A little off subject but not much. Many years ago when Pledge with lemon oil
first came out and Deft (the prefered poly in my area at the time) was just
beginning to be used you could not mix them.

Deft is most famous for brushing lacquer. Lacquer is redissolved by
solvent. Varnishes, including polyurethane varnishes, go through a
chemical reaction when they cure and are not able to be redissolved by
their original solvent.

Could the product that original Pledge was removing actually have been
Deft lacquer and not a polyurethane varnish at all, hence the confusion
and problems?
