I find that MEK works OK, but it does soften (dissolve) hypalon, so you need to work just on the glue spots as much as possible. If you do see the hypalon starting to soften (surface gets a bit gummy), take a break and allow the solvent to evaporate before resuming work.
Toluene does a good job, but is rather dangerous to use, as it affects the human body in weird ways.
I can't get Bostik products easily here in the US (left coast), so have to use alternatives.
