Heh. It's good to know I'm not the only one. (BF thinks -- and accurately so -- that I run on the paranoid side…)
95% of the labels are on WAY too well! I've scraped, pulled, soaked, used Goo Gone, you name it -- and still it's a time-consuming total p.i.t.a. to even get it gnawed up enough to preclude info procurement, let alone be satisfied with the thoroughness of the results.
But I can't
not do it. No way.
I have also done the bring-them-to-the-pharmacy-for-"recycling" thing. I'd still scrape off at least my name. I did that for quite awhile. Then just recently, I brought some in, and the person in the pharmacy confided that they don't
really recycle them. Duly noted, and back to the full-on label assault it was…
Raindropvampire, your idea intrigued me so much I ran straight off and tried it. (I used a hair blow drier.) Mine did not turn black, BUT the label became easy to peel off cleanly!

In very little time at all.
THANK YOU!!!

This will save untold hours…
