Editorial policy

• Commission rate never affects ranking. Where a cheaper or better-stocked option earns us less, it still goes first.
• No brand pays for placement, for a review, or for a position in a roundup. There is no paid-inclusion tier and no sponsored post on this site.
• No brand sees a page before publication. Not for fact-checking, not for approval, not for a quote.
• We will recommend a product that earns us nothing when it is the right answer — including, on several pages here, buying nothing at all or using something you already own.
• Links are disclosed on the page, above the first call to action, not only in the footer.

A product that fails the second test is not accused of anything. It simply cannot be written about honestly, because the most important fact about it is undisclosed.

1. It is currently sold.
2. Its material composition is published in enough detail to say what the user-contact surface is.
3. Every safety claim about it can be labeled as third-party certified, a manufacturer claim, or independently tested by a named party.
4. It is the best answer to a specific question, not a generically acceptable product.
5. Its trade-off can be stated in one sentence.

• It is discontinued or no longer buyable in the form described.
• A reformulation changes the material or the certification position.
• A certification lapses or turns out not to cover what we said it covered.
• Independent testing published by a credible third party contradicts the manufacturer's claim.
• We find that we got it wrong.

These are absolute, and they are the reason several things you might expect to find on a site like this are missing.

No invented reviews, testimonials, ratings or review counts. This site has no verified customer review data, so it has no testimonials section and no star ratings anywhere — including in its structured data. A clean page with none beats a page with fabricated ones.

No invented prices. Prices render only from a live price source. There is no live price feed for this site yet, so every price slot reads "check price on Amazon" and links to the live listing. A stale number is worse than no number.

No testing claims. We have no testing program, so the words tested, hands-on, field-tested, lab-tested and in our kitchen do not appear as claims about our own work anywhere on this site. Where a third party has tested something we name them and link them.

No invented credentials. The author's background is stated on the about page at exactly the scope that is true, and no further.

Email contact@glassandcotton.com with the page and the correction. If we are wrong, we change the page, and the last-reviewed date on it moves. Where a correction changes a recommendation rather than a detail, we say what changed on the page itself rather than quietly editing it.

Dead links count as defects here and are fixed on the same route.

Commercial pages are re-checked when a product is discontinued, reformulated or a cited source moves. Reference pages are re-checked when a standard changes — the retirement of NSF P473 into NSF/ANSI 53 and 58 in June 2021 is the example we cite most, because articles still quoting it are quoting a standard that no longer exists.

Every page carries its last-reviewed date and author. If the date is old, weight the page accordingly; that is what it is there for.

Where community consensus contradicts a recommendation on this site, we report that rather than suppressing it, with the thread linked and the disagreement stated plainly. Several roundups here say in as many words that forum opinion disagrees with a pick, and why we kept it anyway.

We do not fabricate, paraphrase into a quote, or attribute a view to a named user.
