Handling and Cleaning
Handling An Edison Diamond Disc
As with any other grooved disc, handle Edison Diamond Discs by their edge and label areas only. Do not touch the playing surfaces. Clean hands before handling.

An Important Note on Cleaning Dusty Diamond Discs
Diamond Discs should never be cleaned with water. Clean Diamond Discs only with a soft cloth, cotton ball or tissue dampened with alcohol. Wipe the record in a circular motion, starting from the center and working your way out. Do not re-use dirty cloths/cotton balls/tissues. Do not air-dry; use a fresh cloth to wipe away moisture. Alternatively check the restoration section for cleaning products to use on your Edison Diamond Discs.
