It seems to defy everything I try!

Acetone - never buy hammerite thinners now just get big cheap bulk
bottles of acetone ( which incidentally seems particularly good at
tackling jobs where other solvents fail.
In an emergency your wife's nail polish remover will do the job too as
it is mostly acetone too.

( I have attempted to get her to use pure acetone on her nails as it
is much cheaper than the stuff she buys but she won't...)
