Re: [ARSCLIST] RV: [ARSCLIST] Cleaning of grooved discs- how about fungus?

Sounds like you have a PH problem. My experience as an historical archivist would suggest using a neutral/acid free paper between your cds and an acid-free storage box. Acidic PH is the opposite of your problem (too basic) but you don't want to switch fungus for a corrosive. Keep it neutral.

Thanks. I was being slightly fascetious about CDs, and by glass and crdboard, I meant the substrate of 78s... I did not realize you didn't know! Interesting challenge. I only do tape so sorry I can't help either. Good luck!
