Santa brought me some new film processing gear for Christmas so today I developed my first negative in a few decades. Much to my surprise it actually came out OK but when I put the negs through the scanner they showed a lot of dust/fluff. I guess I should have given all the gear a good wash before I used it but I didn't. So can I wash the fluff off the negs? If so what do I use, water, rinse-aid, fairy liquid ?
