What to use for cleaning switches, pots and rotary encoders?

Can't find it now, but I'm also sure I've read somewhere about an acrimonious sale or parting of ways involving Caig and someone.

Yes, I can buy it here!
I checked its contents which says Naphtha and isopropyl alcohol, so this means no lubrication.
I'm confused, because alm says it's very important with lubrication for switches, but does this only apply if it has gold contacts?

The place I found the PRF 6-68 also sells other Taerosol products, but I don't know what they're suitable for:
PRF IPA Kontakt (isopropyl alcohol, non-lubricative), PRF 7-78 Kontakt (Hydrocarbons C9-16 hydro-treated dearomatized, isopropyl alcohol, lubricative) and PRF TCC contact cleaner (naphtha, non-lubricative).

I haven't had any success in finding Cramolin, KF F2 or Servisol here, and ordering from abroad is either very expensive or not possible (because of shipping restrictions for dangerous goods).

What's "IPA"?
I can't find Cramolin here either unfortunately. Perhaps one of the Taeorosol products I just mentioned work in the same way as Cramolin and Deoxit D5?

IPA = isopropyl alcohol

Sredni:
Perhaps this is the reason Cramolin is hard to find?

Cramolin Replacement Inquiry
http://store.caig.com/s.nl/ctype.KB/it.I/id.1411/KB.215/.f
Years ago I had this spray product for use on the electrical switching devices of a Schober Organ. It contained 47% trichlorotrifluoroethane.
I don't see this listed in your current products. Is it now under a different name? I still have the organ and am in need of a spray product to clean the switching devices. Please advise which of your products you recommend.

Thanks,
P. Stough

Answer
What you're referencing is the old Cramolin R5 with TF solvent, and it's now banned by the EPA. The replacement is the DeoxIT® (D5S-6), with petroleum naphtha as the carrier solvent or the new DeoxIT® DN5 (DN5S-6N), which is non-flammable, non-drip and safe on plastics.
