We all know water and electricity don’t mix, but many of us forget this includes
As my son found out this week to his cost (well, my cost obviously!). The story starts a while back when he came home from school soaked to the skin (I warned him about the weather forecast, but he is 14 so
Later on I took the key fob apart to swap out the battery,
Oh, so it needs a little more than a new battery then...
I brushed off the worst of the muck and (rather optimistically), popped the circuit board into the ultrasonic cleaner for a
The moral of this tale is that you must act quickly
Try this next time something of yours gets wet…
- Take off any covers and remove the battery ASAP and I mean ASAP, before you stop to say ‘oh
- Counterintuitively, rinsing everything at this point with distilled water might help here (it’s the muck or soluble salts in water which do the damage). Definitely rinse if
sea water is involved.
- If you have one, a small ultrasonic cleaner could help at this stage.
- Getting the water out:
- Consider a sharp downward flick (holding on
VERY tightly of course) to throw out the majorityof the water.
- If comfortable, take out any screws and open up the item for better access and to increase
air flowaround the insides.
- Warm air is good, so consider using a hair dryer to blow out and warm up the insides.
- You can also use compressed air (if you have access to it) to blow out any water droplets (be careful though around screens etc.).
- Then pop the whole thing somewhere
quitewarm. Not crazy hot like on top of the wood stove, but above a radiator or in an airing cupboard for example. 30 degrees or sois great…
- If you have it, surround the item with sachets of silica gel, those little moisture absorbing packets (Some say use rice, but studies show it’s
prettyineffective, paper towels are better). A bag works well here. But to be honest, warm air works okay.
- A minimum of 24 hours later (preferably longer), pop the battery back in and tentatively press the power button…
If you’re lucky, you might have cleaned away any salts and be just in time to stop any corrosion forming. Once the item is fully dry and operational again for a week or so (and if you’re
Obviously, your success with the above
Good luck, you’ll need it.
