Learn how to properly clean and maintain your Etymotic ER38-47 Cleaning Brush to keep your earphones and eartips in top condition. Simple steps for long-lasting performance.

Quick answer

To clean your ER38-47 Cleaning Brush, rinse the brush head under warm water after each use, gently remove debris with a soft cloth, and let it air dry completely before storing.

Why regular cleaning matters

Earwax, dust, and debris naturally accumulate on earphone brushes and eartips. A dirty brush can transfer grime back into your earphones or eartips, reducing sound quality and hygiene. The ER38-47's loop and magnet design makes debris removal easier, but the brush itself needs periodic cleaning to stay effective.

Step-by-step cleaning guide

1. Rinse the brush head: Hold the brush under lukewarm running water for 10-15 seconds. Avoid hot water as it may soften the bristles. Do not use soap or solvents; water alone is sufficient for routine cleaning.
2. Remove stubborn debris: Gently wipe the bristles with a soft, lint-free cloth or your fingers to dislodge any wax or particles. The loop and magnet can help pick up metal fragments from earplugs. Never use sharp objects or excessive force, which can bend or break the bristles.
3. Dry thoroughly: Shake off excess water and place the brush in a well-ventilated area to air dry completely. This prevents mold or bacteria growth. Do not store the brush while damp; moisture can damage both the brush and your earphones.
4. Inspect and store: Check the brush for damage or wear. Store it in a clean, dry place away from direct sunlight. Replace the brush if bristles become frayed or loose. A worn brush may scratch eartips or fail to clean effectively.
