Scale rot treatment, need help

Hi, everybody
I'm pretty sure my corn snake (large 4-5 yr old male) has scalerot. I know what caused it : with his last shed I probably misted to much water in his viv. He had problem with a couple of previous shed (big chuck of skin instead of a long nice one) so I wanted to raise the humidity to help him out. It was a bad idea and won't do it again. Fortunately, my other snake (wich i did the same thing to her) didn't get it (she is in an other viv). I included pictures to show you how it looks. The first one is probably the best to show how it looks.

So I wanted to know how to treat scale rot.

What I've done so far :
In his viv : removed all of the aspen, replaced it with paper towel, removed all the other stuff (hide, branch, leaves) and put a shoe box as a hide

Treatment : Applied peroxide mixed 50/50 with water followed by some polysporin (contains polymyxin B (as sulfate) and bacitracin zinc). I could not find the Neosporin other people talks about, but i think it's the same active ingredients.

Right now I treat my snake twice a day, but plan to reduce the frequency next week.

So my questions are

1. Am I doing the right thing ?
2. How do you apply the peroxide and cream ? (I use cosmetic pads that rub on him for the peroxide and my hand for the polysporin)
3. How long should I keep treating him ?
4. How frequently should I treat him ?
5. Is there anything else I should do ?
6. How long before it's all cured ?

Thank you a lot

Probably the best one


These two are a little blurry, but show a bit what is looks like

Forgot to add :
He was abnormally pretty active in the past few weeks and isn't eating for about a month and a half.

I thought it might be because of the female in the other room, but maybe it's just because it was itching/hurting him and wanted to scratch himself to relieved the itching. Right now, after 2 day of treatment, he is more calm.

Update:
My snake is much more calm right now, I hope it's because it's itching less.

He is also entering the blue, so i'll post an update after the shed. I hope it's gonna be better.

Bump.

I'm sorry I'm no help Bibz, don't know what to do for that. I was hoping to learn a little from reading your solution.

There are plenty of knowedgeable people here, someone help!

He shed ! It went very well.

His scales looks much much better. There is almost no more brown, there are some spots that i'm not sure, so i'll continue to treat him, but less frequently, maybe every 2 days.

Here is an updated picture. I can still see some broken scales, but they seem to be healing good and I can't see all the brown that was there before.

Weird thing: he seems to have much more orange on his belly than before (not shown in picture), maybe I just haven't noticed it before.

Huh. Interesting; I've never seen scalerot before.

To help with sheds I like placing a "damp hide" in their enclosure, not humidifying the whole enclosure. The damp hide is a plastic shoebox with damp sphagnum moss. That way the snake can choose when it wants humidity; they usually do camp out in the damp hide box before shedding.
