Is it OK to clean AC cable blades and ground pins with ProGold (DeToxIt)? If not, what's your cleaning substance (or method) of choice?
isophophyl alchohol is the only chemical i would recommend.using anything else would not be smart.
I use a Squalan Oil TR-30 by Yamamurra ( I think). I'm not sure you can get it any more but there are multiple contact solutions available from places like Music Direct ( where you can get Walker Audio) & Acoustic Sounds. Dont neglect the ac outlet as well.
