For some reason Rollei omitted the two standard washing steps in C-41 processing. You should wash for 3:15 minutes after the bleach and again after the fixer. You can take the lid off the tank to wash after the bleach if it is easier to wash your film that way. By including these two wash steps, your image quality will improve. The first time I used this kit I did not wash because the instructions didn't include it, and my images were very yellow compared to the same image processed by a lab. After adding the wash steps, my film looked like the lab film.
