I`d keep the misting up dude, you don`t want her drying out or it could make things worse. I`m a little concerned about direct heat to that aswell. Can you arrange another method of heating? It might well not be an issue at all but if we put our preventative heads on for a moment, direct heat could potentially dry it out or otherwise irritate it. I can`t recommend proper cleaning AND disinfecting enough. Iodine is very good stuff for keeping things like this clean

I think infection and drying out are the main concerns here. You really don`t want that getting dry and flakey at all. Keep your misting up, once a day but a decent "rainfall" Keep it disinfected and I think you`ll be just fine

Well obviously YOU will, but your snake will too lol
