How to Clean Signia Hearing Aids and Restore Sound

Cleaning Signia hearing aids takes just a couple of minutes a day and is the single most effective thing you can do to keep them sounding clear and lasting longer. Ear wax buildup is the most common cause of muffled or weak sound, and a simple daily wipe prevents most problems before they start.

What You Need

Keep a small kit near where you store your hearing aids each night. You’ll want a soft, dry cloth or tissue, a small brush with soft bristles (most Signia models ship with one), and a supply of replacement wax guards that match your specific model. If you wear a behind-the-ear (BTE) style with a thin tube, ask your hearing care professional for a cleaning wire designed to fit the tube. Avoid household cleaning products, alcohol wipes, and any liquid sprays. Signia is explicit: never use running water or immerse the devices in water, and never apply pressure while cleaning.

Daily Cleaning Routine

The best time to clean is right after you take your hearing aids out. Ear wax is still soft at that point and wipes away easily. Once it dries, it hardens and becomes much harder to remove.

Hold the hearing aid over a soft surface (a towel on a table works well) so you won’t damage it if it slips. Gently wipe the entire surface with a soft, dry tissue. Pay extra attention to the ear piece, the part that sits inside your ear canal, since that’s where wax accumulates most. If you wear click domes or click sleeves, squeeze the tip of the ear piece between your fingers to loosen and push out any wax trapped inside. Then wipe it clean.

Use your small brush to lightly sweep across the microphone ports, the tiny openings on the outer casing of the hearing aid. Brush outward, away from the ports, so you don’t push debris deeper into the device. A clogged microphone port can make your hearing aid sound weak or distorted even when everything else is working perfectly.

Cleaning Thin Tubes on BTE Models

If your Signia hearing aid has a thin tube (sometimes called a ThinTube) that loops over your ear and connects to the dome, moisture and wax can gradually build up inside it. You can clear this with a cleaning wire, a thin flexible filament designed for the purpose.

Unscrew the adapter that connects the tube to the hearing aid body. Carefully insert the cleaning wire into the adapter end and push it all the way through the tube. Wipe away any wax or debris that comes out the other end. Pull the wire completely out, then reattach the tube and adapter to the hearing aid. If the tube looks discolored, stiff, or cracked, it’s time for a replacement rather than another cleaning.

Replacing Wax Guards

Most Signia hearing aids have a small wax guard, a tiny filter that sits near the tip of the device to protect the speaker (receiver) from wax buildup. This is a consumable part, meaning it’s designed to be swapped out regularly rather than cleaned and reused.

Check the wax guard every few days by looking at it closely under good light. If you can see wax clogging the tiny holes, or if sound has become noticeably quieter or muffled, it’s time to replace it. Signia uses different wax guard styles depending on the model, so make sure you have the correct replacement for your specific hearing aid. Each wax guard pack comes with a small tool: one end removes the old guard, the other inserts the new one. The whole swap takes about ten seconds once you’ve done it a couple of times.

How often you need to replace wax guards varies a lot from person to person. Some people produce more ear wax than others, and factors like humidity and skin oils play a role. Some users replace guards weekly, others go a month or more. Let the visual check guide you rather than sticking to a rigid schedule.

Replacing Click Domes and Click Sleeves

The soft silicone dome or sleeve at the tip of a receiver-in-canal (RIC) model also wears out over time. It can become discolored, lose its shape, or develop small tears that affect fit and sound quality. Plan on replacing domes roughly every one to three months, or sooner if they look worn.

To remove an old click dome, follow the directions on the replacement packaging. The key safety point is to grasp the dome itself, not the thin receiver cable. Pulling on the cable can damage the wire inside. When attaching the new dome, push it on until you feel and hear it click into place, then give it a gentle tug to confirm it’s secure. A dome that falls off inside your ear canal is an avoidable problem you don’t want.

Click sleeves are a bit different. Turn the old sleeve inside out first, then grasp both the sleeve and the receiver body (again, not the cable) and pull it off. Press the new sleeve on until it clicks noticeably. Double-check the fit before wearing.

Caring for Rechargeable Models

If you have a rechargeable Signia hearing aid, the charging contacts on the bottom of the device need occasional attention. Skin oils, sweat, and dust can coat the small metal contact points and interfere with charging. Wipe the contacts gently with a dry, soft cloth each time you place the hearing aids in the charger. Do the same for the contact pins inside the charging case. If your hearing aids aren’t charging fully or are intermittently disconnecting from the charger, dirty contacts are the first thing to check.

Overnight Storage and Moisture

Moisture is the other major enemy of hearing aid electronics, alongside wax. When you’re not wearing your hearing aids, store them with the battery door open (if they use disposable batteries) in a cool, dry place. A hearing aid drying kit or electronic dehumidifier is a worthwhile investment, especially if you live in a humid climate or tend to sweat. These small containers use either desiccant beads or gentle heat to draw moisture out of the device overnight.

For rechargeable models, the charger itself often serves double duty by providing a dry environment while the devices charge. Even so, wiping moisture off the hearing aids before placing them in the charger helps keep everything in good condition.

When Sound Quality Drops

If your hearing aids suddenly sound muffled, quiet, or distorted, work through a quick cleaning checklist before assuming something is broken. First, inspect and replace the wax guard. Second, clean the dome or sleeve by squeezing and wiping it. Third, brush the microphone ports. Fourth, check the thin tube (if applicable) for moisture or blockages. These four spots account for the vast majority of sound quality issues, and cleaning them often restores normal performance immediately.

If you’ve cleaned everything and the sound is still off, the receiver itself may need professional attention. Your hearing care provider can test and replace it in a short appointment.
