Ha! Came in here to post a recommendation for Kontak, but ya beat me to it.
Sorry - glad to hear a recommendation for Kontak - Robert / Cable Co recommended it a one of the best cleaners -Being in Australia and postage taking over three weeks (still waiting) - i tend to trust him on most things. Long weekend in Australia hifi all coming out of the racks for cleaningā¦
I will have to try this out. I picked up some XLRs on a great deal. They needed a little TLC, so I used jewelry polish. Iām not sure if its a long term solution, but they looked nice when I finished with them.
Kontak for me too. I use a pipe cleaner for IECās. Be careful to use the Soft version of pipe cleaners. The hard variety is too course.
I use Caigās vacuum tube kit:
