I've had lots of success using the Salon Care 40 cream, with nothing else

Here's a before / after of a 1988 vintage KeyTronic keyboard case I did. It
took 2 treatments, at about 45 minutes each.


I applied the cream, covered in plastic wrap, and let it sit in the sun.
Every 15 minutes I went out and massaged the plastic.

For the keycaps I used the 40 clear liquid, cut it with a little bit of
water, added a spritz of Oxy Clean, and put it all in a clear plastic
container. I stirred the keycaps every 15 minutes. This took much longer,
about 8 hours (the keycaps were PBT not ABS like the case). Both came out
(no, the keys are not the same color as the case. The keycaps are "Sea
Mist" and the case is "Driftwood" according to the owner's manual)

I'm working on editing a video together of how I did the keyboard. My one
tip is to go slow. You can always do another treatment. Check frequently.
If you think you're anywhere near close stop, wash the item, and let it
dry. Give it a good look. Then check if it needs another go. Also wear
gloves. The Salon 40 will give you chemical burns!

One final tidbit: Be extra careful with brown / tan plastic (like old Apple
keycaps). They can "burn" *very* easily.
