In extreme cases of stubborn shed or to treat dehydration I have soaked a snake for about 20 minutes and then I just wipe them down gently with a rough textured towel ... you just wrap it up in the towel and let it slither around inside ... when it's head pops out simply cover it up again ..
The skin all comes off nice and gently on the towel.
The easiest way I've found to ensure a perfect shed is to know your snake well .. as soon as they go into shed mode .. eyes glaze over / go blue and they fade in colour plus they disappear for a day or two.
I spray the viv well each day THEN as soon as the eyes clear and colour returns to normal you spray two or three times a day until you find the shedder skin four to seven days later ..
