Bob,

"My understanding is a light spray (enough to kill Nosema spores) will
dissipate from the comb surface very fast."

One of my jobs is food saftey manager for a commercial kitchen.   The FDA
Model Food Code recommends that 1 teaspoon of clorine bleach per gallon of
water, between 173 and 120 degrees F, to sanitize dishes, silverware, and
food prep surfaces.  After air drying the santized object is acceptable for
sevring food or preparing foor.

The ABJ article referenced a 1:10 ratio of bleach to water.  There are 768
teaspoons per gallon.  This means that the 1:10 mixture is about 78 times
stronger than the amount used in restaurants to sanitize your plate and
fork.  The US EPA recommends letting water stand for 30 minutes after the
addition of 1/8 teaspoon of bleach for disinfecting possibly contaminated
drinking water.  

I think it's safe to say that a 2 day wait period should be adequate for
bleached comb.

WARNING:  The addition of an acid to bleach causes chlorine gas to be
rapidly generated.  Randy has already tested this and found it to be true.
