I am going to rub some alcohol (isopropyl) and let it dry during the day.

Hi, Eddie,

I wish I had a 41C/CV/CX... but it is on my wish list, of course.

As stated above by ElectroDuende, the safest method to a more effective cleaning would be to disassemble the machine.
This is a general rule that I follow for any equipment. The accidental damages will be minimized in this way.

The cleaning procedures you are doing are good enough to remove recent leaking on the outside, but what about the inside? Leaking goes everywhere usually.

For corroded metal I would go for more aggressive measures, and that can only be done by taking the machine apart to work in a safe way.
