About saving those buttons, if the acetone doesn't work, take some steel wool and a scotch brite pad to em. It'll evenly scratch them up such that they'll "look" nicely diffused or frosted. Might be just the trick.
PL1:
Two of the lens caps were adhered to plungers.

Vise Grips made short work of pinching an edge and prying them apart.

One slightly cloudy lens cap cleaned up passably well with mineral spirits, but it's probably not worth the effort since a new cap/diffuser only costs $0.75 here.

Didn't even bother trying to clean the diffusers since they come with the lens caps.

The LEDs still look like total crap, but might be usable in a pinch, assuming the brightness isn't too badly degraded.   :dunno

The blue LED looked OK with the replacement diffuser, cap, and printed insert.

The plungers cleaned up well enough for reuse with just a bit of isopropyl and a thumbnail to break off a few bits of super glue.

Finally got around to trying Acetone and a Q-tip.

Before:


After:


The LEDs turned out OK with very little effort -- the red one looks almost new and only one or two of the others have a slight haze left on the face of the LED.

The lens covers did not fare well at all and the rough surface of the diffusers makes them very difficult to clean -- given that these are sold together here it's probably not worth the effort on these.

Here I thought it would be a tutorial on how to zoom into a 20x20 pixel image and suddenly have a hi-rez 20000x12000 image that shows the killer.  I'm rather disappointed.

Yeah, I though we were doing Crime Scene Investigation stuff here too. That or a CSI PC game. I know nothing of these "fingerprinting machines".
