I have a 8 inch Digimatic caliper that is extremely dirty. I want to
clean it, but at the same time I do not want to ruin it (like I would

from grime etc.

thanks

I have used contact cleaner (the kind safe for plastic). Works fine
with no problems as yet after several uses.
Also works great for cleaning gummed up indicators.
