Step 1: Remove the hair from your brush as you would for The Quick Sanitize.
Step 2: Fill a bowl with warm water and a few drops of natural shampoo and dip your hairbrush into the soapy water, swirling the brush around to ensure that all bristles are coated. Be sure not to submerge the hairbrush as it may cause damage to the base and handle.
Step 3: Take a clean, unused toothbrush, wet it, and put few drops of the natural shampoo on top. Using the toothbrush, clean around the bristles and the surface of the hairbrush.
Step 4: Rinse off your brush with clean water and shake off excess water. Spray your hairbrush with a sanitizer of your choice and place bristle down overnight on a towel to dry.
