Stick it in a card reader and try. Dollars to doughnuts, it will read just fine. If not, put it in a lingery bag and run it through a wash cycle, sans detergent. I've had two go through with no damage, after drying a week or so (as a precaution after going through the dryer too). That will get the salt and crud out of the contacts. You have nothing to lose.
I'm not sure I would use this card again on an important trip or job.
