Why is this comment misinformed? In a video tour of his home lab, Sam Zeloof shows us his acid-storage cabinet and mentions that he gets HF from over-the-counter Whink-brand "Rust Stain Remover"[1].
Since this product is commonly available at hardware stores across the United States, why should comments related to it "be deleted because it is so dangerous"?
I agree that HF can be extremely dangerous, but in this case it's not clear that Sam is working with or advocating use of dangerous concentrations or chemcial forumulations of fluorine-based acids. Maybe I missed a post where he does discuss using more dangerous concentrations or compounds?
