Good item to put on the list?

    In the most recent Radio Shack catalog is listed a product that cleans
    the optical lens in the compact disc player.  It is a disc in itself.
    It is stock # 42-123 and lists for $14.95.  Radio Shack also has a
    battery powered CD cleaner that cleans the disc.  The stock # is 42-124
    and it sells for $29.95.

    There are of course other companies with equal or better products on the
    market.  My question is:  Have these products been tested to be reliable
    for use with a large collection of discs and shown to be harmless to
    them over time?  Has anyone been applying a particular cleaner to their
    discs? Preservationists, please jump in!
