Clean your issa toothbrush after each use by washing the brush with warm water while running your fingers through the bristles. Allow your toothbrush to air dry. If you find any blood on the brush surface, please clean the device with soap and water. NOTE: We do not recommend placing issa 4 plus in a UV sanitation case. Never use cleaning products containing alcohol, petrol or acetone. For optimal hygiene, we recommend spraying the body of the toothbrush with FOREO Silicone Cleaning Spray once a week, and rinsing with warm water, replace brush head every 6 months
