We are restretching some of our newman frames that have had polyken tape on them for 18+ months now and I'm having a hard time getting all the old polyken tape residue off them.
we were trying to use franmar 'icky-sticky-unstuck' which sucks in my opinion
xenon xenzu pac worked decently...
but neither seem to work as well as oven cleaner, which obviously is very toxic and not labeled for this use in the shop.
anybody have any other suggestions of what works 'best'?
