Scale Rot

[Archer]

There is a single dark (grey-orange) scale on Hershel's back, I noticed it yesterday while holding him and I'm really worried.
I've replaced his substrate (Eco-Earth) with paper towels (so that I can clean his Viv everyday until he gets better), but could someone inform me on how to treat early scale rot? I've heard that an iodine solution bath is good, but I don't have that right now and won't until tomorrow. I'll try to upload some photos.
