Mild Scale Rot: Advice Please!!

[Maks]

I found around 4-5 of my snakes scales having a very light brown colouration and one with some of the scale already ebbing away. I have read that it is good to soak the snake in a betadine solution bath (along with ointment) and I do intend to do so as I have already bought the materials. Now, here's my concern, the snake is currently in his 'in-blue' or opaque stage in shedding. I'm worried, should I start the betadine baths now or, should I wait for him to finish his shed? I don't want to damage any of the new skin but I also don't want to let the rot fester. I'm pretty new to this so I'd love any and all help I can get.
