That is correct, in the early 1990s.

Supposedly, the actual results of the treatment was damaging.

When there was damage, it appeared to emante from the scratches
accidentally introduced by too rough a treatment. These scratches
can be polished out.

In 1991 I treated one of identiucal pairs of CDs with ArmorAll.
Every couple of years I get the treated discs out to see if they
still play. They do.

I am also investigating the incidence of c!/C2 errors compared
with the untreated CDs for an article to appear in a future issue
of Stereophile.

How could anyone with an IQ above 85 be suckered into
coating their CD recordings with Armor All? At best it would
do nothing bad or good (although fooling with it would eat
up a lot of time doing the applying) and at worst it could
damage the discs.

Apparently, in some cases it did just that. I believe that
Tellig did a follow-up column later on that explained how to
remove Armor All.

What a joke.
