I have been using MEK to help me remove wood glue. Does
anyone use anything else that doesn't cause cancer.

There's always water when the glue is wet (although nobody's proved
that water DOESN'T cause cancer...), or a chisel once the glue has
just started to dry. If you have a lot of squeeze-out, you should
probably use less glue in the first place.

Or are you talking about removing glue that's already cured from
inside joints? For dissembly/restoration, I've heard that either
moist heat or vinegar can help.

There's also a product called waxilit that can be spread on bare wood
near your glue joint, so squeeze-out won't stick to the wood. The wax
can then be removed with alcohol, and it won't interfere with
finishing (or so they advertise - I haven't tried it).

Good luck,
Andy
