I've done moldy tapes, varying degrees of mold. A Pelon wipe has solved the problem for me. But, let 
me say these are not the fuzzy-bushy molded kind of tapes I've seen ruined in a damp storage room. 
Those tapes were original cellulose-backed Scotch 111 and the mold actually ate the tape away 
(actually probably ate the cellulose, leaving a pile of wet rust behind). This would have been over 
20+ years in a trunk in a damp but never flooded storage room. It's too bad, too, because the tapes 
were field recordings made in rural Korea during the Korean war era. In contast, early and mid 50's 
Audiotape that had grown a slight beard of mold were cleanable and playable, stored in the same room 
but not the same trunk. Later plastic-backed tapes don't even seem to grow mold -- the mold eats the 
box but not the tape or the reels.

One man's experience, etc.
