Whatever you do, do not put any of our toothbrushes or travel cases in the dishwasher. It won't be pretty.
The high temperature of a dishwasher, boiling water, or microwave will melt the plastic. To sanitize your toothbrush we recommend using a solution of 50/50 hydrogen peroxide and water. You can use the 3% dilution of hydrogen peroxide, which is the most common and typically found in drugstores or pharmacies. Soak your toothbrush for 5-10 minutes and voilà! Good as new.
