How do I clean my grooved discs?
For cleaning grooved and optical discs (i.e., acetate, lacquer, shellac, and vinyl records; CDs; DVDs), use canned air to blow away dust. See Cleaning Lacquer Discs (Northeast Document Conservation Center) if it is necessary to clean mold or waxy exudates on grooved discs.
