| I have been a repair technician full time for a few years and part time for the last 20 or so. I have a dip tank in the garage, and that is what I'd do. Since you don't, you probably should take it to a shop that can dip it. Having said that, I've been wondering what a product like CLR or some other calcium eating cleaner would do. I suspect that it would strip a lot of the gunk out, but I'd hesitate to try it on a horn that I didn't want to risk damaging.
