To get stubborn skin or bits off you can wrap the snake up in a wet , rough textured bath towel and let it slither around in it .. when it’s head pops out simply cover it up with the excess towel and continue.. any dead skin will normally come off onto the towel without hurting the snake at all .
I don’t recommend pulling bits off by hand .. I tried it many years ago with a Woma python ... I must have hurt him because he sure hurt ME !!
