The above is so important! Every deadout which returns to my shop gets a
treatment to kill nosema spores.

The method we use is to clean frame rails. burr comb and remove inferior
comb. Then we spray a light spray of Clorox solution.

acetic acid would be the second choice but takes longer and costs are
higher.

we have reused frames treated with  a light Clorox solution spray after a
couple days with no problems.

When I have told other beeks about the method a few have said they have been
using a light Clorox solution for decades on deadouts!
