How to clean and oil your plastic trumpet from TROMBA (or Allora)

This blog shows you how to clean and oil your plastic trumpet. We are showing the TROMBA (also called Allora in the USA), but you can follow these instructions for any brand of plastic trumpet or any brass trumpet since the steps will all be the same.

1. Take it apart and put all parts in a sink or bucket.
2. Fill the sink with warm, soapy water. I recommend a clear dish-washing liquid.
3. Use the flexible snake to clean all the tubing on the body of the instrument.
4. Use the flexible snake to clean all the tuning slides. Don't try to force the snake around the tight bends of the smaller slides.

5. Scrub the valve casings with the straight brush. Use extra soap on the brush to clean inside the casings.
6. Scrub the valve surface with the straight brush, using plenty of soapy water. Clean the valve ports with the tapered brush. While you are at it, also clean the mouthpiece with the tapered brush.

7. Rinse all the parts and let them dry.
8. Use Ultra-Pure Regular Tuning Slide Lube to grease all the slides and put them back into the body of the instrument. Also, put the bottom valve caps back on the horn.
9. Use Ultra-Pure Professional Valve Oil to oil the valve surface. Use enough oil to coat the valve, about 3 to 5 drops.
10. When you put the valves back into the casings, note that they have numbers (1, 2, 3) on the valve stems. There is a valve guide that has a wide and narrow part and will fit into the casing in a matching wide or narrow slot. Note that on the TROMBA or Allora trumpet, the 1st and 2nd valves have the narrow valve guide on the bell side, but the 3rd valve is opposite and has the narrow valve guide on the leadpipe side. This picture shows the numbers on the valve stems.
11. After everything is back together, blow some air through the horn and press each valve. If the air stops, then one or more valves are in backward.

A note about the break-in period for valves

The valves on your new plastic trumpet might be a bit stiff and slow. This is normal for a new student trumpet since the valves are not so perfectly fitted at the factory. You will have to wipe off the valves and swab the valve casings every day to clean off metals that are wearing down due to friction. Use plenty of valve oil during the break-in period. After a week or two of doing this and giving the horn a really good cleaning, the valves should feel fine and will move easily and quickly. You will know when they are broken in when there is no more black residue on the valves.

Purchase our basic lube kit. It comes with a bottle of Ultra-Pure Professional Valve Oil and a jar of our Regular Tuning Slide Lube.
