What's the best home solution for cleaning off stubborn greenish buildup inside the slides? Soaking in hot water with dish soap doesn't seem to do it.
Something more abrasive but safe to use? The horn is raw brass if it matters. |

Hello all,
It is important to have some kind of maintenance schedule to keep your horn clean. I swab my leadpipe after heavy use. I run warm water through my horns once a month. When the hard scale starts to form, I take the horn in to the shop for a sonic cleaning. With a good home cleaning every 3-4 months, I can usually wait 2-3 years before I have the shop do the cleaning. The greenish buildup maybe caused by old grease though. There was a time where I would clean my horn, and the greenish stuff would appear within a week. I was using a lanolin base, and was told that it was old. Once I tossed the old stuff out and started using fresh stuff, I have not had a problem. If you are using a synthetic and getting a greenish buildup, maybe you are just not cleaning your horn often enough.
By the way, I have had to replace leadpipe/tuning slides on older, pre-owned horns because of rot. If I keep the horns clean, I won't have that expense. _________________ Christian K. Peters

I think there’s a good chance that what you’re seeing is verdigris.
https://en.m.wikipedia.org/wiki/Verdigris
I’ve never had much luck trying to get rid of that with standard dish soap cleaning, brushes, etc. Last horn I had that had that (when I bought the older horn), I sent it to Doctor Valve for cleaning.

You don't really have access at home to the things that really dislodge and clean that stuff out, unfortunately. If soaking and a snake hasn't done it, then it needs a flush at a shop.
Regular hope cleaning, swabbing, etc can do a pretty good just if done regularly. However, just like your toothbrush and floss are no substitute for a dental cleaning, there's only so much your snake and water/soap can accomplish. _________________ LA Benge 3X Bb Trumpet

I still chuckle when I recall that I never knew that word until it appeared in a song called "The Wizard and I" in the musical Wicked. _________________ "I'm an engineer, which means I think I know a whole bunch of stuff I really don't."

All the lyrics in that show are noteworthy.
"And one day, he'll say to me, "Elphaba
A girl who is so superior
Shouldn't a girl who's so good inside
Have a matching exterior?
And since folks here to an absurd degree
Seem fixated on your verdigris
Would it be all right by you
If I de-greenify you...""
I saw the show in LA twice during it's initial run. Once with Wayne Bergeron and once with Rick Baptist.
To the OP, good luck de-greenifying your horn. _________________ "I'm an engineer, which means I think I know a whole bunch of stuff I really don't."

Just use Noxon 7 (or Brasso) with a tube brush on the inner tubes to get the corrosion out. And/or soften a chunk of Lava bar soap, get it all over the brush head and in there to scour it out.
Be sure to get all of it out of the horn and do a final cleaning with regular dish soap. Important to get all of the pumice out.

Can try some weak acids like vinegar or citric acid or an acid mixture like CLR, fill up the tubes, let sit for a few minutes and then agitate with a brush to knock it loose. Wash out with soap afterwards. There is a concern of dezinc using acids but that is not an immediate effect and the verdigris will dissolve way faster since that is just a surface corrosion. |

Correct .. I use a weak solution of muriatic (hydrochloric) acid in the shop. Rinse well after and if you want to be thorough about it rinse, in a bicarbonate of soda solution to neutralize the acid. |
