I wouldn't put your toothbrush in the dishwasher or boil it. Both reach temperatures that can do damage to the bristles. Listerine is a good option. Sonicare has released a new toothbrush that comes with an ultraviolet light sanitizer compartment on it. So stick the toothbrush head in push the button and 10 min later completely sanitized. Maybe you should consider that instead.
Consider boiling them or running them through your dishwasher.
I don't know about that, but you can just use rubbing alcohol and a toothbrush.
A dry toothbrush is already frozen, that is, solid. It becomes solid well above 100 Celsius, the boiling point of water. If the toothbrush gets too cold, near -40C, it may become "brittle" and snap. Of course if you store the toothbrush "wet" the water on the bristles will freeze near 0C, but will melt quickly under water.
Locate the screw in the center of the blades. Unscrew and remove blades, once removed they can be cleaned and disinfected in boiling water.
what is the difference between freezing and boiling point
difference between critical temp and boiling point
Boiling Point Elevation
The difference between the freezing and boiling points vary from substance to substance.
The difference between them is that boiling is when you heat a liguid and it turns into a gas, vaporization is when a liquid changes into a gas and evaporation occurs at the surface of a liquid beneath its boiling point.
When you steam the lobster, it is placed in a basket above a pot of boiling water. When you are boiling the lobster, it is placed directly into the boiling water.
Heating almost to boiling means that the liquid doesn't boil. Heating just to boiling means the liquid boils.
It's freezing point is between 0 to (-1) *c& boiling point is between 103 to 105*c
