If people will be eating off that floor, or conducting surgical procedures on that floor, then yes: You're supposed to send samples to a private lab, and you would be negligent if you were buying soapy water without checking.
If an underling at my restaurant replaced all dish-washing liquid and bleach solutions with a series of small metal figurines taped to the dishwasher and the prep tables, and told me "It cleans the surfaces galvanically", I'm not going to say "Brilliant!", I'm going to say "Brilliant, now prove it before it's allowed near my kitchen."
More seriously though, at some point you need to stop. Capitalism is a fun game for adults, and entrepreneurship is a prestigious sport, but when people start dying because someone sold them something built with the purpose of earning him money by making other people die, one should stop hoping for the market forces to bankrupt him and just jail the murderous SOB directly.
