In case the hearing aid does get wet, it should be dismantled and put in a dryer. There are many kinds of driers and most of the time the hospital provides these with the hearing aid. The most common model is a drying jar, where the device is placed with a moisture absorbing dehydrating capsule. Those who use a cochlear implant are often given an electrical dryer, which is recommended for regular use since it absorbs moisture and therefore extends the hearing aid’s working life. It’s also worthwhile to use the dryer daily when traveling in humid countries. Then you should use rechargeable batteries rather than batteries, due to the waterproofing.
