Last, week, I accidentally bought a used Jobo reel from Latvia. When it arrived, I figured I'd better clean it as who knows what process(es) the previous owner was running on that reel. I soaked it for 48 hours in a strong solution of dish soap, then scrubbed each reel half down aggressively with a stiff-bristled scrub brush. During the scrubbing a LOT of dark gray foam flew off and splattered everywhere, so the reel was obviously dirty. Then I soaked the reel for 24 hours in a citric acid solution (10g/L) and scrubbed it with dish soap a second time. On the second scrubbing, the soap suds stayed bright white.

Am I done or should I also soak it for 24 hours in a sodium sulfite solution? I've used a soap and an acid, so I'm wondering if I should soak it in a base as well just to make sure I've got it as clean as possible.

What do you guys think?
