Thanks for catching me on that. I'm to familiar with my own instructions. It is also good to slop the baking soda rinse all over the outside, especially if you can't resist using the acid cleaner for a little tarnish removal on the outside, or if you've done some soldering with acid flux solder.
I've become partial to the hydrochloric acid toilet bowl cleaner that 'clings to the bowl'. My guess is they thicken it with fumed silica or alumina (Cabosil or Alon-C). Does anyone know for sure or whether the additive might pose a potential problem. I haven't seen any problems so far. I buy mine from an industrial cleaning place, by the case. A quart generously does everything I want to do to a horn, and can obviously be run down any drain with no more environmental consequence than cleaning a toilet. With a few stoppers from the hardware store, I can isolate, and fill, the entire horn in stages. I do it in the kitchen sink with a strainer to hold upright various crooks. I can even use the three timers on the microwave, and upper and lower ovens. Make your claim to full use kitchen time so no one else is inconvenienced. The HCl content varies by product. A web search for the materials safety data sheet, MSDS, will easily locate any product and list the ingredients and concentration David Jewell wrote on 6/9/2004, 10:09 AM: > Hi Steve - in addition the the excellent advice that Mr. Bamberger > gave you and the list - I need to add that any time you use an acid > type of cleaner you need to immediately rinse with a watery solution > of baking soda - you need to stop any acid/metal reaction and plain > water won't do it.
