Water Displacement 40th formula (aka WD40) should be fine on the case

WD-40 will do a good job, but it's oily, attracts dust and pocket lint, and stains clothes. Contact cleaner evaporates and leaves no residue.

I have one for sale

How much?

That's how I explained it to my wife. The key just walked out on its own

I washed mine too I was all dirty and tried getting my clothes in the wash in hurry before I tracked dirt and grease all over the house and forgot about the key fob in my pocket. It went through the entire wash cycle. I found it when putting the clothes in the dryer. I took it apart blew it dry with compressed air and replaced the battery and has been working for months with 0 issues. I know there is rubber gasket material around the edge where it splits open and under the buttons that I'm sure helped the circuit from getting wrecked and was in my pocket not just floating in the washer getting knocked around

shoot me an offer

Got your electronic equipment wet? Quickly remove battery - don't try to shut off, just pull power. (iPhones and devices that cannot access battery, shut down using the least amount of buttons possible). Drown it in purified/distilled water for about an hour. Completely submerge it to the point no debris, residue, dirt, etc can be left on the device. Change the water and repeat if necessary. Take covers off and air dry for 30 minutes, then put in paper towel and into a zip-loc bag of rice to remove humidity. After 48-72 hours, put back together and use.

I've horrified friends with cell phones and remotes showing them going through full wash cycles, dropping in Lake Norman, and in a bathtub of bubble bath.
The thing is you need to get any corrosive elements and chemicals off the solder points as possible and and debris out of the device. Purified and distilled water is the fastest and safest way to do that.

Hopefully you never run into that situation, but I always have a gallon of distilled water in my pantry in the event the iPhone or either android gets wet.

I've heard from many sources (some were actually reliable) that it works, but never been brave enough to try it myself. :)

I only knew it worked after I started building a fish-tank pc and misread 'mineral-oil' as 'mineral-water'. I had already submerged my motherboard with ram, fans, processor, and whatnot into 11 gallons of water. Luckily, I never applied the power, but I pulled it all, 'dabbed it dry with a clean towel, and put into cardboard box and place a layer of paper over it, then poured in 5 bags of rice and taped it up. A week later I pulled it and inspected the boards, contacts, solder points, and grounding slots and all were clean. I called my father (electrical engineer) and he said that I need to dump them again this time in distilled water as mineral water could have iron and other elements that would ruin the pc over time, if not immediate. I must have asked "really?" 10-12 times while on the phone. So, I re-filled the tank with distilled water and dropped it all in, making certain to give it time to allow any residue to break off. Then repeated the drying process I did earlier. To this day, that 486 still runs as a storage hosting using Ubuntu.

I would also say, even after leaving some advice, don't take advice from forums if you feel uncomfortable with the method. I only posted because I trusted my father and actually have *saved* many devices this way, even though some of the devices would have probably been fine with just drying out (tv remotes, etc).

While I didn't do it myself, I did see an Apple //e that had been stolen and abandoned outside during a rain storm "revived" using distilled water. Lots of mud on and in it. Tech disassembled the computer, and rinsed everything down with water and some soft brushes. Didn't submerge it. He then put the boards in a file rack. I didn't get to see the rest of this, but according to the tech, he set up a small fan to blow on them, and left them for three days. Put it back together and it worked (except for the floppy drive and the video would flicker every now and then)! I can't swear that the distilled water did the magic - maybe tap water or nothing at all would have worked - put there ya go.
