how do i clean my electactic beverage refrigerator? i don't want to ruin it.

Unplug it first. For the interior, use a solution of 2 tablespoons baking soda to one quart of warm water. Wipe shelves with a mild detergent. Clean the outside with warm water and mild liquid detergent. Never use steel wool, harsh chemicals, or flammable fluids on any part, especially the stainless steel.
