Hey all, I've just finished removing most of Hector's first shed with me, it was the worst I've ever experienced?

I had to soak him in a bucket for 20min then run it off with a towel, eye caps all stuck...
I was aware he was gonna shed because he went slightly blue and very very wrinkly, horizontal wrinkles... I've not had a snake go wrinkly before. I was spraying daily bumping it up too 70% and it would drop to 50 again by the next morning.
I'm actually considering a fogger if this becomes a regular occurrence.
He still has a tiny bit on his tail tip and bottom jaw I will get tomorrow as he was getting agitated. I can't seem to get the humidity above 70 even with two vents covered, maybe it's the che and Brian barcyk substrate?
Any tips on kalatoa retic sheds? I've read they rarely do a full shed but people must get round it?
