Hey guys,
I know this is a film question, but I figured I'd ask it anyway.

I'm wanting to try Polaroid 55 film -- the one that makes both a positive and a negative -- and I know you have to clear the negative in sodium sulfite. The question is, how many negatives can you put through the sulfite? I'm assuming you can reuse it to some degree, right?
Thanks in advance (if anybody replies at all, lol),
Sam
