Whether you are a student heading into band camp or a seasoned professional gigging every weekend, your clarinet is an investment. Proper, routine upkeep doesn't just ensure your instrument sounds its best—it prevents costly repairs down the road.
From preventing cracked wood to stopping sticky keys, here is your step-by-step clarinet maintenance guide to keeping your instrument in peak playing condition.
1. Daily Care: After Every Playing Session
Moisture is the primary enemy of woodwind instruments. Every time you blow air into your clarinet, condensation builds up inside the bore. Left alone, this moisture can warp pads, grow bacteria, and cause wooden clarinets to crack.
Step 1: Remove and Protect Your Reed
Never leave your reed attached to the mouthpiece inside your case. This traps moisture, causes the reed to warp, and creates a breeding ground for mold.
Carefully remove the ligature and slide the reed off.
Wipe off excess moisture with your fingers or a lint-free cloth.
Place it securely inside a humidity-controlled reed case.
Step 2: Use a Pull-Through Clarinet Swab
Swabbing the interior bore is the most critical step in how to cleanÂ
a clarinet.
Disassemble the barrel from the upper joint.
Take a weighted microfiber clarinet swab and drop the string through the bell.
Pull the cloth gently all the way through the instrument. Repeat this 2–3 times until the inside is completely dry.
⚠️ Pro Tip: Never use a regular household cloth or paper towel inside the bore. They can easily get stuck, requiring a professional woodwind technician to extract them.
Step 3: Wipe Down the Keys
The natural oils and sweat from your fingers can slowly tarnish and corrode metal keywork over time. Keep a microfiber polishing cloth in your case and give the nickel or silver-plated keys a gentle wipe down before packing it away.
2. Weekly Maintenance: Deep Cleaning
Once a week, take an extra five minutes to give your instrument a little extra love.
Clean the Mouthpiece
Your mouthpiece collects saliva, lip balm, and food particles.
Submerge the mouthpiece in lukewarm water (never hot water, which can warp or discolor hard rubber mouthpieces).
Use a drop of mild, pH-neutral dish soap and a mouthpiece brush to gently scrub the inside chamber.
Rinse thoroughly with cold water and let it air dry.
Inspect the Tone Holes and Pads
Take a close look at your clarinet pads. Are they water-logged or sticky?
If a pad is sticky or clicking, place a piece of pad cleaning paper (or unsized cigarette paper) between the pad and the tone hole.
Press the key down lightly a few times to absorb the trapped moisture and oils. Do not pull the paper out while the key is clamped down, as this can tear the delicate bladder of the pad.
3. Monthly and Seasonal Care
Apply Cork Grease Sparingly
Clarinet cork grease is essential for smooth assembly, but over-applying it can actually break down the glue holding the corks to the wood.
Apply a thin film of cork grease to the tenon joints only when you feel resistance during assembly.
Twist the pieces together gently; never force a joint.
Wipe away any old, dusty grease buildup from the joints using a soft paper towel before applying a fresh layer.
Seasonal Humidity Control (For Wooden Clarinets)
If you play a professional grenadilla wood clarinet, it is highly sensitive to rapid changes in temperature and weather.
Winter/Dry Climates: Use a case humidifier or two-way humidity control packet (like Boveda) to keep the wood from drying out and cracking.
Bore Oiling: Consult a teacher or technician about applying wood clarinet bore oil once or twice a year during dry seasons to preserve the wood’s natural moisture barrier.
The Golden Rule of Clarinet Storage
Never, under any circumstances, leave your clarinet in a hot car, a cold garage, or next to a heating vent. Extreme temperature swings cause the wood to expand and contract rapidly, which is the number one cause of catastrophic body cracks. Always keep your instrument in a climate-controlled room where you would feel comfortable.
