OK to leave some "gunk" on front display edges before reattaching?

I’m putting my iPad Air back together after having replaced the battery, following guide 25869. I’m at the point where very shortly I will be re-attaching the front display (the piece of clear glass, a.ka. “screen” or “digitizer”), then re-attaching the LCD, then putting the pre-cut adhesive onto the frame so I can press the front display back into place.

The frame is quite clean - no black adhesive tape; I am down to bare metal on the edges where the new tape will go. The front display (the glass) is also clear of tape on its edges - however those edges still have a very thin, very spotty layer of black "gunk,” i.e. adhesive residue. The instructions say to “clean the remains of the adhesive” from the glass with isopropyl alcohol - but I am finding this simply doesn’t do the trick, given I am restricted to plastic scraping tools if I wish to avoid doing damage. An alternative would be to buy a new front display, but at $39.99 from iFixit that’s pretty steep for replacing a part that is not actually broken.

My limited experience w/ iFixit repairs (I’ve worked on a couple of Macbooks & an iPod) tells me that as long as the gunk is merely a very thin layer, and is itself clinging quite tenaciously to the glass, that this ought to be good enough for the new adhesive to adhere. However, there is another aspect: would there be any chance that a minuscule increase in spacing between glass & LCD would interfere with touchscreen function?

I guess I could go ahead & see; and if there were interference w/ the touchscreen, I could shrug, buy the new front display, & do a follow-up procedure to install it. At least it would be simpler than the full battery replacement procedure I just went through.

For those of you w/ lots of experience fixing tablets etc., what do you think?

If you have a big blob of that “gunk” (or should I say adhesive) under your display, you may possibly have trouble with your display, damage nearby components, or make repairs harder. I recommend a thin layer of adhesive.

There are no big blobs - I have done enough scraping (even if I can't get it all off) so that the remaining gunk is quite thin.

I think what I'm really asking is, must the surface be squeaky-clean - no residue at all - or is a very thin layer of residue, obviously much thinner than the original adhesive tape when it was intact, acceptable as it is?

It's ok to leave some thin layers of adhesive residue on glass, provided the new adhesive is tacky enough to hold the glass in place.

Personally, I would buy a new digitizer though - you can get it for $15 elsewhere

You can leave residue on the sides. This will not affect the display.

Sammy Zhang, thanks for letting me know about the lower-priced part availability. I'm a little leery however when I see reviews for some of the $15 to $18 displays available via Amazon - always hard to know for sure, but quite a few reviewers complaining of quality issues. Maybe I'll try re-attaching the original & see how I do; if problems, then I can decide which price point to choose when buying a replacement part.

I use Goof Off to finish removing the last bits of adhesive. The display will lay down better.
