It's time to duplicate these and try whatever cleaning method you find on the web but these are gone.
The southeast is known for high humidity and mold. My DVDs are in a carousel and some have spots of mold on them, consequently, they won't play. I gently wiped them off with a dry towel and I tried to rub off the mold, to no avail. Is there a way to remove specks of mold from DVDs so that they will be playable?
