How should I clean the inside of my refrigerator?

Unplug the refrigerator, then hand wash, rinse, and dry removable parts and interior surfaces using a clean sponge or soft cloth with mild detergent in warm water. Do not use abrasive or harsh cleaners such as window sprays, scouring cleansers, flammable fluids, bleaches, or cleansers containing petroleum products on plastic parts, interior liners, or gaskets. Clean both sections about once a month to prevent odors from building up. (Page 6)
