Find out what chemical pesticide they used and ask for the MSDS (Material
Safety Data Sheet). It is required by law to be provided to employees and
consumers.

Most likely if your floors were waxed then the chemical dissolved the wax
coating. If the gloss was a finish on the tiles when purchased then the
tiles were damaged. Going to harsher cleaning may make it worse. You'll
need some kind of floor coating - whether wax or something else. If you
know the manufacturer of the linoleum check with them and see what they
recommend.

Hopefully none of this pesticide got on your collection.

Cheers!
