We have an article on how to clean your AirPods that also applies to other earbuds. But if you don't want to read that, the condensed version is this: Wipe down both the buds themselves and ear tips with a slightly dampened soft, dry, lint-free cloth (like the kind you use to clean glasses or your phone's screen) and avoid using any soap or harsh cleaning liquids. A 70% isopropyl alcohol wipe or a Clorox disinfecting wipe is OK but avoid getting too much moisture in any ports or inside the buds themself. You can also use a toothpick for any little crevices or a Q-tip with a bit of alcohol on it. Avoid saturating the Q-tip with alcohol. Finally, wait a few minutes until any moisture evaporates before using the buds.
