IANAL, but I believe the generic U.S. wire fraud law would cover the examples I mentioned. As to why it doesn't cover advertising a "cleaning product claiming it can remove all stain", I am not sure but my best guess is that it might not fully satisfy the "intent to defraud" or "material fact" elements.
