How do I clean and maintain the exterior and interior of my dishwasher?

For a standard exterior, use a soft damp cloth and liquid spray cleaner, and avoid abrasive powders or pads. For a stainless steel exterior, use a soft cloth with mild detergent and water, white vinegar and water, or a multi-surface cleaner — never use products containing chlorine bleach or citric acid. For the interior, wipe with a soft cloth or damp sponge, and switch to a chlorine-based dishwasher detergent if you notice discoloration or tomato-based stains.
