Thank you, but doesnt Kontakt 60 consist of acid like ingridients that could harm the PCB ? Thats why Id go with a "isopropyl bath". Anyway, interesting read. =)
That's why I wrote to use both: Kontakt60 (first) and Kontakt61 (after that)! ISOPrpyl Alcohol contains some lubricant which works like glue for some dust/moisture and therefore really not recommended! Anyway, as all times: it's up to the user/owner what to do and that's done on his own risk!!
