    What would be a good (not so expensive) way of getting the green mold/rust out? My cleaning brush doesn't work. Is there a special soap I can buy that would help me? :play:

    Do you use pure vinegar or is it diluted with water?

    Vinegar may work on mold removal.

    However, if you see some foreign material inside your horn that normal soap and a scrub brush does not remove then it is almost certainly a mineral deposit.

    You are going to need something stronger than vinegar to remove a mineral deposit.

    I have used a couple different cleaners with success. One was a mineral remover I picked up at the hardware store that was made for cleaning humidifiers. It contained a weak form of HCl. A second is a mineral remover I picked up at a local farm supply store.
    It is an acid also, not sure what forumla.

    The important thing with using these is to actually observe what you are doing.
    First, get a pen light, or something that lets you see the inside of your horn.
    When your horn is clean and dry, the inside should be shiny. It may have oxidation of various colors, which is typical for brass, but it should be smooth and shiny.

    If it isn't, you've got mineral deposits.

    So here's what I do:

    1) Clean the slide (or other pipe that's dirty) with mild soap and water and a brush
    2) Dry it
    3) Inspect for remaining debris
    4) If debris (minerals) remain then fill the slide with your mineral remover.
    Be careful not to get it on the external finish or your hands
    5) Let it sit for 5 to 10 minutes
    6) Dump the acid and rinse the slide
    7) Wash the slide with mild soap and water using brush
    8) Rinse and dry

    Your slide whould be nice and clean. If not then GRADUALLY increase the amount of time the acid sits in the slide.

    Do NOT place your whole horn in an acid bath or anything else for that matter besides water. Chemical based cleaners that work by soaking will not only remove gunk but will take some of your brass and/or finish with them.

    Hope this helps,

    Greg

    Would a typical chem or ultrasonic clean from a brass shop do the trick?

    Here's what my teacher does and what I do.

    I take the horn, stick a pipe into the whatever-it's-called-in-English where you put your mouthpiece. Set some pressure on the pipe and flush hot (not very hot though, or you'll know what happens) water through the pipe. It does not damage the horn in any way, only gets rid of the mold and other annoying stuff with pure pressurised water flow. Works like a charm to me.

    Let's just back up the truck a bit - vinegar is the preferred solution for cleaning vacuum toilets on large Boeing and Airbus aircraft. These toilets gather crap (literally) from hundreds of sources, filled with all kinds of internal chemicals, bacteria, viruses, fats, acids, Kranzkys, Vegemite sandwiches and stuff. Where the waste products slow down in the extraction system then the mineral deposits build up - until we hit it with vinegar.

    Vinegar dissolves all the hard deposits and most of the soft ones too. Where there is a problem with excessive build-up then we allow vinegar to soak awhile (is this sounding familiar) and send a charge of dry ice down the toilet's Supesonic Sh*t Shute (yeah yeah - chute) to abrade the really difficult stuff away - works like a charm on hundreds of airplanes around the world probably every day - so why not a trumpet? :cool:

    Vacuum toilets work on differential pressure, essentially like a trumpet, (even sometimes the sounds are similar) and any scale in your trumpet has got to be loads less 'problematical' than the waste service in your average airplane.

    I say go with the vinegar - it is a great natural cleaner. :thumbsup:

    Thanks ted for the explanation. I now know for sure that the vinegar will clean my trumpet.

    RAK, please don't think I am decrying what Greg, and the others have said to you - their comments are very valid - I just know a bit about how successfully vinegar cleans stuff out of air tubes (and you all thought I just knew about Rolls Royce Gas Turbine Engines, hah!). ROFL
