Elusive stuff, that cleaner

Anybody wonder how the Library of Congress cleans its vinyl records, CDs, and DVDs? Like this:

Cleaning Solution for Audio Records, CDs, and DVDs

The following cleaning solution is used by the Library of Congress for cleaning acetate, lacquer, shellac, and vinyl records as well as CDs and DVDs. It has not been compared for its effectiveness against commercial products.

Preparation and Directions for Use

  1. To prepare 4 L (~ 1 gal) of solution, place 2 mL of Tergitol™ 15-S-7 Surfactant into a suitable container (glass, stainless steel type 304 or 316, fiberglass-reinforced polyester, polyethylene, or polypropylene) and fill with deionized water. This results in a 0.05% solution.
  2. Store the solution in a non-food refrigerator to avoid degradation and transfer what is immediately needed to a spray bottle for manual cleaning or other container for mechanized cleaning.
  3. Store the pure Tergitol™ in its original container (preferably under nitrogen) and in a non-food refrigerator to avoid degradation that causes an undesirable color and odor.
  4. To manually clean records, CDs, or DVDs manually, spray the solution onto the surface, and wipe with an eyeglass or other similar soft wipe to remove contaminants. ALWAYS FOLLOW CLEANING WITH A THOROUGH RINSING WITH DEIONIZED WATER TO REMOVE ALL TRACES OF DETERGENT: LEAVING DETERGENT ON THE OBJECT MIGHT FACILITATE DEGRADATION OF THE OBJECT. Finally, wipe the object dry using a soft, nonabrasive, lint-free cloth.

Trouble is, Tergitol seems to be available only through chemical supply companies.

can't you just picture some kid with a Ph.D in something cleaning records all day long?

These people have it and appear to be at least somewhat consumer oriented. Can't help you with the nitrogen cylinder for storing the excess material under N2, though. :)

Oh, for the days when every toy store had a display rack of Perfect brand lab chemicals and supplies.
