I note that this and the Nulon brand that I’ve used list TETRAchloroethylene rather than trichloroethylene as a constituent. I wonder if that’s any safer. The Wikipedia page[0] says it has been described as a possible "neurotoxicant, liver and kidney toxicant, and reproductive and developmental toxicant ... a 'potential occupational carcinogen'"
