Spraying is an easy option
I spray their vivs whenever I'm doing water changes and whenever I think about it but when mine go into shed I spray the viv EVERY day then as soon as their eyes clear and they get their colour back I start spraying a few times each day ... You'll probably find the messy , rolled up lump of skin UNDER his hide afterwards ) .
Note they get their colour back and the eyes clear a few days BEFORE the skin actually comes off .
