Odd question here, but it does pertain to breaking in a new mill, or as in my case, just beginning to use a mill at home. After milling my grist, their is grain dust all over the mill and base. Should I be trying to brush that in with the rest of the milled grain? Is is just dust and not necessary? I really had not thought of it when using the mill at LHBS, as I was not trying to clean or store that mill. I now see a lot of build up static clinging to my mill and the base of my mill. Do I need to get as much of this in as possible to protect my efficiency or is it essentially unwanted debris?
