Tri-Flow. It's a lightweight oil + teflon, and doesn't evaporate like WD-40. It's marketed primarily to the cycling community, but I tend to use it where most people would use WD-40 (fixing squeaky hinges, loosening bolts, etc.)
Your link is mixing up the two molecules by calling PFAS "The Teflon chemical". "Teflon", the non-stick final product, is PTFE with a very strong fluorine chemical bond and no chance of reacting with the human body at normal temperatures (That's why nothing manages to stick to it, basically). PFAS were used by DuPont in the manufacture of Teflon (and recklessly dumped into the environment).
PFAS are an ecological disaster; Teflon itself is not a concern.
