that is rad! honestly... fill it slowly with an oxyclean solution, let it sit for a day, dump it out, refill it with hot water once or twice and dump it out and you should be good! only issue is... i'd fill it with something uncarbonated. because you wont know if it can handle the carbonation... so mead. apfle...howeveryouspellit. wine. etc.
cool find though!
