the paper towel trick is to ensure a gentle heat transfer and to avoid the risk
of squeezing the traces.
you don't have to 'rub' the paper off, you must 'peel' it off. the rubbing is
with a brush to remove the rest of coating from between traces and in holes
(will prevent etching!). just leave it enough time in the water and lift the
borders slightly to let the water slip in (under) and do its work...
5 minutes may not be enough, 10 to 12 is more likely if you have thick
waterproof paper!
the epson photo paper (not extra glossy) usually swims off after some 4-5
minutes... ah, and drop the 'hot' board into the water, don't touch it, use
whatever you have by hand to push it!
