I use walnut hulls myself for rather cleaner brass and corn cob for the really dirty then finish up with walnut hull. I get my walnut hull stuff at the pet store and it is for lizard cages. Cheaper than the Lyman stuff and I add just some car polish my brother gave me, no ammonia, like others have said. Bad juju for the brass.
I also don't like the rice. Didn't work as good as the others. And then I tried to re-use instead of just throwing it out. Even with hot sauce, it didn't make the pollo loco taste worth a darn!!!!!!
