Best way to remove protective plastic from acrylic bath

[jamesmorris86]

Hi guys. I'm trying to remove the protective plastic from a new acrylic bath tub and it's proving rather difficult. So far I have tried white spirit and a sticker remover but it's not really working. The plastic is almost like cling film. Does anyone have any ideas?

It won't Peel off, it just comes off in tiny little shreds
