  Can you please tell us, does cleaning with 100% ethanol really 
qualify as "disinfecting"?  If you have different procedures or 
suggestions, we'd appreciate those as well.

As I recall, 70% ethanol is more effective as a disinfectant than 
100% for physicochemical reasons I don't recall.

ETOH is not very effective for killing TB or prion disease organisms. 
Bleach will.

The British have a lot more experience with prion disease (Mad Cow, 
Scrapi, CJD etc). What do you Brits use for disinfecting.

What is the problem with bleach and the microtome parts?
