Whether you are a student setting up for concert band or a professional flutist prepping for a orchestral audition, your flute requires precise care. Because the flute lacks cork joints and reeds, its mechanism is highly delicate. Sweat, skin oils, and internal moisture can quickly deteriorate your pads and cause sluggish key action.
Prevent sticky keys and tarnished silver with our step-by-step flute maintenance guide to keeping your instrument responsive and beautiful.
1. Daily Care: After Every Playing Session
Moisture is public enemy number one for woodwind instruments. Every time you play, warm air creates condensation inside the tube. If left inside, this moisture breaks down the delicate skin of the flute pads, leading to leaks and expensive repair bills.
Step 1: Use a Cleaning Rod and Swab
Swabbing the interior is the most vital step in how to clean a flute.
-
Take your flute cleaning rod and thread a corner of a lint-free cotton or silk flute swab through the eye of the rod.
-
Wrap the cloth over the top of the rod so the hard plastic or metal tip is completely covered (this prevents you from scratching the inside of your instrument).
-
Carefully insert the rod into each section—the footjoint, body, and headjoint—and gently twist to absorb all trapped moisture.
Step 2: Clean the Flute Headjoint and Embouchure Hole
The headjoint collects the most moisture and condensation. Pay special attention to the embouchure hole (the blow hole). Wipe the lip plate down to remove facial oils, makeup, or lip balm that can corrode the finish over time.
⚠️ Pro Tip: Never insert anything inside the headjoint other than your cleaning cloth. Pushing objects into the top of the headjoint can shift the headjoint cork, throwing your entire instrument completely out of tune.
Step 3: Wipe Down the Exterior
The natural oils from your fingers react with air to cause silver tarnish.
-
Use a dry microfiber polishing cloth to wipe down the body and keys after every use.
-
Avoid using liquid silver polishes or treated polishing cloths directly on the keys, as the chemicals can seep into the pads and ruin them.
2. Weekly Maintenance: Key and Pad Care
Take a few minutes once a week to inspect the moving parts of your instrument.
Fix Sticky Flute Keys
Are your keys clicking, sticking, or slow to rise? This is usually caused by a buildup of saliva and dust on the pads.
-
Take a sheet of flute pad cleaning paper (or unsized cigarette paper).
-
Place the paper between the sticky pad and the tone hole.
-
Lightly press the key down a few times.
-
Release the key before sliding the paper out to prevent tearing the delicate pad skin.
Keep Liquids Away
Unlike a clarinet or saxophone mouthpiece, you should never wash any part of your flute with water. Submerging a flute headjoint or body will instantly destroy the pads and rust the steel needle springs that hold the mechanism together.
3. Long-Term and Seasonal Care
Do Not Oil the Mechanism Yourself
It can be tempting to buy flute key oil and apply it to sluggish keys. However, the tolerances in a flute mechanism are incredibly tight. Over-oiling attracts dust, creating a gritty paste that can permanently jam your keys. Leave mechanism oiling to a certified woodwind repair technician during your annual tune-up.
Safe Assembly and Storage
-
Assemble with care: When putting your flute together, never grab the keys. Squeezing the key mechanism while twisting the joints can easily bend the long steel rods. Always hold the flute by the blank spaces on the tubing.
-
Keep it cased: Never leave your flute sitting out on a bed, chair, or floor where it can be stepped on or knocked over. Even a microscopic bend in the body tube can cause multiple keys to leak.
