Anything that can get all the gunk out would help. I'll take any advice.

Don't have better idea how to clean it. just use it.

Use a brush to gently clear any debris from the speaker. The brush should be clean and dry and have soft bristles.

toothbrush works, or a small paintbrush, we use those at work and cut the bristles down to about 1/2 inch.

A Q-tip would also be effective at removing an object. Wet a cloth & roll the Q-tip through the wet cloth, which can get the dirt to stick to the Q-tip if you need to.

Airbrush if you have one.
