 I needed a dial indicator where it got splashed with coolant for a few days.

Now its all sticky and the needle won't return. Can you take one of these
apart for cleaning, or do you get a pile o' parts? What would you spritz on
the inners to remove coolant residue?

When I worked in the shop we would blast 'em with WD40. If that did not do
it either toss 'em or if worth keeping, send 'em somewhere for rebuild. You
should be able to unscrew the back to see the innards, depending on the
type.
If water based coolant even a dip in warm water, followed by some WD40
probably would not hurt it any more than what damage is done already.

Basically what you'll find inside is a very fine-thread rack and pinion. You
might be successful in
cleaning the pair with something or other, but all traces of residue should be
removed before
closing it up again. Now is you had some very good quality instrument oil,
(Starret ?) you might
try it. Otherwise, leave it clean and dry.

For cleaning stuff and leaving NO residue try alcohol, preferably 90%,
followed by acetone followed by Xylene which takes out all acetone and
leaves no residue. Followed by proper lube of course. ;)

Some of the dails have white paint that dissolves in alcohol and
acetone.
Test in a corner before you dunk it. Regards, Charlie
