The earpiece is that thin slot above your screen. It does most of its work pressed against your cheek and ear, which means it collects a mix of skin oil, makeup, sweat and dust. That mix is stickier than normal pocket lint, so it needs a slightly different approach.
Why sound tools don’t reach it
A phone speaker cleaner plays through whichever speaker the browser uses, and that’s almost always the main bottom speaker. On many phones the earpiece also works as a second stereo speaker, so it may get some benefit, but you can’t count on it. For the earpiece, hands-on cleaning is the reliable way.
Start with a dry brush
Use a soft, clean, completely dry toothbrush. Brush along the slot, not into it, with the phone tilted so the earpiece faces down. Short, light strokes. Most of the time that’s all it needs.
Lift the sticky stuff with putty
If there’s visible grime, press a small piece of blue putty lightly onto the slot and lift it straight off. It grabs the oily build-up a brush can’t. Use a fresh side each time.
What about alcohol?
It’s tempting, but liquid can wick through the mesh into the phone. If you want to clean the glass around the slot, put a tiny amount of isopropyl alcohol on a cloth (not on the phone), wipe around the earpiece, and keep it away from the opening itself.
Prevent it from coming back
Wipe the top of your screen with a dry cloth now and then, especially after using makeup or sunscreen. If your screen protector covers the earpiece, swap it for one with a proper cutout.
Check it worked
Make a test call, or use the Left and Right buttons in the speaker sound test with the phone sideways if your phone uses the earpiece for stereo.
