Assuming the glue can be reached by a liquid you can try liberly
wetting a section with Krud Kutter which I bought at home depot to
remove glue from vinal tile after ripping out a rug. took 24 hours of
soaking with a bit of water added now and again to keep floor wet.

I used it full strength and it did not harm wood basebord or vinal.
also no smell to speak of.
