Hey guys,
2 days ago (~46 hours) my arduino get wet because of a hole in my bottle. (It was just water, no juice or something... And not really wet, just like you would hold it under the shower for about 1-2 seconds)
Can I plug it in again without fearing it to get destroyed? It's not wet anymore... It's just a question to be sure.
And if I shouldn't plug it in because it could be destroyed what am I supposed to do to "fix" it?
If it's really dry it should be ok. Pure water (no salts or other minerals) should not hurt it at all. But to be sure it is really dry, maybe it would be wise to put it in an oven set to about 110 degrees for half an hour or so first. Or if you live in an area with a very hot sun this time of year, just set it out in the sun for a few hours.
I presume @pegwatcher means 110 degrees fahrenheit which is much cooler than 110 degrees centigrade.
I can't quickly find temperature limits for Arduinos but 110C seems too high to me.
...R
Yes, fahrenheit. Sorry, I am a yankee. We generally use fahrenheit and forget that some here use centigrade.
Oops, and there was me, thinking 110K was just going to solidify the water

At low temperatures, most home ovens are not accurate for temperature.
I would suggest using a hair blow drier to insure the board is dry.
Even better would be to get some denatured alcohol and wash the board off with that. It will absorb any water present and then evaporate cleanly and completely.
I've rescued a lot of cell phones dropped in water by washing them out with alcohol, then just letting them air dry overnight.
It should be obvious, but WARNING! Alcohol is extremely flammable. Don't use near flames or smoke while using it.
I like that alcohol idea. Will remember that one.
or, forget about heat and alcohol altogether! Put it in a sealed container with a cup of rice or some of those dessicant packets that come in new shoes and stuff. Leave it overnight and you should be golden!
Forget about alcohol?
Are you crazy?

Uh huh... so bathing it in isopropyl or using a heat gun not good enough?
I'll stick to tried and tested methods, not hoping rice will dry it out...
AWOL - Yes, yes I am. But sanity is over rated.
Seriously though the rice thing really works, any kind of desiccant will absorb the moisture, you could even stick it in a bag af cat litter if you don't mind the smell. Also there is a product I encountered recently, it is a little disk you put in the drawer of your tool box to prevent surface rust, I forget the name of it but that also works by absorbing moisture
cjdephi - Its not a hope, it is a proven method, and if you have doubts about rice the desiccant gel is scientifically formulated to absorb moisture.

Yes the rice will along with silica (those little balls in a bag? ).... but it's also slow and in some cases ineffective because water/moisture gets trapped under/inside of components, if this water is not removed and current is applied the tracks with moisture begin to corrode ...
Don't
As the saying goes there is more then one way to skin a cat. If you seal your device in an air tight container or bag and are patient you can rest assured that the trapped moisture will be taken care of.
I am not going to argue about it, I simply shared my way of dealing with wet electronics. If you don't like it don't do.
