Hearing aids are tiny, high-tech devices that are worn on and, in the ear, — a place where wax, debris and humidity congregate. Following are a few simple care and maintenance tips that will help ensure your hearing aids are always performing their best.

• Wash your hands before handling.
• Always handle your hearing aids with care and, when changing batteries or cleaning them, do so in a clean, well-lit environment.
• Store your hearing aids in a safe, dry place away from children and pets.
• Turn off your hearing aids when you are not using them.
• Periodically clean the battery contacts and remove any visible earwax or debris with a soft, clean cloth.
• Change filters or wax guards regularly to remove wax and dirt that may degrade sound quality.
• Don’t wear your hearing aids in the shower, sauna, while swimming or while using a hair dryer or hair spray.
• 8. Schedule routine checkups with your hearing professional for thorough, expert cleanings.

It’s not uncommon for hearing aids to require some degree of professional service, which is why hearing aids are typically sold with warranties and repair coverage. Cleaning your hearing aids regularly can drastically reduce the number of repairs required during the life of your hearing aids and help keep sound quality high.
