Make sure it is White Spirit that you get... is used as a thinner for enamel paints and a hardware worker will tell you that Turps and White Spirit are the same... they are 2 completely different things when it comes to glue removal as Turps wont touch it
The solvents I usually try when removing adhesive are White Spirits, Metho, acetone and Turps, and it depends on the composition of the adhesive as to which works and which doesn't.
