how long to dry?

By Jaqui ·
when some dimbulb manages to knock an entire cup of coffee INTO the case, getting every component inside covered in the hot liquid, how long to let it dry off before firing it back up?

[ amazingly enough, the powered up system did NOT fry at the time it happened. ]

Untill they find this numbnuts replacement?

The thing here is to make sure that you not only get the liquid, but also any sugra that might have been in it.

With it unplugged I'd wipe out as much of it as I could. Pull the cards and make sure that nothing got into the slots as well.

Cofee and soda are the worst.

right, unfortunately

it was me and my own system.

I put the coffee down and went to sit down, knocking the coffee over and watched the tin cup fall into the open case.

no sugar, just coffee and cream.

metal coffee cup.. hot coffee, open case, powered up system, and nothing fried.

that is just amazing.

Besides just wiping it dry....

... I would use denatured alcohol and a Q-Tip to clean every square inch of every component, including down in the slots.

As Bart said, coffee and soda are the worst kind of spills. Remember, in the old days, those two liquids were used to clean rubber stamps. They're NOT good for computer components, especially when they're allowed to dry.

what?

ammonia based glass cleaner not a good idea?

I think taking it down to components and scrubbing it under runner cold water got all the coffee off.

I don't know.....

by ThumbsUp2 In reply to what?

... according to the news this morning, there's traces of drugs in the drinking water. Maybe you need to use bottled water?

Whatever you use, be sure to disassemble all of the components and let a fan **** on them for a few hours.

Distilled Water

by TheChas In reply to Besides just wiping it dr ...

Alcohol is not necessarily the best cleaner for a water based spill.

Flushing the system with distilled water and then allowing it to air dry would be my choice. Most circuit board manufactures are using some form of water based cleaning these days anyway.

As to how long to let it dry, I would say a minimum of 4 hours. Longer if the humidity in the office is high or the temperature is low.

Most of the circuit board materials are at least slightly hygroscopic, and will absorb some of the water. You want to give them enough time to fully dry out before applying power. There are also small spaces between the components and the circuit board. These can hold water droplets for longer than you might think.

The circuit board cleaning systems usually use some form of air knife to force the cleaning rinse out from under parts.

I have some non-conductive

by Dumphrey In reply to Untill they find this num ...

parts cleaner I use in these situations, and more commonly on keyboards. It cleans up and dries out much like wd40 does for cars and locks.

Dry time is 24 to 48 hours depending on current conditions.

Not just dry out time

by Tig2 In reply to how long to dry?

Cleaning will have to occur.

I have immersed pagers in isopropyl alcohol for 30
minutes and then let dry for a few hours after the pager
was soaked by another liquid (Can we all say "knocked
into the toilet"?). That was effective.

In a computer I have used isopropyl to clean
motherboards but the times that I have done that were to
de-gunk from random dirt, not clean up after a spill.

By theory, the isopropyl displaces the other liquid but
dries very quickly and does not leave residue.

I would give it a minimum of 24 hours and every prayer
you can think of.

Good luck!
