(continuing) reply to Knut ...
 
        I have no direct answer to this modification of the known process
cleaning combs and hives contaminated by nosema ... but I have some about
the binary system "acetic acid/water" (60-40).
 
        First, water will evaporate (not pure water, but a mixture of water
(97 %) and acid (3 %)) until all the water is lost.  Then the acid will
evaporate as a pure product.  Thus, it seems to me to use more mixture
(150 ml) for a longer time (2 weeks? in closed room, water will get out
very slowly).
