"For fun"


I have a DMM that is suffering from dim LCD segments.
I beleive that the conductive rubber betwee the PCB and the LCD is causing
the issue.
What are the recommendations of cleaning the contacts on the PCB, LCD &
rubber?


** I have used IPA = Iso Propyl Alcohol with success.

Or else try good old methylated spirits = denatured alcohol.

Wet a cloth and used that to gently wipe the surfaces clean.
