I have had ultrasonics blow holes through spots of a horn that had some red-rot. You know, the pink spots where the zinc has rotted out of the brass alloy. I can't think of any reason to use acid on the bell of a horn. Simple Green is good for cutting grease, I use it for cleaning some of the old greasy crusty machines that I've bought at auctions. The dang stuff stinks like H.E. double hockey sticks though!!! Probably a lot more grease cutting firepower than you need for cleaning a horn, it will cut the grease, not the corrosion. Get the same results with much better smell using dish soap. I imagine if Kaboom brightens the brass, it probably contains some kind of acid, maybe citric acid? Check out the ingredients label. If it does, it's probably a good idea to follow up by neutralizing the acid, otherwise it tends to promote corrosion. A solution of water and baking soda, or Windex will work. Really, for the most part all you need is soap and water. Just do it often enough.
