    I like this for cleaning alum not to harsh. I mixed up some in a gal bucket and dropped a spool of alum mig wire that was real old in it for a couple of minutes rinsed it of blew it out and let it dry welded like it was brand new I don't know why it wouldn't clean your filler rod a gal will last you a long time and it beats wire brushing or sanding. I buy it at a local cleaning supply.

    I bumped up to a 3/4 " cup and I think it solved all of my Woes.
    Acording to the miller Tig Calculator I should use 1/2 to 3/4 cup on 1/4" butt welds.

    I had 5/8 cup but couldnt run a bead larger than a pea with out contamination.

    When in doubt go up a cup size.
