The rubber cement process does work. I have seen it demonstrated several
times, by its discoverer, Ed Wilkinson.

One day decades ago, he wanted to re-glue a label that had fallen off a
lacquer with severe palmitic acid problems. He had rubber cement handy, so
he used it. Some of the glue got on the disc beyond the label. After the
glue dried, he peeled it off the non-label area and then noticed that the
palmitic acid residue was gone. He tried it over the rest of the disc and
found that it removed the acid completely. When played, the disc was quiet.
Voila!

Several years ago, I was working on a lacquer project with Ed, and he
applied his process to some discs. I asked him how this worked. He opined
that the glue attached itself to the residue and it peeled off with the
dried glue.

On a hunch, I looked up the MSDS for rubber cement. Various solvents are
used in the making of rubber cement, it varies by manufacturer. I suggested
that we buy a can of one of them.

The solvent was applied to a test disc and then washed off. Result: no
palmitic acid. And no drying and peeling required.

I don't know the long term effect on the lacquer of using such solvents.

Years ago...before we knew better...many of us used to clean lacquer discs
by applying a coating of rubber cement to the disc and then peeling it
off...carefully.
