It’s important to clean and maintain your PDT device in order to guarantee its effectiveness and longevity. First, turn off and unplug the PDT device then use a soft, lint free cloth to wipe the outer part of the device to get rid of dust and debris. For the treatment area, where LEDs are mounted, it is necessary to use non-abrasive substances only to avoid damage. Proper maintenance will not only help to improve the efficiency of the device but also provides a clean experience with your skin. For more specific details, check the manufacturer’s recommendations for that particular model.
