Good afternoon I hope everyone is safe and well 
please can someone give me some advice on which contact cleaner is best to use ? I just got a 52 supercap and 250 olive and whoever had it beforeme really didn’t look after it, its filthy, I have cleaned the outer casings with an antistac ckeaner from rs products but what do I use for the input sockets, they have oxidation and are really dirty and need to be cleaned badly, ive tried speaking to a few electrical shops but they were as much use as a handbrake on a canoe, I have heard of deoxit d5 and Wd40 specialist contact cleaner but the Internet being what it is, is just confusing with different opinions about different products so I thought Id ask if anyone has any experience with the problem I have, anyway please stay safe everyone and look after yourselves
I’ve never opened up a Naim box before, but I have used Servisol Super 10 successfully on various pots. For cleaning terminals however I would typically use IPA
Thank you, the bxes are the shipping boxes, its for the din connection , sorry my mistake
Maybe move to the HiFi room…
In that case, IPA
Yes. Post in the correct forum if you want replies! I’ll ask @Richard.Dane to move it.
DIN plugs are self cleaning by design. Pull the plug out of the socket and push it back in a couple of times and that should be all that’s required to clean the actual contact areas, which is what really matters.
Any further cleaning of DINs is more cosmetic.
Other contacts (RCA, XLR, 4mm bananas) are not self cleaning in the same way, so some manual cleaning here may well help. Most important is often the insides of the banana sockets on the power amp (and possibly your speakers too) so sticking a cotton bud with a bit of IPA in them may well help there.
Left is new one. Right is after cleaning one banana socket on my NAP500.
Interrupted this afternoon’s listening to power down the system and clean the banana contacts of both NAP 300DR and speakers with q-tip and a bit of isopropyl alcohol solution. I was a bit surprised with how much black gunge was extracted. Audibly, a bit of a veil of clarity seems to have been lifted so well worth it.
