How to clean speaker

You can use 99.9% isopropyl alcohol to aid in clearing out debris from the speaker. Just make sure you turn off and unplug the device then after cleaning leave it for an hour to make sure that all of the alcohol has evaporated (you can use the heat of a hairdryer to help).

To clean the speaker, first turn it off and unplug it. Then, gently wipe the outside of the speaker with a soft cloth or special speaker cleaner. Do not use water or harsh chemicals, as this can damage the speaker. If dust accumulates in the small holes, it is best to clean it with compressed air or a soft brush. Regular use of speaker cleaner will improve the sound of the speaker and increase its lifespan.
