Handling and Cleaning

Disc Cleaning

Use a dry soft cloth to wipe the disc surface. For stubborn dirt, use a soft cloth slightly dampened with isopropyl (rubbing) alcohol. Avoid solvents like benzine, thinner, or conventional record cleaners, as they may damage the disc surface.

Note: Minor scratches from handling are normal and do not indicate a player problem.

Preparing New Discs with Rough Spots

New discs may have rough edges. If a disc with rough edges is used, proper settings may not be achieved, and the disc may not play. To remove rough edges, gently press the side of a ballpoint pen or pencil against the inside and outside edges of the disc.
