iPhone 17 Pro’s Cosmic Orange Finish Resists Everyday Cleaners, Tests Reveal
In late 2025, reports emerged from iPhone 17 Pro users claiming that the Cosmic Orange variant of the device was exhibiting an unexpected color shift to pink or rose gold hues. These accounts, primarily originating from Reddit, raised concerns about the durability and resilience of the phone’s anodized aluminum finish.
Apple’s Cleaning Guidelines and Potential Causes
Apple has long provided specific cleaning instructions for its devices to maintain their appearance and functionality. The company advises against using products containing bleach or hydrogen peroxide, emphasizing the importance of avoiding moisture in openings and recommending the use of a soft, slightly damp, lint-free cloth for cleaning. Hydrogen peroxide, known for its strong oxidizing properties, can potentially alter the coloration of anodized aluminum surfaces, leading to discoloration if used improperly.
Investigative Testing by CNET
To address these user concerns, Andrew Lanxon from CNET conducted a series of tests to determine the impact of prohibited cleaning agents on the iPhone 17 Pro’s finish. Lanxon applied an oxy-active stain remover containing oxygen-based bleaching agents and household bleach to the device’s metal sides and camera bar over a three-month period. Each application involved leaving the chemicals on the surface for up to an hour before cleaning.
Despite this prolonged exposure to harsh chemicals, the Cosmic Orange finish remained unchanged. Lanxon noted that even after several months, there was no notable difference in the device’s coloration. He mentioned that under certain lighting conditions and with a squint, a slight shift might be perceived, but he admitted this could be subjective.
Understanding the Color Shift Phenomenon
The findings suggest that the reported color changes are unlikely to result from everyday cleaning practices. Instead, the perceived shift to pink or rose gold hues may be attributed to lighting conditions and the phenomenon of metamerism, where colors appear differently under various light sources. For instance, under cool, bright lighting, the Cosmic Orange finish might reflect light in a way that gives it a pinkish appearance, while under warmer lighting, it retains its deep orange hue.
Durability of the iPhone 17 Pro’s Finish
The iPhone 17 Pro’s anodized aluminum finish has been a topic of discussion regarding its durability. While the device’s design is visually striking, some users have reported that the sharp edges, particularly around the camera bump, are prone to scuffing and chipping. This is due to the high-pressure contact points created by the design, which can lead to the anodized coating chipping away, revealing the aluminum beneath.
Preventive Measures for Users
To maintain the pristine appearance of the iPhone 17 Pro, users are advised to follow Apple’s cleaning guidelines diligently. Avoiding harsh chemicals and using recommended cleaning methods can prevent potential discoloration. Additionally, using protective cases, especially those with raised edges around the camera, can help shield vulnerable areas from scuffs and chips. For those who prefer a caseless experience, being mindful of handling and avoiding placing the device on abrasive surfaces can also help preserve its finish.
Conclusion
The iPhone 17 Pro’s Cosmic Orange finish demonstrates resilience against everyday cleaning agents, as evidenced by controlled testing. While certain lighting conditions may cause the color to appear differently, this is a temporary optical effect rather than a permanent discoloration. By adhering to recommended cleaning practices and taking preventive measures, users can ensure their device maintains its aesthetic appeal over time.
