You should clean your OG with mild soap and water, or a silicone-safe sex toy cleaner both before and after usage. The OG is waterproof, therefore you can simply run it under water. Wipe it dry with a cloth or paper towels and store it in a cool, dry location. (Do not put the OG under any extreme conditions, ie boiling, harsh detergents, etcetera. Doing so may result in permanent damage to your sucking vibrator.)
