Clarinet Care and Maintenance: Daily, Weekly, Yearly
How to assemble, swab, store and protect a clarinet — preventing cracks in wooden clarinets, caring for pads and corks, and when to see a technician.
Updated · Tonehole editors
A well-kept clarinet plays better, stays in tune and costs far less to maintain. Most care takes two minutes a day.
Assembly without bent keys#
- Grease the tenon corks lightly with cork grease when joints feel stiff (not every day).
- Hold joints by the body, not the keys. When joining the upper and lower joints, press the upper ring key down so the bridge key lifts and does not bend.
- Twist gently; never force.
- Put the reed and ligature on last.
After every session#
- Remove the reed, rinse it and store it flat in a reed case.
- Pull a swab through each section (mouthpiece separately) — bell end first, so it doesn't get stuck at the register tube. Two or three passes.
- Wipe fingerprints off the keys with a soft cloth.
- Don't store the clarinet assembled or wet; let the case breathe for a while if it's damp.
- Rinse the mouthpiece in lukewarm (never hot) water once a week.
Wooden clarinets and cracks#
Grenadilla wood cracks when it expands and contracts too quickly. To prevent it:
- Warm the instrument in your hands or under your arm before playing in a cold room; never blow warm air into a freezing clarinet.
- Break in a new wooden clarinet: 10–15 minutes a day for the first week, adding about 5–10 minutes a day over a few weeks.
- Avoid radiators, direct sun and cars. Aim for stable humidity (around 40–60 %). A small humidifier in the case helps in dry winters.
- Swab every time — moisture sitting in the bore is the main cause of cracks near the upper tone holes.
Pads, corks and springs#
- If notes stop speaking, a pad may be leaking. Check by closing keys gently and listening — or have a technician use a leak light.
- Sticky pads can be cleaned with a piece of cigarette paper or pad paper pulled from under the closed pad.
- Never oil the keys yourself unless you know how; a drop in the wrong place attracts dirt.
Annual service#
Take your clarinet to a woodwind technician once a year: they will check pad seating, replace worn corks, adjust springs and oil the mechanism. A full repad is typically needed every several years, depending on use.
How often should I clean my clarinet?#
Swab it after every playing session, wipe the keys and rinse the mouthpiece weekly, and have it serviced by a technician once a year.
Can I wash my clarinet in water?#
Only the mouthpiece (lukewarm water, no harsh soap) and plastic student bodies with the keys removed by a technician. Never submerge a wooden clarinet or any joint with pads attached.
What should I do if my wooden clarinet cracks?#
Stop playing it and take it to a technician quickly. Most cracks can be pinned or banded invisibly if they're fixed before they spread.
