I replaced a battery of this rMBP late 2012. After pouring 91% isopropyl alcohol to dissolve the adhesive I freaked out to see that it went through the keyboard and managed to seep into the screen. Can this vapor away?

That is a shame to see.
91% alcohol still has water in it and now it also has dissolved adhesives.
Unfortunately I don’t see how the situation can improve.

Most likely, it will mostly evaporate, but it will not end up perfect.

Many years ago, a girlfriend submerged her Powerbook in mountain dew for a few hours, amazingly the machine still worked, with the biggest problem that the screen looked mostly like this ... After a couple of weeks, there was only a little bit of mountain dew still under her screen.

Isopropyl usually evaporates pretty instantly, as it's alcohol. How long has it been like that? It may have damaged the LCD more than be liquid remaining. I'd take it apart and have a ganders.

Most of it will evaporate within few days, but don't think it will look good.

Happened with my Asus gaming laptop when i was cleaning the display. It evaporated but left an ugly spot which became an eye sore.

If it is in warranty or you have apple care, definitely get the display replaced.

Unfortunately I am a hobbyist refurbisher, and this is my first rMBP. I followed a tip on iFixit to remove the battery by soaking it in alcohol, but I honestly didn't think of the seeping...

Was this you?

I used isopropyl alcohol and it drained back my display - now I have a lot of wet spots. Protect your display if you doing this job !!!

Tips how to solve this new problem ?"

I think you could wait a few days but honestly I'm saying it's had it. Take it as an expensive lesson, and warn others. Isopropyl is a fantastic chemical but it is a liquid and will pour through surfaces, the guide on iFixit states using a few ML at a time I'm assuming for this reason. I don't think there's going to be a great deal you can do to solve the problem as chances are the chemical has corroded through or between the filter layers in the IPS panel. You could try taking it entirely apart but it's not going to be an easy task, may be worth a shot. I don't think it's going to clear by itself though and it's probably doing more damage the longer it's left in there.

Haha no it's just a way to say that I learned my lesson and know what to do next time.
Good good, we all make mistakes, if you're not making mistakes you're not learning!

I fried a PS2 motherboard and overtightened the head bolts on a car in my more formative years, excrement happens!

:cool:
