besides deoxit, does anyone make a good quality contact cleaner ?

Who'da thunk the world would be clamoring for NOS Deoxit cans?

AFAIK the cans with the older nozzles are still available. The new one is an OPTION, not a replacement. But they both suck. Just pisses me off you pay a insane amount for the stuff and they use inferior delivery systems. Thier CEO must have a few extra jags in his garage at our expense.

Deoxit is horrendously expensive in the UK. I use this - Servisol

What worries me with Servisol is that the spec says conductive. Might be a problem in high impedance circuits. All deoxidizing contact cleaners if have tested (Deoxit, Cramolin Contaclean, Kontakt 60) are non-conductive, resp. show a resistance >100MOhms.
And if a cleaner is of the lubricating type, it must leave an oily/greasy residue, which is not always desirable.
