As others have said, as long as it is sealed, it should be fine. If you have some issues, first try GENTLY cleaning the contacts with an eraser as they can get a thin film on them that affects conductivity.
If it did go through the wash, at least you know all you photos should be "clean" (sorry for the horrible pun)
Never an eraser or anything abrasive on the contacts as the gold plating is only microns thick. Use isopropyl alcohol on a Q-tip and dry completely before inserting it into a device.
