The diagnosis was spot on, each baking session makes the keyboard action a bit better.

A few years ago, I bought a nice-looking HP 32sII that was being sold for $10 as "broken" because someone had spilled an entire can of cola in it and just let it sit for months!

It took an entire Saturday of repeatedly performing the following cycle:

* 20 mins face down in ultrasonic bath of lukewarm distilled water
* gently shake out gunky water
* bake 2 hours in 150°F oven
* gently tap for maybe 10 minutes while astonishing amounts of brown powder came out
* clean the ultrasonic, replace with fresh water, and repeat again!

That slight mechanical agitation was key to getting all the gunk out.
I didn't stop until I could just tap-tap-tap and get NOTHING out.
I followed with one more baking session and let it sit overnight.

Here it is years later, it still works great, and is in my "daily driver" rotation.
