I was wondering if 99% IPA could be an issue to a screen, I am definitely an amateur at this but originally I was going to replace the joysticks and wanted to clean the console.

In a moment of carelessness I spilled IPA on the midframe assembly and some on the side, which seeped to the screen. I had accidentally doused the screen with a relatively small amount of IPA but I dried off what I could and turned on the screen successfully but there was a light colored splotch on the screen. After a couple of days the splotch on the screen is much smaller but it doesn’t seem like it will go away, is this permanent damage? I am wondering if it is possible to clean or fix this, if I get under the screen is it possible to clean, fix it or do I need a new LCD?

Thank you for any guidance in advance.
