Fixing Worn or Cracking Potentiometers, Switches and Connectors
- Remove all corrosion with Kontakt 60
- Clean the contacts with Kontakt WL
- Put an anti-oxydation film on the contacts with Kontakt 61
From the Kontakt-website:
"The cleaning and oxide-dissolving action can be improved by mechanical support. If switching or connector contacts are readily accessible, they can be carefully wiped, for example, using cellulose, leather or cotton swabs.
If it is impossible to provide mechanical support, allow Kontakt 60 some 10 to 15 minutes to penetrate.
Optimum results are obtained, if dissolved dirt and corrosion products are then rinsed off with Kontakt WL.
After that, Kontakt 61 is applied as a protective film. Kontakt 60 works in many cases even without after-treatment. However this increases the risk that corrosion damage will appear again after a short time."
