It sure has solved a lot of problems over the years for me.

According to some of the posters at rec.antiques.radio+phono, DeOxit is
Caig's clone of Cramolin Red, made in Germany. Cramolin has been traced
back to an even older product known as Gramolin.

Cramolin Red is supposed to be a pretty simple product:

"That formula as called out on stick-on labels put on German-made cans is 5%
Oleic Acid, 95% hydrocarbons and propellants."

A regular at the antique radio and phono had been selling oleic acid as a
"DeOxit equivalent" product. Caig sicced their lawyer on him:

He is still selling the same stuff, now as "Cease and Desist Contact
Cleaner".


Here's a look at the Caig - Cramolin controversy including a quoted letter
from Caig:

I've also used some of the less expensive CRC contact cleaners from the
hardware store with good results. CRC Lectra Clean has a powerful flammable
solvent which will nicely remove carbonized grease. Even tiny droplets of
that stuff will ruin paint and a steady spray will bore a hole right through
common plastics such as styrene and ABS. CRC QD contact cleaner is much
gentler. Both evaporate quickly and leave little or no residue. CRC 2-26
leaves a thicker film than DeOxit and I don't trust it to try it in pots,
but it's been good on switches. 2-26 kept a crummy headphone contact in my
Walkman working better than DeOxit.

My last resort cleaner on brass contacts is Tarn-X. I like to work on old
radios, and 50 years of age and bad storage can create a corrosion seemingly
immune to even the best cleaners. I suppose the cleaners are doing their
job, but there's such a bulk of oxidation on the contacts that normal wiping
action is often breaking off a new piece of grunge to foul the contact yet
again. Tarn-X does a good job of stripping off these oxides, but I fear
that stuff will be wicked up into the cloth backing of the Bakelite contact
holders and might cause conduction/corrosion problems later, so I give them
a good water soaking afterwards followed with plenty of alcohol then CRC QD
and DeOxit. I've only had to do this a couple of times and it's worked
well.

I do like the Caig products but when I run out, I think I'll try the Cease
and Desist stuff.
