Jewelry cleaning solution with Oleic Acid


#1

I have “The Jewelry Repair Manual” by R. Allen Hardy @ 1956.

He has a jewelry cleaning solution that contains 1 oz. acetone, 1
oz. oleic acid, 14 ozs. aqua-ammonia, 16 ozs. water. This will equal
a 1 quart of mixture of cleaning solution.

What is the oleic acid? Is it used any more as part of a jewelry
cleaner?

I know that some of the things in his book seem to be outdated as he
also mentions a tarnish remover with one of the ingredients as
cyanide, (the poison).

Just a note. Acetone is really a dangerous solvent. I don’t know
what oleic acid is but I would not use acetone in my studio. It is
volatile in that it evaporates into the air and you end up breathing
the stuff. I know someone who had to have a liver transplant due to
improper use of solvents. He washed his paint brushes out with the
stuff and would get it all over his hands. After about 5 years as a
painter he had to get a new liver. Yes, your use might be safer and
less frequent but it is tricky stuff and people take it for granted.
Just because you can buy it over the counter doesn’t make it safe.

Good luck. Dennis

Hi, Larry - I don’t want anyone to think that I just know this stuff

  • I went and looked it up. Oleic acid is an omega-9 fatty acid. It
    is the main component of olive oil. I think this comes under the
    heading of, “What’s wrong with soap?”
