How to Clean a Hearing Aid Dome: Step-by-Step Guide from an Audiologist

As an audiologist who has fit hundreds of hearing aids, one of the most common questions I hear is: “Do I need to replace domes every time, or can I clean them?” The good news is that cleaning is safe — and it can extend the life of your domes while keeping your hearing aids performing their best.

At first, I recommend patients simply brush off dirty domes to get used to their new devices. But once you’re comfortable, deeper cleaning methods can save you money and prevent sound problems. Below, I’ll walk you through the exact process I teach in clinic.

Why Dome Cleaning Matters

Dirty domes can block the hearing aid’s wax trap, muffling sound or even making your devices stop working. Keeping domes clean means:

• Clearer, more consistent sound quality
• Longer-lasting wax guards and domes
• Fewer emergency visits for hearing aid maintenance
• Less daily frustration and more confidence wearing your hearing aids

How to Deep Clean a Hearing Aid Dome

Follow these six simple steps to fully clean your dome:

Step 1: Remove the Dome

Gently peel the dome off the hearing aid receiver by pulling at an upward angle. If you’re unsure, use a dome removal tool for better grip.

Step 2: Brush or Wipe the Dome

Using a hearing aid cleaning brush or lint-free cloth, gently remove all visible debris from both the outside and inside of the dome. Flip it inside out to clean more thoroughly.

Step 3: Sanitize with an Alcohol Wipe

Wipe down the dome with an alcohol pad to disinfect the surface and remove oils and bacteria. This step is especially helpful if you wear your hearing aids all day or have oily skin.

Step 4: Optional Soap Wash

If the dome feels sticky or coated, rub it gently between your fingers with a drop of dish soap. This removes earwax oils for a deeper clean. Be sure to rinse thoroughly afterward.

Step 5: Rinse

Rinse the dome under lukewarm water. Cover the drain with a cloth or stopper so you don’t lose the dome accidentally.

Step 6: Dry Thoroughly

Dry the dome completely using a clean cloth. Letting it air dry for at least 30 minutes — or overnight — helps prevent moisture damage to the hearing aid receiver.

When Should You Replace the Dome?

Even with regular cleaning, domes aren’t meant to last forever. Replace them every 1–2 months, or sooner if they become cracked, discolored, or loose. For a full breakdown, see our guide on how often to change hearing aid domes.

Final Tips for Success

• Keep an extra pack of domes and wax guards on hand (hearing aid accessories guide)
• Clean your domes at least once a week, or more often if you produce heavy wax
• If sound suddenly seems muffled, try cleaning before replacing
• Ask your audiologist to check domes during regular appointments

Frequently Asked Questions

Can I reuse hearing aid domes?
Yes, domes can be reused if they are cleaned properly. However, they should still be replaced every 1–2 months, or sooner if they are cracked or discolored.

How often should I clean my hearing aid domes?
At least once a week, or more often if you produce heavy earwax. Cleaning prevents clogged wax guards and muffled sound.

Can cleaning damage the dome?
No, as long as you follow safe steps (gentle brushing, mild soap, alcohol wipes, full drying). Avoid boiling water, bleach, or harsh chemicals, which can damage domes.

What’s the difference between cleaning and replacing?
Cleaning removes wax and oils to extend dome life. Replacement is necessary when domes are cracked, stretched, discolored, or no longer fit securely. See our guide on when to change hearing aid domes for details.
