Once you’ve cleaned your hearing aid, dry everything well before putting it back together. Moisture can cause damage and malfunctions, and can shorten the service life of your hearing aid. If your hearing aid does get wet, never dry it using a hairdryer, heater, microwave, or similar device, as high heat can soften and distort the plastic parts and damage the internal technology.
For gentle drying, use a specially designed air blower, drying box, or drying pouch. These are available from your clinician. In general, we recommend storing your hearing aid in a drying box overnight, which dries the hearing aid electrically and ensures improved cleaning thanks to UV light. Ensure that the battery compartment is open and that the hearing aid battery
has been removed.
