iPhone 17 aluminum frame shows discoloration near charging port and camera button

Hello, last month I bought an iPhone 17 Mist Blue, and recently the aluminum frame started to discolor around the charging port and Camera Button. The color is going from a nice blue to a pink, and I’m not sure what caused it. I’ve always used it with a transparent case and don’t use any harsh chemicals to clean the phone. What do I do?

Do Not Scrub the Frame: Avoid using abrasive materials, heavy-duty cleaners, bleach, or hydrogen peroxide. These will further damage the clear sealant and potentially worsen the discoloration. 

Document the Discoloration: Take clear, well-lit photos of the pink areas next to the unaffected blue portions of the frame to serve as proof. 

Contact Apple Support Directly: Schedule an appointment at an Apple Store or contact Apple Support.

Most of the times apple will see this as cosmetical damage that is not covered under warranty I am afraid, but always have it looked after to confirm or deny that

Plasticizers and other additives can migrate out of some flexible plastics, especially soft TPU, or poorly formulated silicone cases. With warmth, pressure, skin oils, moisture, and long contact time, that material can leave a film or stain like transfer on the anodized frame. Often the “discoloration” is removable residue rather than damage to the anodizing itself.


Use water and a damp cloth or a microfiber cloth to clean the surface.
