User level: Level 1 (8 points)Hi, yesterday I noticed some oxidation/rust on the screws on the bottom of my Apple Watch Ultra 2. Is this a problem? Is there anything I can do about it, and could it affect anything?

I think the only problem might occur when a technician tries to remove the screws, say to replace a battery in the future. They probably will still be able to do it, however.
The oxidation stems from exposure to moisture or various chemicals (sunscreen, choline, salt water, moisture, sweat, lotions, soap, shampoo ...even air pollution). So always wipe it gently with a damp microfiber cloth after any such exposure, but at least daily in any case. It should be wiped clean each day (gently) just from skin exposure. I never swim nor shower with my watch on for these reasons.
