Here was my go at it.
Did a few trials and used the famous salad spinner with fake TSP from Lundmark in the Kendal Commercial Grade 9 Liters 540 Watts HEATED ULTRASONIC CLEANER HB-49MHT. Set it to about 35 degrees C. No pre-soak due to some reports of excessive fading
Mostly did 40 chips at a time, but did a few with 60 and saw no diminished effects.

Had the Macallan 10 to keep me going... (also no diminished effects)
Bottom row: dirty chips
2nd from bottom: 60 seconds in cleaner. Still had some few chips with tiny bit of gunk/HJ in the deep grooves
3rd from bottom: 90 seconds in cleaner. I did not see a noticeable difference from 60 seconds, so did the rest at 60 seconds or less and added a light brushing with toothbrush in TSP solution immediately after removing from the machine
Top row: 1 min in cleaner + light brush with tooth brush in TSP solution to get the deeper gunk/HJ out of the grooves. Pristine.
Same order as above from right to left
45 seconds for the snappers so as not to fade. Fear was unwarranted, I think. Minimal residual gunk/HJ after the machine. Still brushed every chip lightly due to OCD
$5s
Top rown un-clean
Bottom: 60 seconds in machine and dried. Came out looking great. Slight appearance of fading, which I attribute to washing away gunk/hooker juice and am personally ok with because I think this is actually more natural clay color of the mint chips (as others have also proposed)
For example. Top row is cleaned. Bottom row uncleaned. The left-most 2 chips on bottom row are uncleaned, but look to be the "newest chips" with sharp edges, and also noticeably lighter than the other unclean chips, which are more used. Right?
Goodbye hooker juice. Until next time...
