If your trumpet has gotten really funky, go buy a trumpet cleaning brush (long flexible spring with brushes on the ends). # Pull out all of the slides and the valves. # Set your valves aside and take the rest of the trumpet to the kitchen sink (while your mom's not watching). # Soak the horn in warm soapy water for a few minutes and pull the brush through all of the tubing. # Rinse everything really well in cool water, let it dry and grease all of the slides and reassemble. # Wipe your valves down with a dry cotton cloth and put a couple drops of valve oil on them and reassemble them into the horn. # Last thing: go clean the funk out of the sink.
Trumpet
To clean a trumpet effectively and maintain its performance and longevity, you should regularly clean the mouthpiece, valves, and slides with a cleaning kit designed for brass instruments. Use lukewarm water and mild soap to clean the trumpet, avoiding harsh chemicals. Dry the trumpet thoroughly after cleaning and store it in a protective case when not in use. Regular maintenance and cleaning will help prevent build-up of dirt and debris, ensuring the trumpet plays well and lasts longer.
To clean your trumpet effectively, disassemble it and soak the parts in warm, soapy water. Use a cleaning snake to remove any debris from the tubing. Rinse the parts thoroughly and dry them completely before reassembling the trumpet. Wipe down the exterior with a soft cloth and polish if desired.
Regular or soft dish soap will be fine to use on your stainless thermos. You can also soak the thermos in bleach after you clean it with dish soap just to make sure you have gotten all of the germs out. Make sure you soak it in water after the bleach; dont drink bleach.

Soap is simple to use for cleaning
To effectively clean an old trumpet, first disassemble it by removing the valves and slides. Soak these parts in warm, soapy water and use a cleaning brush to scrub away any dirt or grime. Use a valve casing brush to clean the inside of the valve casings. Wipe down the trumpet body with a soft cloth and polish it with a brass polish. Reassemble the trumpet and oil the valves before playing.
