First posting here, so maybe this has come up before.  From:
 
Goodwin, R.M., Haine, H.M. 1998: Using paraffin wax and steam chests to
sterilise hive parts that have been in contact with colonies with American
foulbrood disease. New Zealand Beekeeper 5(4): 21.

"New Zealand apiarists have used hot wax dipping to sterilise hive
parts contaminated with American foulbrood spores (Paenibacillus
larvae) for over 30 years. Experience showed that the process was
effective. However, it was not until 1998 that Goodwin and Haine
conducted research and proved that hot wax dipping, when used
correctly, would render all AFB spores non-viable."

Question: Does anyone do this for contaminated equipment?
