Keeping your instrument clean and in good working condition is an important part of being a musician, whether you are a beginner or a professional. Cleaning a trombone is easy to do yourself and should be done on a regular basis. How often should your trombone be cleaned and what methods should be used?
Cleaning a Trombone Before and After Playing
There are a few things you should be cleaning regularly on your trombone, especially before and after you play. Keeping up with these cleaning tasks will keep your trombone in great condition and may help you notice small repair issues before they become bigger problems.
Before You Play
Start by getting a soft, lint-free cloth. Using an old T-shirt you no longer wear will work great, just be sure it is clean. You will also need a cleaning rod. Put the cloth on the end of the rod, covering the end completely to avoid scratching or denting, and insert it into the outer tubes, swabbing it several times until you feel the tube getting warm. Do both tubes this way. Once you’ve cleaned the inside, wipe down the inner side with a separate cloth. Before you reinsert the slide, apply slide oil to re-lubricate the area you cleaned.
Oil the Rotary Valve
You will also need to apply rotor oil to the rotary valve through the slide receiver if you are using a tenorbass or bass trombone.
Clean the Slide After Playing
When you are finished playing, you will need to do another round of cleaning. Start by opening the water key to let any moisture out from inside the slides. Using a polishing gauze wrapped around your cleaning rod, clean the inner and outer slides. Be sure nothing is left behind inside the tube and always brace the slide when cleaning, so you don’t accidentally bend the tubes.
Clean the Exterior
Once you are finished playing, you should also clean the exterior of your trombone. This will remove any oil from your fingers, dirt, grime, or anything else that may be on the surface that could wear away at the finish if left for long periods of time. Cleaning a trombone exterior is simple. Use a polishing cloth and gently wipe the entire exterior surface. For lacquered trombones, you can also use a lacquer polish every once in a while to give it a nice shine. If your trombone is nickel-plated, you can use a metal polish to restore the metal’s luster.
Cleaning The Mouthpiece
Don’t forget to clean your mouthpiece! To do this, simply use warm water and a mild liquid soap. Gently scrub with a mouthpiece brush and rinse clean. You can do this every few days or once a week, depending on how much you play.
Cleaning a Trombone Monthly
While keeping your trombone clean before and after each time you play is key, you will also need to do a more thorough cleaning about once a month. Depending on how often you play, you may only need to deep clean your trombone every 3 months. Believe it or not, you should clean your trombone in the bathtub.
Step 1: Take Your Trombone Apart
If this is your first time taking your trombone completely apart, be sure you are familiar with its anatomy so you can reassemble it properly when you are finished cleaning it. You could record yourself taking it apart so you can reference it later. You will end up with 5 major pieces including the bell, tuning slide, main outer slide, main inner slide, and mouthpiece. Trigger horns and bass trombones may also have additional attachments and tuning slides. As you take your trombone apart, place each piece on a towel or another soft surface to avoid dents or scratches.
Step 2: Soak Your Trombone Pieces in the Bathtub
Fill your bathtub with warm water and add some mild dish soap. If you have another large container, you can use that instead. Lay another towel on the bottom of the tub, so your trombone has a soft surface to rest on. Submerge each piece of your trombone in the water and allow them to soak for around 10 minutes.
If you don’t have a bathtub: Some homes don’t have bathtubs and that’s okay! You can also rub warm water through the trombone pieces while cleaning it.
Step 3: Start Cleaning Your Mouthpiece
While the main part of your trombone soaks, you can start by cleaning the mouthpiece. You can use the same method mentioned above and simply use warm water, mild soap, and a gentle brush. Never use any harsh cleaners such as bleach since these could strip the finish from the metal. Set it aside to dry when you’re finished.
Step 4: Start Cleaning Inner Surfaces
Begin cleaning the inner surfaces using a snake and a cleaning rod. Run the snake through the inside of the tubes to break up any stubborn deposits that were loosened by the warm water soak. The cleaning rod wrapped in a cloth can be used on straight pieces that may have more stubborn deposits. Then run clean water through the tubing to flush out leftover soap, remove it from the bathtub, and lay it back on the soft, dry surface. Repeat this for each of the separate trombone pieces.
Step 5: Start Cleaning Outer Surfaces
Now that the inside of each piece has been cleaned, you can clean the outside of the trombone. The main inner slide and tuning slide are going to be two areas to focus on. These surfaces can have a lot of build up from slide grease and oil over time. Use a soft, lint-free cloth to wipe the surfaces clean. If this isn’t enough, you can apply a small amount of mild soap to the cloth and wipe until clean. Using a brush over the tuning slide may also help remove any mineral buildup. Rinse the outer surfaces with clean water and hand dry them with a soft, clean cloth.
Step 7: Allow Time to Dry
After cleaning a trombone, you will need to allow time for it to air dry. This will take at least 30 minutes.
Step 8: Lubricate Your Trombone
Start by applying lubricant to the inner slide and stockings. Work on one end at a time. Once the lubrication is covering the area, spray the slide with some water. Now you can lubricate the tuning slide using slide grease.
Step 9: Reassemble Your Trombone
Put your trombone together just as if you were going to play it. If you recorded yourself taking it apart, rewatch the video to ensure you are reassembling it properly. When putting your trombone back together, never try to force pieces into play. If something doesn’t seem right, it probably isn’t. Once everything is back together and working smoothly, try playing a bit to make sure it sounds correct as well.
