Switch off the subwoofer and unplug it from the power source

Now you can start to clean the subwoofer removing the grill from the front of the speaker. To remove it carefully, pull it off using a thin, flat instrument, then place it on a flat surface so you can clean it later.

There is a possibility that screws will attach some grills; if this is the case, you will need to use a screwdriver to remove the screws.

Use a vacuum cleaner to clean loose dust or debris from the speaker

If you have a vacuum cleaner, you should use it to clean the subwoofer speaker. All you have to do is press the trigger to blow dust and dirt out of the cracks and off the front.

It’s important not to hold the can upside down or sideways because chemicals could squirt out and get into your speaker.

You can also use a soft brush to eliminate loose dust and dirt if you don’t have canned air.

You can use a makeup brush or a paintbrush with soft bristles to clean the dust off the speaker cone and other exposed parts. The pine cones are so fragile; hence, you must be careful when brushing them.

Sprinkle some water on a microfiber cloth

Sprinkle some water on a microfiber cloth and wring it out. Keep immersing a microfiber cloth in clean water until it is completely saturated.

You should squeeze as much water out of it as possible until no more liquid is left.

 If the fabric drips, then it has absorbed too much water. You must squeeze out any excess water until the item is slightly wet.

Ensure you use clean microfiber; otherwise, you will add more dirt to the subwoofer.

Use the slightly damp microfiber cloth to clean the speaker and cone

Use a damp cloth to wipe down the speaker’s cone and exposed parts to eliminate any dust particles or dirt that might still be there in a circular motion. You should clean both the inside and outside of the speaker box.

When cleaning speaker cones, you must be careful and apply the right amount of pressure to wipe away dust and grime. If you don’t, you could end up distorting the cone.

After that, use a dry microfiber cloth to soak up any moisture that might still be there. Use just the right amount of pressure to get rid of all the water around the subwoofer exterior.
