There is a tool called a file card that will remove wax from a
file by running it across the file, much faster...
Yes, file cards I know about, but I don’t use them because the wires
don’t get down in the file’s grooves very well. I use a small pencil
type wire brush designed for cleaning burs. The filaments are much
finer. But aside from that, that wasn’t my point. You’d have to try
my technique to see what I discovered with it. It sort of dissolves
as it cuts, leaving a smooth surface, and it’s quick, compared to
stopping every few seconds to clean the file.
Also, what works better than a file card on larger files is simply a
strip of brass, around 16 guage, 1 inch by 4 inches. Run the end of
it across the file, pushing it down into the grooves. It contours
itself to the file’s ridges and grooves, and although it’s a bit more
work than a file card, it doesn’t trash the file the way the file
card does (file cards dull files because the wires are pretty close
in hardness and don’t fit down in the grooves).
