Tips of care hearing aid:
1. when you remove your hearing aids every time, wipe them off with a clean, dry cloth or tissue. Do not use alcohol swabs or cleaning solvents as these may damage the material your hearing aid is made of.
2. Apply any hair products – such as sprays or gels — and face creams before you put your hearing aids in for the day. If you wash your face with a cleanser at night, take your hearing aids out before you do. These materials can clog the microphone and may also be damaging to the plastic material.
3. Keep your hearing aids free of earwax/ cerumen. This yellow substance can clog the microphone and receiver, blocking the sound to your ear. Large amounts of earwax can create a crackling, static or feedback sound.
