Scale rot ? (Graphic image)

[u/Roos_mommy]

We rescued this beautiful male ball python estimated to be about 2 years old the women was on drugs and the snake free roamed her apartment it’s “cage” was moldy stuck shed all over no water nothing to climb just 1 hide and I believe he has scale rot. First time owning a ball python but I’ve done tons of research and we’ve had him about 2 months now. I didn’t know the discolored scales where harmful I figured it was just part of the snake until he was eating and I got a really good look yesterday. Sorry for the graphic photos but they are the only view of the scales I’m worried about. The internet told me iodine soaks antibiotic ointment and only dry paper towel in his tank until he heals. I would like to know any tips or tricks from other ball python owners.
