will start to harden and might turn yellow. This will affect

Hearing aid body
Use a soft dry cloth or tissue to wipe down the body of your
hearing aid gently. This is an electronic device. Don't use any
liquids (water, solvents or cleaning agents) on the body of your
hearing aid. Should you do so, your hearing aids will break.
Note: Make sure to handle your hearing aid over a soft
surface during the cleaning process in order to prevent
damage to the hearing aid, should you drop it.
Caution:
• If you do not follow the list above you may damage your
hearing device and accessories during cleaning.
• Do not immerse your hearing aids in water or liquid,
even when cleaning. Follow the recommended cleaning
guidelines to clean your hearing aid.
• Do not bend the slim tube back and forth to remove it.
