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!

Hi All,We recently had a small pest issue in one of our collections storerooms and the facilities department put some kind of pesticide on the floor which left patches of cloudy white residue on the linoleum. After consulting a housekeeping manual we attempted to clean the floor with a mild solution of vinegar and water, which cleared up the white discoloration, but mattepatches were still visible after the floor had dried, on an otherwise glossy linoleum floor. I am unsure if these patchy areas are just a physical change or stain to the surface of the tiles or if this indicates the floor needs to be more thoroughly cleaned/requires a stronger cleanser? I am hoping some of you may be able to advise. Thanks in advance.Erica
