Saline sensors should only be subjected to saltwater while they are in use. After use, you must rinse the sensors with clean water to remove the salty residue. Doing this will prolong the life of the sensors. After rinsing, dry the sensors with a towel or tissue.
Do not leave the sensor felts in the saline sensors. Leaving wet sensor felts in the saline sensors will corrode them. Store used sensor felts separately from unused ones.
You can purchase replacement sensor felt packs from the EMOTIV online store.
