Submergable USB Key
Earlier today I copied some pictures onto a USB key to take to CostCo for processing some enlargements. Copied the files onto the key, took them in and used one of the store machines to load and crop images – and stuffed the USB key carelessly into the pocket of my board shorts.
Went about a few errands through town and then headed to the beach to check on surf and wind which is huge and marginal respectably. The forecast was calling for surf of sets with 30+ foot faces, although it didn’t quite make it that big at Kanaha (or even Hookipa for that matter). Anyway after hanging around for a while and endless wind deliberations a few of us decided to go out regardless of the light conditions. So off I go into the washing machine with the USB key happily coming along for the ride. Wash, Tumble, rinse, repeat… I took it on the head a few times today and had a few long swims after my gear.
Next as if that wasn’t enough I decided to go to Yoga and sweat in a 105 degree room with 90% humidity for a an hour and half. USB key is still happily along for the ride…
So tonight – sufficiently beat up by the day – I get home sit down at the computer and… remember the USB key. Oh shit. I forgot to take it out before going rinse cycling and pig sweating… after a quick hustle I retrieved the USB key and it had a few pieces of seaweed stuck to it and a little rust mark…

It couldn’t possibly still be working after all that, could it?
So… I plugged it in and – nothing. Ah, too bad. But wait – nope it’s just the lock key that was set by all the rustling. Switch the key and… can you belive it the damn thing still works. Amazing. After having been completely submerged in water for probably 30 minutes + throughout the day, absorbing stinking acrid sweat the thing actually manages to still work…
I wonder if I should try that with the camera next <g>…

Sit it in your car on the dashboard in the sun with the windows closed - that's how I got my cell phone working after I jumped in the pool with it in my pocket.

Any way I would have to say that I have washed and dried mine probable around 50 times. I have to say the first time it happened I was worried but to my surprise it still worked. Since then I just pop in the wash for the occasional cleaning (just kidding).

The reason that water (and most liquids) kills electronic devices is that water is a conductor of electricity and if you power up the device whilst it's wet the water will create a short circuit and potentially destroy the device. Even when it's dried out there's still a risk of destroying the device as any residue left from the liquid could still be conductive and therefore create a short circuit.
This is why I'd suggest cleaning with isopropylene which is cheaply available from most electronic parts suppliers.
I hope that helps anyone who has dropped or spilled liquids on and electronic device?

similar happened to me. Washing machine + tumble dryer. It still works and it's clean!
