Chemical Cleaning

Firestas'1 · 02-12-2008, 05:06 PM

Hello fellow TMers,

Everyone has heard of having horns "chemically cleaned", does anyone know what chemical is used and how it is applied?

Just wondering.

100% SULFURIC ACID !

Just kidding, I typically have my horns ultrasonically cleaned.

wouldn't worry about it. people have been using chemical cleaning for years

Chemicals used in shops are either a type of industrial soap for horns that aren't full of calcification, and they used to use muriatic (sp) acid, but now they use something else. At the school I go to it is called Etch-Klenz.
Better equipped shops will use an ultrasonic. They are great, it takes only 2 minutes or so to do an entire horn.

I have heard that sodium cyanide was used as a cleaner.

If I remember correctly, muriatic acid isn't used any more because it contained cyanide.

The store I used to work at used muriatic acid. That was about three years ago, they could have changed by now.

Thanks Brekellefuw.

So they just dump it down the bell and let it run through?

Muriactic Acid = Hydrochloric Acid (in aqueous solution)

We have large tubs of it. we disassemble the trumpet and then submerge it and scrub the inside with brushes.
