Match the method to the finish: lacquered brass, black nickel and painted finishes all need a light touch, and a plastic trumpet needs only a cloth and mild soap.
Wipe dust off with a soft dry cloth
Start by wiping the whole trumpet with a soft dry cloth to lift dust and fingerprints before any water touches it. Work along the tubing and around the valves and slides, and use the cloth to reach the bell and the leadpipe. A dry wipe keeps grit from scratching the finish when you wash and polish next.
Wash with water and mild soap
Fill a basin or a sink with water and a little mild soap, then set the trumpet in and wash the outside with a soft cloth. Rinse it with clean water so no soap stays on the finish, and let the water drain out of the tubing and slides. Washing lifts the grime a dry cloth leaves behind, and it suits lacquered and painted finishes as well as a plastic body.
Dry every part before you polish
Dry the trumpet right after washing, inside and out, with a soft dry cloth, and leave it standing so water drains from the tubing and slides. Water left on brass can mark the finish, so press the valves and move the slides while you dry them to push water out. Do not put the trumpet in its case while it is still damp.
Buff the finish with a soft polishing cloth
Once the trumpet is dry, buff the finish with a soft polishing cloth, working in small circles along the tubing and the bell. Use the maker's own cleaner when the trumpet ships with it, and follow the instructions on the bottle. Keep the cloth away from the valves and slides, and stop if the finish looks worn or the lacquer starts to lift.
Know when to ask a repair shop
Polishing cannot fix a stuck valve, a slide that will not move, or lacquer that has already lifted, so do not force parts or reach for solvents and abrasives. Take the trumpet to a repair shop for stuck parts, deep scratches, or damage to the finish. A shop can also advise on the right cleaner for a black nickel or painted finish.

Frequently asked questions
How often should I polish my trumpet?
Polish when the finish looks dull or shows fingerprints, and wipe it with a soft dry cloth after playing. Signs to watch are dust and marks on the tubing and the bell, not a set schedule.
Can I use metal polish on a lacquered trumpet?
Use a soft polishing cloth and the maker's own cleaner for a lacquered finish, and keep solvents and abrasives away from it. Metal polish can wear through lacquer, so ask a repair shop if the finish is worn or lifting.
How do I clean a plastic trumpet?
The PAMPET trumpet has a lacquered finish on an ABS body, so the same gentle wash suits it.
