How do I clean my minor burner? I clean the nozzles out pretty much each torch session with the tip cleaner set I purchased from my welding supply store, but I've noticed little nodules of carbon buildup on the face while working.

I understand it's a good idea to brush the torch face off with a wire brush as well, but that using the wrong type of wire brush can potentially damage the torch face, creating scratches where additional carbon can build up, what kind of brush should I use? Brass?

Any other tips on the care and feeding of a Minor Burner?

Thanks in advance for any and all answers!

PS: The reason for this is that I noticed that that the flame was a little unsteady last night, and when I bumped the torch I saw some "sparklies" in the flame.
