i’m sure someone will probably complain that i usede the term “germs” and was kinda vague, but here’s my question:
temperature-wise, where’s the line between heat that breeds germs and heat that kills them?
It depends on the particular bug you are referring to, but for most, about 180 [sup]o[/sup]F is lethal. On the other hand there are some bacteria living in deep ocean thermal vents in temperatures exceeding 300 [sup]o[/sup]F.
okay. the reason i posted this is my toothbrush got dropped on the counter, and as i was running hot water (as hot as it goes, but probaqbly not 180) over it, i thought “gee, i hope i’m not making it worse.” i would’ve put rubbing alcohol on it, but i didn’t think that would taste very good.
You could always boil it, if you’re that concerned about germs. That’s ~212 [sup]o[/sup]F right there, assuming the toothbrush will handle the temp without melting.
Soak it in a mouthwash with alcohol in it. Minty.
The threshold for keeping food safely is 140 degrees F. I doubt that your water heater is set that high… most are around 120-130 F. How about using the mouthwash on yourself tonight, and getting another toothbrush tomorrow?
You dropped your toothbrush on the counter? Hell, I keep my toothbrush on the counter. Unless you live in a bubble (or an absolute pigsty), you’ll be fine.
Hmmm, I responded to a duplicate post in a parallel thread.
You dropped it on the counter and you’re worried about germs? What germs are on your counter that aren’t likely to be on your toothbrush already? I assume you mean bathroom counter–a kitchen counter can have all kinds of food-borne nasties.
Just wash it with soap and hot water, that’ll kill most anything that you would need to worry about. And warm temperatures in your toothbrush will probably do little to foster bacteria growth since there’s not a lot of nutrients in there (unlike, say, a chicken breast).
I dip my toothbrush in Listerine like once every 2 weeks to kill anything in there. And I seem to get a better brush out of it that way, so that’s just a bonus.
Nametag nailed it. The paranoia about microbes that exists these days is stunning. In fact, some people believe that this paranoia has led to an increased incidence of:

B. Atopic disease- http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=12642824&dopt=Abstract
Unless you are culturing H. pylori on your bathroom counter, your toothbrush is fine.
