brush in it, then flush it with a little water, then soak it again.  Your toothbrush should now be extremely clean.  You’ll also want to throw out the original brush and handle, as well as all the packaging and other materials that came with it.  Clean them with 70% alcohol as well.  If they’re from a store, there’s a good chance they’re contaminated with bacteria from the floor or the hands of the last person who used it, which means you’re much more likely to get sick from them.
assistant
Thanks, I will definitely get some alcohol next.
