Regular maintenance of Ilfochrome processors is a must, there are many components that need regular checking especially in the Bleach bath. I have attached a sample of why regular maintenance is a MUST. in the picture attached I show a normal Bolt for a bleach rack on the left before it has been installed into a processor. The 2 screws on the right are from 6 months exposure to ilfochrome bleach. note how the bleach has dissolved the screws. If such corrosion isn't seen to this can cause huge problems to the machine. parts need constant replacement. I think this is a good example as to how strong the chemistry in this process is.
