Solvent to clean hardened grease on an old Nak?

[gonzo]

I have a 682 ZX that has hardened grease on some of the mechanical parts. What is a good and safe solvent to use that won't damage any of the plastic cog wheels, etc. Thanks Norm

I had the same issue on a Nak 480. I ended up removing the parts (a capstan swing-arm assy) and using a toothpick to scrap away the hardened grease, then some light teflon lube to soak in until the parts "broke free" of the crust inside. Then I had to use some crocus cloth (~ 1600-grit sand/polishing paper) to home down the capstan swingarm shaft and polish it up. After that, I went out and got some nylon dental pics to use for longer reach so I didn't have to disassemble stuff to do this.

If it's truly stuck and stuck-bad, place the tip of a hot soldering iron against any metal parts (like shafts) and that will soften the grease a tad. Don't leave it there too long ...

when i got my PIONEER CT-W910R, it had these random dry spatters of some sort of transparent, lauquer like substance around the front panel. the largest of which can clearly be seen here, between the REC LEVEL and BALANCE knobs:

i have since been able to remove most of those spatters, including those between the knobs, but there is a tiny one i have been working on here, seen on the base of the "T" of the "AUTO" legend:

i have not been getting anywhere on it, as i've been afraid to scratch too hard at it for fear of damaging the letter underneath...

sorry, i just figured that the author's "hardened grease" and the hardened substance on my deck might be a similar enough problem that me and the thread author might just be able to throw some ideas around on how to safely remove them both. i just felt it necessary to show my problem visually so he might get the clearest idea on what my problem is and how similar it seems to be to his own. i might have expounded upon this better in my offending post above, but believe that i might have been in a hurry at that time, and i wanted to get my post up ASAP so the author might notice it. again, sorry...
