The Cardprotector housing is made of anodised aluminium, plastic and stainless steel. It is waterproof. We recommend that you clean it with a soft cloth and soap, then rinse it with warm water. Be sure to keep it away from sea water as the salt may damage the metals. If you come into contact with salt water, we recommend that you immediately rinse the case with fresh water. Be sure to dry the mechanism thoroughly before using it again.
Some cardholders Secrid are made of water-repellent leather and can be cleaned with a damp cloth. Non-water-repellent models, on the other hand, must be cleaned with a dry cloth.
