While I was advised once to avoid most contact cleaning sprays
like the plague with regards to pots as they tend to be corrosive
or otherwise harmful to pots in the long term, one guy told me of
his success with a spray called:<br>
<br>
"Tuner 600" by manufacturer Kontakt Chemie, looks german but I saw
it @ farnell uk:<br>
<br>

I used that maybe 5 years ago, on a stereo volume pot (which gets
lots of movement) of my early 1990's Technics hifi audio amp. The
pot had some smalls holes somewhere on the sides, i just sprayed
it in everywhere, generously.<br>
So far, that pot has not had any scratching noise issues, let
alone dead spots, anymore whatsoever.<br>

You definitely don't want a lubricant that does turn into a resin
over time, like some mineral oils do, because that eventually
bakes the dust onto the track. I recon that is where the "no lube
on tracks" comes from.
<br>
<br>
I've read people claim the crackling doesn't (only) come from
dust/dirt, but from oxidation on the metal contact tips. There a
lubricant would actually help to keep air out of the contact by
creating a seal. (Some metal/metal contacts seem to be coated with
grease for this purpose.) Somewhat supporting this idea is, that
there are some pots that have wipers with a little carbon piece in
it, the few ones I had in my hands weren't noisy even after years
of storage. They must have been dusty as well, but if they were
oxidized, the CO2 was long gone. :)
<br>
<br>
The truth is probably somewhere between this, some pots are mainly
dusty, and some are oxidized... Requiring different treatment
maybe?!
<br>
<br>
Sprays (containing typical fast evaporating hydrocarbons) might
remove or the displace the intended greasing of the bushings. The
result being a less smooth feel.
<br>
<br>
FWIW, the European counterparts to Caig Products seem to be
<br>
Tuner 600 / and WL from Kontakt Chemie.

I believe D5 is for switches and F5 is for pots.

What you’re looking for is Deoxit D5. You just spray it
inside
<br>
the pot and turn it a few times. Works great.

Hi,
<br>
<br>
I'm about to clean a scratchy volume pot of my Korg
Polysix. I
<br>
was thinking of dismantling the pot and using
isoprophyl
<br>
alcohol to clean the wiper contacts. However, am I
also
<br>
supposed to add some very small amount of lubricant
(such as
<br>
PRF Kontakt 7-78) to the contacts after cleaning or
would it
<br>
be better to leave it dry?
<br>
<br>
Also, in general do new factory fresh pots have
lubricant on
<br>
the contacts or are they dry?
<br>
<br>
I'm asking these questions because no amount of
googling seems
<br>
to give a definite answer, but if there is an answer
<br>
somewhere, it's in this group 🙂
<br>
<br>
Thanks in advance,
<br>
Antti
