Great, thanks for the clarification. It seemed like all the instructions on this I've read either use the brass brush or the base cleaner, but not both. . .the step may have just been left out. I did just read about the hot scrape method. I may have to give that a try.
So, I'm kind of assuming no direct response means yes, but just to clarify, a brass brush is indeed a brush with brass bristles, correct?
