Has anyone else seen a fungus on their slides?

I have 6-7 rolls of slide film (Kodak, Kodachrome 64) that I shot back 
in 1984. They slides were stored in the carousel's I use with the 
projector. (My bad.) Recently I dug up the slides and decided to scan 
them into my computer for archive and enhancement. Much to my surprise, 
what looked fine when projected on a wall or screen, actually had a fine 
  blue & green grit covering the entire slide which was picked up by my 
scanner. (HP_Scanjet 5370C with transparency adapter.) I called Kodak 
customer support and they have told me that Kodachrome from that period 
in time was highly susceptible to growing a fungus, which is what I am 
seeing in my scanned images. The suggestion was to use a strong 
Isopropyl solution and a cotton ball to clean. Haven't found anything 
stronger than rubbing alcohol which is about a 4% solution. I've tried 
using PEC-12, a film cleaning solution and haven't seen much of an 
improvement.

Besides recreating the trip, any other suggestions on dealing with this 
problem?
