The question sometimes arises as to the proper surface cleaning method for Edison Diamond Discs. Rule #1: Never use water. (If water gets into the core of the record, it will be destroyed.) We use medical grade 91% isopropyl alcohol which can be purchased at most pharmacies.
We apply it to the surface needing to be cleaned with a cotton swab rubbing it onto the record in a circular motion in the same tangent as the record groove. We are careful not to let the alcohol get onto the edge of the record or on the label and/or center hole. Next, we remove the alcohol with a clean cotton swab, again using a circular motion tangential to the groove cut. If there seems to be residue left on the cotton swab used to dry the record, then we repeat the process using the alcohol. We only recommend the use of isopropyl alcohol.

"If records become soiled and need cleaning, wipe with cloth dampened with alcohol. Wipe dry with small piece of silk velvet.
DO NOT USE WATER"
