Right tool for the job, right?
I got into Tarn-X for cases like this. Not a great picture of the Z80 in the socket, but you can kinda see how all the legs are super oxidized from the CRT goop. And then after 10s of treatment (taken just now).

yep - definitely have to wash tarn-x off, and don't leave anything soaking in there for long. Nokorode looks hardcore, will check it out!!

This time, I decided to try sous-vide method. Liquid Salon 20 in the freezer bag, run at 50C for about six hours. I also added a UV flood light and metal foil wrap just to be sure.

It’s awesome. Dip and agitate for a few seconds and then a thorough rinse with water. Let me know how you get on @jeriellsworth.bsky.social

I removed two of the ICs on the other path, all good there.

The other two ICs on that path were also affected pretty badly, but cleaned up great. I needed to use some odorless mineral spirits to remove the last of the stubborn goop. Tarn-X helped clean up the IC pins once more.

No surprise that the Z80 socket didn’t fair so well, but it cleaned up just fine. The CPU itself took a dip in Tarn-X that cleaned up corrosion on the pins.

The CRT river of doom took two paths through the ICs.
