The cleaning process we use for musicalinstruments is not just a simple “dip” or “flush”.
Although we often refer to this process as a“chem clean” it is really much more than that.
We begin with a complete disassembly ofinstrument and first flush out heavy gunk and degrease the instrument.
The entire instrument is submersed indetergents specifically formulated for musical instruments. Ultrasonic sound waves then thoroughly cleaninside and out.
The instrument is them removed from theultrasonic machine and rinsed.
The instrument is then drilled internallywith nylon brushes on an air drill with light grade pumice.
Outside of the slides are hand polished.
Instrument is then reassembled, valves aligned,valves & slides lubricated.
We replace all waterkey corks, & valvefelts.
