just got a NGP off the classifieds and i literally cant get the previous owners blacknmild juice out of the tank. i mean i got all of the actual juice out, and rinsed the tank with water about 10 times. then i filled with banana cream pie. all i can taste is black n mild, and zero flavor of banana cream pie, and to make things even better, my orion tank cracked yesterday and i just got all my new juice today. so basically im extremely frustrated.
