throw the hot board into a cold (warm) water bowl

paper should not be 'rubbed' off, it must 'peel' gently or even float off by
itself. may take more than 5 minutes...
if you have to rub --> wrong paper!!
it's ok to brush out some residues between tight tracks and holes.

are you using an iron? hot enough?
beware of the steam holes, they play dirty tricks!
do you use a paper towel 'buffer' between the iron and the TT paper back?, up
to 4 ply can be very useful.
