Hello TM members! I'm getting ready for my very first bath, that is, my first trumpet bath. I've never done this before. I read the following article online and was wondering if you guys could take a peek at the article and let me know if it's sound advice. Many thanks! Roberto [h=3]Bathing the Trumpet[/h]Begin by removing the 3 valves and setting them aside (this is the only component of the trumpet that will NOT be immersed in the bathtub as it could cause corrosion to the springs and felt). Then remove all other slides and caps from the horn, including the first, second and third valve slides, tuning slide, mouthpiece, and the three caps on the bottom of the valve casings. Some third valve slides have 2 movable parts and in this case they should be taken apart and placed in the water separately. Place a washcloth or small towel on the bottom of a clean tub (to prevent the instrument from being scratched) and fill the tub1/3 of the way (or until the bell of the horn is covered) with lukewarm water and a little bit of dishwashing liquid. Lay all the parts of the horn on the cloth in the tub and let soak for 10-15 minutes. While the horn is soaking take the valves and set them upright in a drinking glass with about 2/3 water and 1/3 vinegar. Fill the glass only as high as the springs on the sides of the valves and be careful not to get the felt around the top of the valve wet. After the horn is done soaking, run the long snake brush through the lead pipe and slides several times. Then do the same with the valve brush to clean out the valve casings and the mouthpiece brush to clean out the mouthpiece. A cotton swab can be used as a substitution for a mouthpiece brush. Once all the tubing has been thoroughly cleaned, drain the tub and run clean water through the horn at all angles to rinse out any soap residue. Set each part on a dry towel to air-dry. After the valves have soaked in the water and vinegar mixture for about 20 minutes, remove them and use one of the brushes or a cotton swab to wash away any build-up on the exterior of the valves or in the valve holes. Rinse thoroughly with warm water and set on dry towel to air-dry. Once the horn has dried, reassemble all the parts beginning with the slides and finishing with the valves. Use a dab of slide lubricant when replacing the slides and a few drops of valve oil on each of the valves, wiping away any excess. A good substitute for slide lubricant is Vaseline. Once the horn is intact, the polishing cloth can be used to rub away watermarks and tarnish. One side note, be very careful when handling all the pieces of the horn through the cleaning process. A dent in the wrong place, especially on a valve casing, can render your horn unusable or make the valve action very sluggish.
