Oxalic Acid Residue

[Erichalfbee]

Has anybody a link to the research pointing to no oxalic residue remaining in the hive after sublimation.
I've read it often enough but when I need it? Sheesh!!!!!
Thanks

I've only found the Dadant pdf which states the bees remove the residue within days and also the use of a vaporiser only produces formic acid and carbon monoxide in the laboratory not the apiary. https://www.google.com/url?sa=t&sou...Vaw1nL0aGf2ZZ-9Bf567TVJVn&cshid=1572857838649
