A hearing aid can be a large investment

They can make the difference in how easily to adapt to your workplace, home or community.  Understanding how to care for your hearing aids is key to protecting your investment.  Here's a few tips:

Don't expose hearing aids to extreme heat or moisture.

As ane example, hearing aids should not be left inside a parked car in the sun, and moisture, (e.g. steam baths, showers or heavy rain). Note: that they must never be dried in microwave ovens or other ovens. 

  • avoid heat,
  • avoid humidity
  • and avoid chemicals.

Wipe the batteries if moisture is present as it may affect their performance. Using an anti-humidity kit can help to avoid these problems and may even extend the life of the hearing aid. Read the following advice, and please consult your hearing care professional for further advice.

Damage caused by wax

Your ear canal produces ear wax that may clog up the ear piece. Ear wax is one of the main causes of problems in ITE (in-the-ear) and RITE (receiver-in-the-ear) hearing aids. Most ITE and RITE hearing aids come with a filter or other device to prevent wax from entering the instrument.

Use the wax protection system provided with your hearing aids and the tools that came with them to clean away any accumulated wax each day. Consult your hearing care professional about the specific wax protection system in your hearing aids and how it can be replaced.

Moisture and dampness

Dampness and condensation can damage the circuitry in your hearing aids. Remove your hearing aids before swimming, showering or going out into heavy rain and don’t leave them in the bathroom. Dry any perspiration inside and around your ears regularly.

Open the battery door fully to allow air to circulate whenever you are not using your hearing aids, especially at night or for longer periods of time, and consider using a special drying kit. Your hearing care professional can provide advice on the best drying kit for your hearing aids.

Rough Handling

When handling your hearing aids, it is a good idea to keep them over a soft surface to avoid damage if you drop them. Keep your hearing aids in their presentation case or in a drying kit when you are not using them.


Protect your hearing aids from direct sunlight and do not leave them near heaters or in your car. Never put your hearing aids in the microwave or oven to dry them out.

Hairspray and makeup

Direct contact with chemicals in e.g. cosmetics, hairspray, perfume, aftershave lotion, suntan lotion and insect repellent can damage the hearing aid. Always remove the hearing aid before applying such products and allow time for the product to dry before refittingthe hearing aid. If lotion is used, be sure to wipe hands dry before putting on the hearing aid.

Keep hearing aids away from pets and children

Keep your hearing aids, their parts and batteries out of the reach of children and pets. Dogs can be irritated by the whistling sound from hearing aids and have been known to chew them. Hearing aid batteries can be dangerous if they are swallowed by children or pets. Contact your doctor or vet if a battery or hearing aid is accidentally swallowed.
