How to clean a woodwind instrument

Every time you play a woodwind, moisture builds up inside from your breath. Left there, it swells pads, loosens cork, dulls the finish, and can grow mold. Most "broken" student instruments are really just dirty ones. A two-minute swab-down after every session prevents nearly all of it.

1. What you'll need

• A cleaning swab (a cloth on a string or weighted cord) sized for your instrument's bore.
• A soft, lint-free polishing cloth for the outside.
• For reed players: a reed guard or case and mild dish soap for the mouthpiece.
• Optional: pad-drying paper, cork grease, and a small brush for hard-to-reach spots.

Avoid harsh chemicals, alcohol on pads or lacquer, and anything abrasive. When in doubt, dry cloth and patience are safest.

2. Swab out the moisture (every time)

This is the single most important habit. Right after you finish playing:

1. Disassemble carefully, twisting gently — never forcing — at the joints.
2. Drop the weighted end of the swab through each section and pull it through to soak up moisture. Pull in the natural direction the swab is designed for so it can't get stuck.
3. Swab the body, then the smaller joints, repeating until the swab comes out only slightly damp.
4. Flute players: use the cleaning rod with a soft cloth threaded through it for each of the three sections.

If a swab ever feels stuck, stop and ease it back the way it came — never yank it through.

3. Mouthpiece and reed care

For clarinet and saxophone, the mouthpiece and reed need their own attention:

• Wipe the reed dry after playing and store it flat in a reed guard so it doesn't warp. Rotating two or three reeds makes them last longer.
• Rinse the mouthpiece in lukewarm (never hot) water with a little mild soap every week or two. Hot water can warp it. Dry it fully before storing.
• Replace a reed once it chips, warps, or stops responding — a tired reed makes everything harder.

4. Protect the pads and corks

The pads that seal the tone holes are delicate and hate moisture. If a pad feels sticky, slip a piece of clean pad-drying paper under it and gently press the key a few times — don't pull the paper out while pressing. A tiny dab of cork grease on the tenon corks keeps joints assembling smoothly and prevents tearing.

5. Wipe the outside and store it right

• Polish gently with a soft, dry cloth to remove fingerprints and oils, especially on a flute's body.
• Let everything dry a moment before closing the case so you're not trapping moisture inside.
• Pack it in its proper case, not loose in a bag — the case shape protects keys and pads from getting bent.
• Store away from heat and direct sun (no car trunks in summer), which can crack wood and warp keys.

6. A quick after-playing routine

1. Swab each section until barely damp.
2. Wipe the reed and store it flat (reed players).
3. Polish the outside with a dry cloth.
4. Pack up in the case, latched, in a cool spot.

Then once or twice a year, take it to a repair technician for a full check of pads, springs, and seals — the same way you'd service a bike or a car.

The real secret: play it often

Here's the honest truth: an instrument that gets played and looked after stays in great shape, and the players who play the most are the ones who enjoy it. That's the idea behind BANDROOM.GAMES: free, retro-arcade games that quietly build real playing skills while you're having fun. Brass Blaster turns hitting the right note on your real, freshly-cleaned horn into a game (saxes and brass supported, transposition handled).
