Apple products are made with a variety of materials, and each product might have specific cleaning requirements which vary by the part you're cleaning. To get started, here are some tips that apply to all products:

• Use only a soft, lint-free cloth. Avoid abrasive cloths, towels, paper towels, and similar items that might cause damage.
• Unplug all external power sources, devices, and cables.
• Keep liquids away from the product.
• Don't get moisture into any openings.
• Don't use aerosol sprays, solvents, or abrasives.
• Don't spray cleaners directly onto the item.

If liquid makes its way inside your Apple product, get help from an Apple Authorized Service Provider or Apple Retail Store as soon as possible. Liquid damage isn't covered under the Apple product warranty or AppleCare Protection Plans, but you may have rights under consumer law. If you plan to visit an Apple Retail store, make a reservation at the Genius Bar (available only in some countries and regions).
