Hifi contact cleaner

[peteh]

Hi,

Need to get some sort of hi-fi / electrical contact cleaner?

Any place I could go - any trade names I could ask for.

Basically I have some contact switches that need a bit of lubricating.

Thanks
Peter

Which side of the Arctic Circle are you on? Usually this stuff is sold by electronics/hardware/hobby stores as well as car parts dealers.

In general, you'd use "blue" PRF (6-68) for non-sliding switches, and "brown" PRF (7-78) for pots and slider switches.

I believe "CRC Contact Cleaner" does about the same as PRF 6-68. Some people say LPS-1 is good stuff for pots.

CRC
ethyl alcohol, if you cant get the above..
Easiest contact cleaner is called as "sand paper"..

Well another ( expensive ) solution is to use a Gold as soldering agent.

...but it's definitely not recommended. Sanding removes the plating from on the contacts and guarantees even quicker oxidisation.

Instead, cotton buds are fine, either dry or with ethanol or isopropanol.

yes and no..
I didnt mean using the sand paper to remove the "conducting plates"...instead remove the top layer
and then you can then use a solder to add more plating or use a cleaner OR
keep it like that..and clean it with CRC!!
Anyway the conducting plates will still oxidizes!!
Easiest is to use a vacuum cleaner to clean the dust and a small blower fan to clean more dust..
