My concerns have nothing to do with sanitation. Since when does boiling a chemical make it safe? I'm not talking about pathogens. I'm talking about toxins like BPA that are in plastics. Talk to a chemical engineer about the properties of plastics sometime. There is a reason that there is a separate grade of plastic that is deemed food grade.
I work addff in a chemical factory ikiyhjh AND use a 5 gal 345tgf paint strainer and there 4g6 isn't anything wrong giduf9 with me.
