How to Clean a Harmonica

Introduction

A harmonica can accumulate saliva, moisture, and debris over time, which affects both hygiene and sound quality. Regular cleaning helps extend its life and keeps it playing smoothly.

What You'll Need

• Lukewarm water

• Soft toothbrush

• Mild dish soap

• Microfiber cloth

• Isopropyl alcohol (optional, for outer surfaces only)

• Small container

Steps

Rinse the harmonica under lukewarm running water to remove loose debris.
Fill a small container with warm water and a drop of mild dish soap.
Gently scrub the cover plates and mouthpiece with a soft toothbrush.
Rinse again thoroughly to remove all soap residue.
Shake out excess water and wipe the exterior with a microfiber cloth.
Allow the harmonica to air-dry completely before storing or playing.

Alternative Methods

• Use isopropyl alcohol on the outer metal surfaces for sanitizing (avoid internal reeds)

• Use a harmonica-specific cleaning spray designed for delicate reeds

• Disassemble the harmonica—only if manufacturer-approved—to clean each part individually

What NOT to Do

• Do not soak a wooden-comb harmonica, as it can swell and become damaged

• Do not use boiling water or harsh chemicals

• Do not scrub reed plates aggressively, which may bend the reeds

FAQs

How often should I clean my harmonica?

Light cleaning after each use is ideal, with a deeper clean every few weeks if you play frequently.

Can I fully submerge my harmonica?

Only harmonicas with plastic or metal combs can be briefly submerged. Wooden-comb models should never be soaked.

Is it safe to disinfect the inside with alcohol?

No—alcohol can damage reeds. Only use it on exterior surfaces.
