Kinda big search area. A little more location detail will help with suggestions.

I suggest an ultrasonic cleaning rather than a chemical clean. The ultrasonic clean is more effective and does not damage the instrument in any way. You will have to find a full-service repair shop that owns an ultrasonic machine.

This is true only if there is no "red rot" (de-zincification) in the brass which is the result of not keeping up maintenance. You see, the leaching out of zinc from the alloy made up of 70% copper and 30% zinc is the result of storing your instrument wet over a long period of time. Once 30% of the material has been etched away it is easy to blow holes through the bulls eye center of red spots, most commonly found in your leadpipe and tuning slide closest to the source of moisture from your breath.

In our shop we employ both methods, choosing the one that is most appropriate to archive the desired result.

Also worth mentioning, breaks in lacquer and bubbles in plated finishes will also be aggravated by ultrasonic baths that require heating to maximize effectiveness.

Your best bet is to choose a shop with the EXPERIENCE to do a proper cleaning (see years of service in my signature).

My two cents.

This; Doctor Valve recommended something similar for my ‘56 Olds Recording, even though it’s in excellent condition.

Not to make a blanket indictment of local repair people, but I always send my horns to Steve, because his work is excellent and I simply don’t know that there is anyone local with proper expertise.

Brad361, we hear similar stories from mail in customers that their local school shop is not up to the task. Admittedly, I received my initial training in a school shop performing play conditions, and then an internship at an overhaul facility. Not to disparage the work these fine crafts men and women do, they have their work cut out for them. They're oftentimes faced with instruments that have seen hard use on the football field and programs with limited resources. Been there, done that. Thirty years ago this year I made the conscious decision to seek employment in a pro brass shop where I could hone my skills to a higher degree. Thanks to Steve Shires I was given the opportunity to come work for Osmun Brass in Massachusetts. Here I've had the honor of servicing instruments for members of the BSO, Empire Brass, Boston Brass, the faculty and students of NEC, Berklee, Boston Conservatory, and others here in New England and beyond. It's been a fun ride to say the least!

Totally off topic, but just wanted to say thanks for your contributions.

I dipped my toe in instrument repair, realized I had neither the talent nor time to do it correctly, and jumped out of the pool as quickly as I could.

We ambivalent archers are constantly blaming our misses on the arrow, thank you for standing up and reminding us your career is as much art as technical effort.

Or maybe I just need another mouthpiece, yeah, that's it, blame it on the mouthpiece.........
