I have a pretty nice stainless steel caliper that was given to me by a friend. I imagine he used it on hsi reloading bench for at least 30 years and I have had it for 10. Well, over the years it has gotten pretty gummed up with who knows what, probably gun oil or cleaning products mixed with dust. I keep it in a case but my friend apparently didnt. Its still accurate but it doest move smoothly along the teeth. I tried a soft toothbrush but I think it needs some sort of a degreaser or something to flush away the grime. Before I ruin it or destroy its accuracy, I thought I would ask here for suggestions. It has 2 tiny screws on the front next to the dial. Should I try taking it apart? Hose it down with brake cleaner? suggestions? Its not a japanese top of the line tool but it does have sentimental value so I would like to keep it in service versus just ordering a $49.99 repalcement on Amazon.
 
90% Isopropyl soak just the rack.
Blow out with canned air not high pressure.
Unless you want a lot of spare parts do not open the slide :)
Once the rack is clean apply a little more Isopropyl to the rack and move the slide over the wet area.
Blow out again.

I have a Starett dial caliper from the '80s that still works fine.
Even missing the cover glass (plastic)

Perfect. Working smooth again! Thank you.
 
I have an old Starrett that was getting pretty gummed up. I found a video online which showed me how to take it apart and clean. I did this and it has worked great. That Starrett will probably last a few generations.
