First
of all, I have to be honest. The worst-case scenarios, such as a
hearing aid that's gone through the washing machine, are too far
gone. If your hearing aid has gone through the washing machine, it's
a goner. Don't even bother trying to revive a hearing aid that's
been through the washer.
If
the hearing aid has only been exposed to mild or moderate moisture,
such as rain or falling into a puddle, it might be possible to revive
it. The quicker you are able to revive it after exposure, the most
likely your aid will “survive.” For the record, I've done this
twice. One of the times I was successful, and the other time I
wasn't. It all depends on the amount of moisture and how quickly you
are able revive it.
Here's
how to revive a hearing aid:
Step
1: If the hearing aid will not turn on, disconnect
the hearing aid from the earmold tubing, remove the battery,
and open the battery pack. (Dispose of the battery.
Batteries can't withstand any moisture.)
Step
2: If a dehumidifier is handy, put the hearing aids in it
right away. If you don't have it on hand, put your hearing aid
in a container or ziploc with a bunch of rice. If you don't have
access to a dehumidifier or rice, set your hearing aid and earmold
out on a flat surface. Try turning it on again in a couple hours or
so. If you get sound, awesome! If you don't, move on to step 3.
Step
3: Turn a blowdryer on low speed and low heat and blow-dry the
hearing aid for a few minutes. If you're at work or out and
about, the hand dryers in the bathroom should suffice, but don't hold
it too close. (Do not blow-dry the mold, just the hearing aid.)
If your hearing aid has not been exposed to copious amounts of
moisture, it should revive by this point. If it doesn't, you can try
leaving it in the dehydrator overnight. If it's still dead in the
morning, it can't be revived.
If
you don't have a hearing aid dehumidifier or a blow-dryer, get both.
Everyone who uses hearing aids must own a blow-dryer, male or female.
Blow-dryers are relatively inexpensive and they can save your
hearing aids.
