I haven't done reversal processing on B&W film for several years. I always used Kodak's system cleaner as my bleach since after reading the label & checking the MSDS it seemed exactly the same as a normal acid/dichromate bleach. It worked great...and I didn't have to mix up my own chemicals and worry as much about spilling/dropping nasty chemicals on myself. But now I can't get the same cleaner. Actually buying a reversal kit would work....but it was always so convenient to just run out to the store and buy the System Cleaner & use my regular developers, etc .......besides, it's just more fun to mix stuff up myself. Has anyone tried the new non-toxic tank/tray cleaners as a reversal bleach? I read online that Edwal's cleaner might make the silver soluble in a sodium sulfite solution. Anybody know about this?
