Display of iPhone 8 plus has gray stain

Hi there, so this is kind of a long story. I was replacing the ear speaker on my iphone 8 plus and there was a lot of dirt in the grills so i cleaned it with this liquid especially for the cleaning of electronics and unfortunately some of the liquid got trapped between the display. It was a lighter stain that you could see mostly on a white surface from a 40 degree angle. I then used a hairdryer to dry the liquid out and after that it went back a little bit but I noticed a gray stain, which was much more visible that the white stains. Is that just a coincidence or did I damage the display with the heat? Honestly the latter seems unlikely as it's only a small spot, not the whole side of the device I heated. But I googled and didn't find a cause. There are two photos attached, one from the top and one from a 40 degree angle where you can still see the white residue of the liquid. Also, at an angle the gray spot turns bright as you can see.

Thank you so much in advance :)

Best regards,

Unfortunately, you got the spray between the multiple layers of the screen assembly. Depending on the composition of the spray, it may dry off and leave little to no residue (for example, mostly IPA) but if there are cleaners, it will probably leave a residue that will be visible.

Let it dry for a day or so to see if it gets noticeably better. If it doesn’t, you will have to replace the screen.

Thanks so much, it's noticeably better today so hopefully it'll disappear in a week or two. The solution is just rubbing alcohol in a gas can I think, so it should evaporate.


Has the stain disappeared ?



I have the same problem after battery replacement ? Maybe it could be a gap by applying pressure to remove the screen with the suction cup ?
