How to Safely Clean iPhone Speakers
(Top & Bottom Grills)
Is your iPhone volume lower than it used to be? It’s likely not broken. Here is the technician-approved guide to removing wax and lint without destroying your water resistance seals.
If you own an iPhone 12, 13, 14, or 15, you have likely noticed a gradual drop in call volume or music clarity.
The problem lies in the design. The iPhone uses incredibly fine mesh grills to achieve its IP68 Water Resistance rating. While this mesh keeps water out, it is also perfect at trapping:
- Sebum (Face Oil): Transfers from your cheek during calls.
- Dead Skin Cells: Accumulates in the top ear receiver.
- Pocket Lint: Gets jammed into the bottom firing speakers.
When these three mix, they create a waxy “cement” that hardens over the mesh. Sound waves cannot penetrate this wall, leading to the dreaded “muffled voice” effect.
⚠️ STOP! Don’t Use These Tools
Before you grab a tool from your kitchen drawer, read this. Using the wrong tool can permanently ruin your $1,000 device.
Why it’s dangerous: The iPhone microphone and speaker diaphragms are extremely sensitive. The high pressure from canned air can shatter these membranes. Worse, it blows dust inside the phone chassis, potentially blinding the FaceID sensors or camera.
Why it’s dangerous: The mesh protecting your speaker is made of fabric or fine metal. A sharp pin will puncture this mesh instantly, destroying your phone’s water resistance forever.
Why it’s dangerous: Harsh chemicals dissolve the adhesive that holds the screen to the body. Only use 70-99% Isopropyl Alcohol if absolutely necessary.
Method 1: The “Blu Tack” Press (Best for Bottom Ports)
This is the secret weapon used by repair technicians. Adhesive putty (brands like Blu Tack or Fun-Tak) is sticky enough to grab dirt but solid enough not to leave residue.
Step-by-Step Instructions:
- Warm the Putty: Tear off a pea-sized chunk of Blu Tack. Roll it between your fingers for 60 seconds. The warmth makes it stickier and more malleable.
- Form a Cone: Shape the putty into a blunt cone or thick sausage.
- The Press: Firmly press the putty into the bottom speaker holes (on the right side of the charging port). Press hard enough so it molds into the holes, but not so hard that it breaks off.
- The Quick Snap: Pull the putty away quickly. You will see black gunk, lint, and grey dust attached to the blue surface.
- Repeat: Fold the putty to a clean side and repeat until the holes look black and empty.
*Pro Tip: Do not use this method on the top “Ear Receiver” mesh, as the mesh is looser and putty can get stuck inside.*
Method 2: The Soft Brush (Best for Top Speaker)
The top speaker (where you put your ear) gets clogged with oils. Putty won’t work here because the debris is usually sticky/waxy. You need mechanical action.
Tools Needed:- A soft-bristled toothbrush (Clean & Dry)
- Optional: 99% Isopropyl Alcohol (Not 70%, fewer water content is better)
The Technique:
Step 1: Gravity is Your Friend
Hold your iPhone upside down. This is crucial. You want the loosened dirt to fall out of the phone, not deeper into the grill.
Step 2: The Angle Scrub
Brush the top grill gently at a 45-degree angle. Use short, flicking motions rather than a heavy scrub. Think of it like “sweeping” a floor.
Step 3: The Alcohol Dissolve (Advanced)
If dry brushing doesn’t work, dip the very tips of the bristles in Isopropyl Alcohol. Shake the brush off so it is barely damp. Brush the mesh again. The alcohol dissolves the face oils that glue the dirt together.
Why doesn’t the left side work?
We get this email constantly: “I cleaned my speakers, but the holes on the bottom left still have no sound!”
Don’t panic. Your iPhone does not have two bottom speakers.
• Bottom Right Holes: This is the Main Loudspeaker.
• Bottom Left Holes: This is the Barometric Vent and Microphone. It is supposed to be silent. Do not try to jam cleaning tools in there aggressively—you might damage the mic.
Method 3: The “Late Night” Volume Hack
If your speakers are physically clean but the volume still feels weak, Apple has a hidden setting that can boost perceived loudness.
- Open Settings.
- Scroll down to Music.
- Tap on EQ.
- Select “Late Night”.
The “Late Night” EQ compresses the dynamic range. It lowers the loudest booms but significantly raises the volume of quiet vocals, making podcasts and videos sound much louder on small speakers.

iPhone Cleaning FAQ
My iPhone got wet and sounds crackly. Should I clean it?
If it’s wet, do not use putty or brushes yet. You need to eject the water first. Cleaning a wet mesh will just push the water deeper. Use our Water Eject Tool first, let it dry for 2 hours, and then clean the residue.
Does cleaning the speaker void my warranty?
No, regular cleaning does not void warranty. However, if you puncture the mesh with a needle or trigger the Liquid Contact Indicator (LCI) by using too much wet alcohol, Apple may deny your warranty claim.
How often should I clean my iPhone speakers?
We recommend a “Light Clean” (Toothbrush only) once a month to prevent build-up. A “Deep Clean” (Blu Tack method) should only be done when you notice a drop in volume.
