Remove A White Film on Carboy
Steve Auer — Coos Bay, Oregon asks,
I have a large 12-gallon (45-L) carboy (see photo below). There’s a film on the inside of the glass. I’ve cleaned with One Step and have tried to scrub inside with a bottle brush many times. I Cannot remove film. The carboy currently has wine in it, but you can see its size. Any help would be appreciated.
