Temperature, detergent, bleach, drying, storage: what the published evidence supports, and how much of the standard laundry advice turns out to have nothing behind it.
Almost every bamboo sheet is rayon, and the FTC has spent fifteen years enforcing that point. What the process does, and what the antibacterial and eco claims are worth.
Three words that look like points on one scale are actually three different kinds of claim: a variety, an origin, and a licensed trademark. Only one has a verification program.
One interlaces every yarn; the other floats yarns across the surface. Everything people notice about the two follows from that, including the claim the evidence does not settle.
Thread count is not a quality score, and it is not meaningless either. What the number counts, how plied yarns inflate it, and the single letter the FTC has written about it.
Nine things decide what a sheet is like to sleep on and how long it lasts. Most of the words printed on the package describe none of them, and some are not regulated at all.
Enameled cast iron is glass fused to iron, and nearly every care rule follows from that. What the manufacturers actually say, including the three places the popular advice has it backwards.
A nonstick box carries more claims than almost anything else in a kitchen store, and almost none of them is regulated. What each term actually means, and which ones tell you nothing at all.
Food sticking to stainless is not a defect. Protein bonds directly to bare metal and the bond gets stronger as the pan heats up, which means most of the popular advice is right for the wrong reason.
Seasoning is a real chemical film, not leftover grease. But the polymer story everyone repeats is the leading hypothesis rather than settled fact, and the most-cited advice traces back to one blog post from 2010.
Cast iron, carbon steel, stainless, nonstick and enamel behave differently because of two measurable properties: how fast a metal moves heat, and how much heat it holds. Understand those two things and choosing cookware stops being a matter of opinion.
