Is this scale rot? Skin infection?

[Stewart_Reptiles]

I started cleaning it with an antiseptic and applying an antibiotic ointment 2x a day.

STOP NOW

This should only be done when warranted and this is not, whatever it is and scale rot shows as brownish scales simply keep your BP clean and dry, make sure the substrate is not damp. White BP will show every single scale scrape and defect.

By applying antibiotic twice a day what you are gonna do is loosen up the scales which will fall off, while antibiotic ointment is great in some instances it has to be used with caution and moderation since it is oil based.
