TL;DR
Hearing aid domes and wax guards are consumables, replaced on a schedule rather than deep cleaned, and everything is done with dry tools. Most audiologists suggest checking the dome daily and replacing a wax guard when sound drops or every few weeks. Water and cleaning liquids stay away from the electronics entirely.
Dry tools only, always
The single most important rule with hearing aids is that water and the device do not mix. That includes tap water, alcohol wipes, cleaning sprays, and anything else in a bottle.
Modern hearing aids carry moisture resistance ratings, but resistance is not immunity. Liquid that reaches the receiver, the microphone ports, or the battery contacts can end the device.
The cleaning kit that came with the aids is what you use: a soft dry brush, a wax pick or loop, a soft dry cloth, and the wax guard replacement tool. If your kit went missing, your audiologist sells another one.
How do you clean hearing aid domes?
Take the dome off the receiver wire, wipe it with a dry soft cloth or a tissue, and clear the sound opening with the brush from your cleaning kit, working from the inside outward so debris falls away rather than in. Inspect the dome, and replace it if it is discolored, stiff, split, or will not come clean dry.
Domes are inexpensive silicone consumables. Most people replace them every one to three months, more often if wax production is heavy. Your audiologist stocks the size and style your aids use.
Do not rinse a dome under the tap and put it straight back on. A dome that goes back wet carries water directly into the receiver opening. If a dome ever gets damp, let it dry completely away from heat before it goes back on the aid.
Wax guards are replaced, not cleaned
A wax guard is a tiny filter that sits at the sound outlet and keeps earwax out of the receiver. It is designed to fill up. That is its job.
You do not clean a wax guard. When it plugs, you swap it. Most manufacturers ship a replacement tool with a double-ended stick: one end pulls the old guard out, the other seats a fresh one.
The usual signal that a guard needs changing is a sudden drop in volume, a muffled sound, or one aid going quiet while the other sounds normal. Before you assume a repair, change the guard.
Replacement intervals run anywhere from every couple of weeks to every couple of months, depending on how much wax the ear produces. Some people change them monthly on a calendar and never think about it again.
The daily routine that prevents most problems
Five minutes a day keeps hearing aids working and cuts down on service visits.
Each morning, before you put them in. Wipe the shells and receiver wires with a dry soft cloth. Brush the microphone ports gently. Look at the domes for anything visible.
Each evening, when they come out. Wipe them down again while any moisture from the day is still on the surface. Open the battery door on models that use disposable batteries, or seat rechargeables in their charger.
Weekly. Look closely at the domes and wax guards in good light. Replace whatever looks used up. Wipe down the charger contacts with a dry cloth.
A drying container or electronic dehumidifier is worth having, especially in a damp climate or for anyone who sweats heavily. It draws overnight moisture out of the aids without any liquid involved.
What to keep away from hearing aids
- No water, alcohol, or cleaning sprays on the aids themselves.
- No wipes, including alcohol wipes and disinfecting wipes, unless your audiologist specifically supplies them for that purpose.
- No hair spray, sunscreen, or lotion on the aids. Put the aids in after those go on, not before.
- No hair dryer, oven, microwave, or radiator for drying. Heat destroys the electronics.
- No pins, paper clips, or toothpicks poked into a sound opening. That pushes wax deeper and can puncture a receiver.
- No shower, pool, or sauna. Take them out.
If an aid does get wet, remove any disposable battery, leave the battery door open, and get it to a drying container. Then call your audiologist. Do not try to speed it up with heat.
When to call the professional
Cleaning and dome or guard replacement are the parts you own. Everything else goes to an audiologist or hearing aid dispenser.
Call them if sound is still weak after a fresh wax guard and a new dome, if there is feedback or whistling that will not stop, if the shell is cracked, if a receiver wire is kinked or damaged, or if the aid gets wet.
Ear discomfort, itching, drainage, or a feeling of blockage is a medical question, not a cleaning question. That belongs with a doctor or an audiologist, and cotton swabs pushed into an ear canal are not the answer to any of it. Cleaning the device reduces wax buildup on the equipment. It does not treat anything happening in the ear itself.
The pattern is familiar from other small personal equipment. Dry tools, gentle handling, replace the consumables on schedule, and route the hard questions to a professional. The same care applies when you clean a digital thermometer or clean a retainer case and a mouthguard case.

FAQ
How often should you clean hearing aid domes?
Wipe the domes with a dry cloth and brush the sound opening daily, and inspect them closely once a week. Most people replace domes entirely every one to three months, sooner if wax production is heavy. Discoloration, stiffness, splitting, or debris that will not brush off all mean it is time.
Can you wash hearing aid domes with water?
It is not recommended. A dome that goes back on damp carries water straight into the receiver opening, and water is what damages hearing aids. Dry tools, a soft cloth, and the brush from your cleaning kit do the job. Replace a dome rather than trying to wash it clean.
How do you know when to change a hearing aid wax guard?
The usual signal is a sudden drop in volume, a muffled sound, or one aid going quiet while the other works normally. Change the guard before assuming the device needs repair. Many people replace guards on a set schedule, often monthly, and never wait for the symptom.
Can you clean a hearing aid wax guard?
No. A wax guard is a disposable filter designed to fill up and be replaced. There is no way to clean one, and poking at it pushes wax toward the receiver. Use the replacement tool that came with your aids, or ask your audiologist for one.
What should you never use to clean hearing aids?
Keep water, alcohol, disinfecting wipes, and cleaning sprays away from them entirely. Never use a hair dryer, oven, or radiator to dry an aid, since heat destroys the electronics. Never poke a pin, paper clip, or toothpick into a sound opening, because it can puncture the receiver.
What do you do if a hearing aid gets wet?
Remove any disposable battery, leave the battery door open, and place the aid in a drying container or electronic dehumidifier. Do not apply heat from a dryer, oven, or radiator. Contact your audiologist, since some moisture damage needs professional attention even when the aid seems to recover.
Does cleaning hearing aids help with ear wax problems?
Cleaning the device removes wax from the dome, guard, and shell so the aid works properly. It does nothing about wax inside the ear canal itself, and cotton swabs make that situation worse. Itching, drainage, blockage, or discomfort are questions for a doctor or audiologist.
