This is my toothbrush, a couple of almost empty toothpaste tubes and an ashtray full of Sodium Bicarbonate, a.k.a Baking Soda.
The same person who told me to put the toothbrush upright, put all that Sodium Bicarbonate in an ashtray, not sure I like that idea.
Nevertheless, the idea is this; dry things have less germs, bacteria and creepy things. Mold needs water, and most other organizes need water, by simply putting the toothbrush in the sun, allowing it to dry, the majority of harmful type critters will die.
It is not that simple, but close, there are tons of purification systems that use the sun, or just get your toothbrush to dry.
I am now thinking, wrapping this up in toilet paper, soaking up the excess water and then placing in the glass would be better. I know she is right; putting it in the sink on the counter is not good. I have also been thinking about getting a toothbrush that is less fine and allows more space between bristles.
Ok, your right, this is a tip for the paranoid types, I suspect I will continue to drink the water, and put my toothbrush on the counter.
There really are paranoid people, and they may like this idea.
Note, I also have been thinking, take some toothpaste and smear on the counter, see if the Ants eat it, if so, there is a lot of sugar in the toothpaste and counter the idea of brushing.
