Returning to my shop after working
outside this summer, I noticed a rusty
film on my router collets and bits.What’s
the best way to remove the rust without
damaging the collets and bits?
Use a synthetic steel wool or 3M
Scotch-Brite pad. To clean a 1/2-in. collet,
wrap the pad around a 1/4-in. dowel and
spin it inside the collet. Clean the rust off
the bit shanks by rubbing the pads around
them. Do not use an emery cloth or sandpaper;
you don’t want to remove any metal
that could cause the bit to wobble later.
Wipe the collet’s inside and the bit’s shank
with a light, general-purpose grease, then
wipe off the excess.A thin film of grease will
remain in the surface to slow future rusting.
