The Deoxit I bought a few days ago must not contain any of the oleic
acid. Not mentioned on the can. This is Deoxit D5. The can says it
protects surfaces so doubt this is a copper eating compound.


When I was working overseas in a country where all products were required to have all contents listed in clear terms, Cramolin Red had a paper label on it that stated: Ingredients: Oleic Acid 5% Petroleum hydrocarbons and propellants 95%.

The red was a CLEANER, was labeled as a rinse-off-after product. The contact enhancer
was the blue, apply-and-forget. The enhancer works well, but the patent has expired, so Caig literature is rather obscure on the ingredient labels. DeOxit Shield S has NATO stock number
NSN 6850-00-450-5821, and hasn't changed since that number was issued... 47 years ago?
