You can clean the chamois pockets with Dial liquid antibacterial soap, making sure to rinse the chamois pockets well. You should clean the pockets after each patient/client. You can leave the pockets wet from the water after rinsing for the next client/patient or purchase extra pockets to use. The cross straps can also be washed with Dial liquid antibacterial soap. However, if you are doing brain mapping, specifically a qEEG, you need to have the headband and cross strap perfectly dry before using again.
