I remember a few heated discussions about this years back, with many professional beeks saying that it was unnecessary, especially since honey is such an inhospitable environment for bacteria. And for professionals who probably go through jars quickly, that makes sense. But for me, who stores them in my basement until I need them (which can be many months), I think a sanitary wash is appropriate. Also, given the current pandemic, it's probably best to be a little overcautious - so wash your jars, tools and implements, and your hands.
