Editorial policy

These are absolute rather than aspirational, and they are the reason several things you might expect to find here are missing.

• No fabricated testing claims. We have not used these products and no page implies otherwise.
• No invented specifications. Where a manufacturer does not publish a figure, the page says Not published.
• No invented prices. Prices come from a live data layer or they do not appear at all.
• No testimonials or reviews. This site has no customer reviews, so there is no testimonials section anywhere on it. An empty space is better than a fabricated quote.
• No invented credentials. The author bio claims nothing beyond what is true.
• No fake urgency. No countdowns, no stock scarcity, no price-rise warnings.
• No sponsored content. No brand has paid for placement or seen a page before publication.

1. 01You tell us — see contact. A specific figure and the page it is on is the most useful form.
2. 02We check it against the manufacturer's published data, which is the same source the page was built from.
3. 03If we were wrong, we fix it and update the page's review date.
4. 04Material corrections are noted on the page itself, not quietly edited away.
5. 05If the page stands, we explain why rather than ignoring it.

Every page carries its last-reviewed date at the bottom, and that date moves only when the page actually changed — not on every deploy.

• Prices refresh automatically and expire after 48 hours without a refresh.
• Product availability is checked with every price refresh. A product that stops resolving to a live listing gets replaced.
• Roundups are reviewed when the category moves — a significant new product, a discontinued pick, or a pattern of failure reports.
• Technique guides are reviewed annually, because the physics of washing a car does not change quickly.
• Any page gets reviewed immediately when a reader reports something wrong with it.

By editorial judgment of the published evidence, using a visible rubric. The metrics on each product card are the rubric, and they are shown so you can see what was weighted rather than being asked to trust a number.

Commission rate plays no part in ordering. Several pages here rank a cheaper product above a more expensive one, and the starter-kit guide's central advice is to not buy the most expensive thing. The full method is on how we pick.

• Specifications are cited to the manufacturer, with a link, on the product card itself.
• Pages carry a Sources section where they draw on standards bodies or technical documentation.
• Citation links are not affiliate links. They earn us nothing and they are there so you can check us.
• We do not cite other affiliate sites as evidence for anything.

Every page on this site is written and published under one byline, Mike M., on behalf of Iron Mako Media. There is no anonymous staff and no rotating freelancers, which means there is also nobody else to point at when something is wrong.
