Kasra said:i personally really would have appreciated if someone jumped on things like this more often, before i potentially damaged my potentiometers. we need to make a sticky out of this, this isn't a misconception that should be let go any longer than it has to. clearly everyone is not on the same page, and it can cause problems.
Half right, half wrong. The majority of vintage pots are certainly carbon. But some of the higher-end pots like the Alps and Nobles used a conductive plastic film, rather than a carbon element.Lefty said:I would think the vast majority of pots are carbon track. The only other kind are wirewound pots they tend to be lower ohmage and higher power rated, the kind you see in some speakers.

Same stuff, new name.pustelniakr said:I have never seen the Faderlube. Maybe it is new, but, when I know the control is a carbon-based or conductive plastic control, I use Caig's Cailube.
These two (teflon and silicone) are insulators. Use them only if you want your pots to permanantly NOT work.Bogframe said:OK, what about something like Tri-flow, which is teflon based-is that good for pots, would something silicone based be better, or the faderlube?
LBPete said:I contacted Caig tech support to get the word directly from them. Here's the question:
Subject: Dexoit safe for carbon pots?
I restore old audio gear and have been using 5% deoxit spray to clean
potentiometers. I'm now hearing from other techs that it can damage the
carbon traces in some pots. Is this true? Should I stop using it on pots?
Here is the response:
That all depends on the type of DeoxITR 5% spray you are using. The DeoxITR
DN5S-6N spray would be fine, however, the DeoxITR 100% spray (D100S) would
be the preferred choice. Please refer to the link below for more information
on vintage equipment.

Here's my take on their response. The carbon may be damaged by the solvent in the 5% solution. It is more likely to occur if the carbon is worn to begin with. The 100% spray has much less solvent and is OK for potentiometers.
Both the 5% and 100% provide lubrication.
Faderlube has no cleaning properties. It was formerly known as CaiLube MCL
