Wax is great, but it isn’t as likely to stick to smooth surfaces for long periods, or if things get hot or abrasive. It’s good on cloth, covering a dish you put in the fridge — but not sure how it would work with burger wrappers or cups of hot coffee, that are where most PFAS are used. I’d love to check if, in a straw, it would be perceptible. Metal straws remain the simplest solution.
