Your airpods need regular cleaning to perform well and last longer. Here's the safe way to do it without damaging sensitive components.
Use a soft, dry, lint-free cloth to wipe down the exterior of each AirPod. Don't use liquids on the AirPods themselves.
Use a dry cotton swab to gently brush the speaker mesh on each AirPod. For compacted earwax, use Blu Tack pressed gently against the mesh.
Use a wooden toothpick or soft-bristled brush to carefully clear debris from the microphone and sensor openings.
Wipe the case with a cloth slightly dampened with 70% isopropyl alcohol. Use a dry cotton swab to clean inside the case and the Lightning/USB-C connector.
