My Dad recently got his extractor back from family that was storing it for him for many many years (20+). It has some rust on the bottom inside (I think around the base of the "spinning component" and also around the top of the basket that you place the frames in) and he's asking if anyone has any ideas on A: how to get it off and B: is there anything he can coat it with (paint, etc.) after he gets as much rust off as possible. Obviously we don't want to use anything that could "compromise" the honey. Thank you!
