“The point of the dubbing needle can quickly become covered with a build-up of varnish, epoxy and head cement.  This can be scraped away with a blade, but I keep my needles clean with another method. I have a 35 mm film canister that I have filled with wire wool. All you need to do is push your built-up dubbing needle through the canister top down into the wire wool a few times and your needle is as new!” (Mustad Fly Tying Helpful Hints)
