Retired food safety specialist working in fresh food processing. Quat is part of normal hygiene, but "leftovers" are not left over for the next day. At home during quarantine, it's nice to be able to check the strength of the spray guns on a daily basis and not reshuffle. At home I use Steramine tablets in 1/2 gallon H2O for a 400ppm solution.
