How to clean
Unplug any leads before cleaning the speaker and make sure everything is completely dry before plugging in any USB power source.
Carefully clean the speaker mesh and openings with a dry and soft brush or a cotton swab. The silicone sleeve can be removed and cleaned separately. Gently clean it and the leads with a lint-free cloth, slightly damp with either:
water,
70% isopropyl alcohol, or
75% ethyl alcohol
Important:
do not use any sharp or metal objects.
do not use compressed air.
do not use products containing bleach or hydrogen peroxide.
do not submerge the speaker in any cleaning agents.
