My brother is a devoted audio enthusiast, who avidly reads an 'exclusive'

read that the sound quality of audio played back from CD's that had been
"cleaned" with Armor-all is dramatically improved as compared to untreated
CD's. On a visit to his home, he delighted in playing two copies of the
same CD, one treated with Armor-all, the other one pristine, out-of-the-box
condition. I didn't have the heart to tell him I could hear no difference

Plastics and chemistry is an arcane, dark art. I have an overly pessimistic
attitude about the wisdom of combining such stuff unless there is abundant

Best wishes....

Armor-all is a popular product for cleaning interiors of automobiles. It is
