@RubySoo Been giving this a lot of thought, because my bathroom is so small...and I have decided that storing toothbrushes upside down in a glass of everclear, and rinsing them before use, is the ultimate solution.
@RubySoo This is how barbers sterilize their scissors and combs...except they use a germicidal not safe to put in a human mouth. Everclear is 150 proof alcohol...a doctor could sterilize his instruments in it.
