Off Your Head Cleanser
Fill a bowl or sink with luke warm water. Slowly dip the system into the water and leave for 5 minutes. Pump the shampoo onto both sides of the system and gently rub to clean off all adhesive.
Dip the system back into the bowl, apply more shampoo to the base if needed. Rinse under the tap to remove shampoo and loose adhesive.
Roll the system into kitchen roll and squeeze any excess water out.
