2. Dry out your brush
A brush that stays wet breeds bacteria. If you can, take your toothbrush out of its travel case as soon as you reach your destination. Standing your brush upright in a cup will allow the water to drain away from the bristles. (Just make sure it’s not kept where the maid could knock it into the toilet!) If you’re traveling by car, you might let your brush air out on the dash. Take your toothbrush out of its travel container as soon as you get home.
