Is there any way to verify that without getting a Lab to do an analysis? I'm not sure if I can trust stuff labelled BPA-Free from Amazon for example.
Buy from a reputable seller for anything important, instead of amazon.
Or, there are apparently at-home testing chemicals that look simple to use. I haven't done it myself though.
Yeah I would assume that given how easy it is to start a new Amazon seller account and how impossible it is for some random seller in China to face legal repercussions from the US, the likelihood of finding an “_____-free” item to actually be made of whatever the cheapest and most readily available formulation is. (Including the _____), is pretty high.
Even if they are, that doesn't mean they're safer
