[quote=vabeachcouple33]Here's an even better dessicant. You're gonna need to do some homemade chemistry and be a little careful, but this is the best you'll get.
You can make your own anhydrous magnesium sulfate from Epsom salt. I'll give the chemistry explanation at the bottom.
Put some Epsom salt in a glass oven safe dish in an oven at 475 F. Let it sit there for at least 2 hours. It will lose a little over half its weight. It will change from sparkling crystals to white powder. Shut the oven off and let it cool down with the door closed.
When it's cool enough to touch the dish with your bare hands, remove the dish and transfer the now anhydrous magnesium sulfate to a jar with a tight fitting lid (like a mason jar).
To use it, put the befouled electronic device or other thing you want dessicated in a lidded container (plastic takeout containers are great) about twice it's footprint. On the other side, carefully spoon some of the magnesium sulfate beside it. Be careful not to get it ON your electronics.
Close the lid and give it a couple of hours. Putting it somewhere warm (80- will speed it up.

Epsom salt is magnesium sulfate heptahydrate, meaning it has 7 water molecules for each magnesium sulfate ion pair. 1 "mole" (a chemistry unit for the quantity of atoms in something) weighs 246 g. Once those waters are all driven off, a mole of anhydrous magnesium sulfate weighs just 120 g. So if you want to know if you've succeeded, measure the weight before and after. 100% success means a 51% weight loss. Don't worry if you don't quite get there - it'll still work.
Fun Fact: Epsom salt is more than 50% water :)[/quote]God you’re so hot when you get all scientific.
Love the tip. Saving this to memos.
