To clean contacts in audio equipment, I do the following:
- clean the contact with Kontakt 60
this will dissolve the corrosion and is slightly acidic. Follow up with 2 & 3. - clean the contact with Kontakt WL or IPA
this will rinse the contact clean and evaporate completely - protect the contact with Kontakt 61
this will put a protective layer on the contacts to prevent corrosion and wear so that you won’t have to do this again next year 🙂
For potentiometers don’t use 60, this will erode the internals. Use Kontakt 390 or Kontakt Tuner(600). Tuner works very well.
Kontakt 390 is an old Philips recipe and should be an all-in-one solution. I have not used it yet.
Don’t use contactspray!
Good luck!
