Then N2 Blow dry. However sometimes there is some traces of some polymer residue, presumably either polyimide or PMMA that has dried and cross linked. Can you recommend an alternative cleaning that could be performed?

The fuse blew as I was trying to ramp up the speed. I borrowed the same amperage resistor from the dump rinser at wbmiscres to see if it was a fluke. Nope - that one blew too. So now there are two blown fuses - one for headway2, and one for the dump rinser at wbmiscres.
