I bought some CA unbond (remover) from my LHS & it works pretty darn good. It turns the CA all rubbery & you can just rub it off.
I haven't tried it on a canopy or monocote yet so you'll certainly want to test it on them before going to town.
I use it a lot on my foamy's to recover my horns & motor mounts after the plane goes to a better place.
I use a HobbyTown brand but here's one on Tower:
