I agree with Dave Weiner to a point. The scary thing is that there are way
too many shops in this country (not Dave's!) who will destroy your horn in the
process of getting that green crud out of there. I personally have known
people who would put a horn in Brite Dip (powerful acid) and then go to lunch.
Cleaning that green stuff out takes time/patience and/or expensive equipment.
I just got an eBay horn that the repairman-seller was very proud of.
Everything, slides,valves etc. is loose and leaky from the Brite Dip. It
doesn't play at all.
So my point is, buyer beware! Find a repair tech who truly understands
that french horns aren't supposed to leak, and who's willing to take the time
to do it right. I'd stick with the green if the other choice was getting my
horn boiled into nothingness in acid. Acids can be used, but shouldn't be
overused.
- Steve Mumford
Just for reference:
Chemical clean = acid (usually)
toilet bowl cleaner = acid
Lime-a-Way = acid
Vinegar = acid
acids need to be neutralized if used on a horn, or the green just comes back
better than ever.
