Take care to make sure everything is sterilized. If you skip this step, the peroxide may keep bubbling as it is killing germs, so make sure your utensils and the glass jar or bottle are very clean.

Important: If you are using a glass jar or bottle for storage and if the hydrogen peroxide (which is H2O2) continues to bubble, DO NOT screw on the lid tightly. Let the peroxide stop bubbling before tightening the lid.
