We recommend an acid bath at least once a year to keep your low brass instrument playing well, and to prevent more costly repairs such as soldering or stuck slides.
Our custom acid bath process is much more than meets the eye. We begin by fully disassembling and cleaning off all old oils and greases from the parts. The instrument is then dipped in our mild and environmentally friendly acid, which mainly loosens the corrosion on the parts as well as treating the metal. After a few minutes, the instrument is rinsed and all parts are cleaned with a special pumice based soap. We use brass and nylon bristle brushes that leave the casings and slides polished clean as new. The instrument is then further cleaned to remove all debris that has come off in this process. We re-oil and grease all parts, check your felts and waterkey corks and replace if needed, and adjust spring tensions. Finally we play test the instrument to ensure your horn is playing at it’s best.
Bring in your low brass horn for a free estimate if your instrument is overdue for this important servicing.
