iPhone XS Max A skin caused the glass back to develop a smudge patch

[alpi123]

I used a Slickwraps Naked skin for a month or so and when I removed it, there was this smudge on the back that cannot be removed no matter what I use. I tried rubbing alcohol, wet wipes, just microfiber cloth, and nothing helped.

Is this some kind of a coating that has been worn off or maybe a glue from the skin?

The weird thing is, whenever I wipe the glass with just a cloth, the patch doesn't seem to reveal itself but whenever I wipe the back with something wet, like a wet microfiber towel or wet wipes, that's when it gets revealed. Besides physically feeling the smudge all the time.

You may need to try some glass polish, or it could be a chemical reaction with the adhesive... hard to tell from the photo. Does it feel like it’s removed a coating or eaten into the back or is the mark on top of the rear glass?

My guess is that it's the oelophobic coating, but have no guess why it would be damaged from a skin.

Looks like it got too hot in that one spot. That is permanent damage.

I’d say the glass is permanently stained. There probably isn’t really much you can do, if you’re willing to go to the extreme, I would look at some car cleaning products that have detailing measures strictly for glass, but you take the risk of worsening it as well.

You can try applying stronger concentrations of alcohol (99%) and let it soak for a few minutes before rubbing it off.

Acetone is a stronger adhesive remover and safe to use on glass.

<shrug> Put a case on it, you're done. It's a phone, not a precious jewel.

For $1200 I better treat it like a jewel lol

but yeah, it's only visible when the glass is wet, so it's weird. I don't really mind it but I was searching for a way to fix it or at least know the cause of it.
