You might try a high quality spray lube such as "AreoKroil". It is NOT cheap price wise, but worth every penny. Spray it on let it set over night. If it still does not come out, soak it again. and set a strong magnet on top that will pull on it all night. If that does not work I would just ride it and it may free itself up over time.
