Craig makes a few different brushes and swabs that are prefect for this task. Also I can’t find the exact name right now but Music Direct sells a little plastic tool that has a male and female RCA molded on each end to scrub both jack. But be careful I have had them break the male part off, so if you get them don’t use the same one too many times. They are cheap enough to toss after about a dozen connectors.
KONTAK CLEANER
My bottle of Kontak cleaner just came today. I have read alot of good reviews about it but none say how to use or apply it. Can anyone that uses it can tell me how to apply it ?
