Methodology
How we pick
Every page here is research-based, and this is what that actually means — including the parts other sites leave out.
The one-line version
We have not used these products. Every pick is built from the manufacturer's published specifications, cited on the page, plus the consistent patterns across verified-purchase reports — and every page says so at the top rather than in the small print.
That is an unusual thing to lead with, and it is deliberate. Phase 0 research for this site found a wedding venue ranking for “best dual action polishers” while claiming eighty hours of testing, and a general-interest site whose nav covers Gaming, History and Celebrities ranking first for a beginner polisher term with a hands-on claim from a games writer. Both claims are unverifiable. Ours is the opposite kind of claim: everything we assert can be checked against the source we cite.
How products get onto this site
- Candidates come from the category research, not from what pays best. The question is which products a buyer in this category is actually choosing between.
- Each one is resolved through Amazon's catalog API to a real, currently-sold listing.
- The returned title is checked against the brand and model tokens we asked for. If the search returns a different product, it does not go on the site — we do not guess an ASIN.
- Products that cannot be verified are dropped entirely, and a comparable product that does verify takes the slot. Eight products were dropped this way when this site was built.
- The write-up is then built from the manufacturer's published figures and the owner-report patterns.
How prices work
Every price on this site is pulled from Amazon by an automated refresh and written into a data file. Nothing is typed in by hand, and no product type on this site even has a field where a price could be authored.
- Prices carry the date they were checked, shown next to every one.
- After 48 hours without a refresh they expire. The number disappears and the button falls back to “Check price at Amazon”.
- That is the failure mode by design: silence rather than a stale claim. If the refresh ever stops, the prices vanish instead of quietly going wrong.
- Amazon's price at the moment you buy is the one that applies. Ours is a snapshot, and we say so.
What the scores mean
Every product carries a score out of ten across four to six category-specific metrics, plus an overall. Those metrics are the rubric, and they are visible on the page so you can see what we weighted.
| What the score is | What it is not |
|---|---|
| Our editorial judgment of the published evidence | A measurement |
| Weighted toward what matters for a home detailer | A universal ranking |
| Comparable within a category | Comparable across categories |
| Visible on the page | Emitted as structured data |
That last row matters. The scores appear on the page as editorial content and are never emitted as Review or AggregateRating markup, because marking an editorial score up as a review rating of a product we have not used would contradict the label at the top of the same page.
The evidence labels
Every product carries one of two labels, and at launch no product on this site carries a third:
- Spec-verified — assessed from the manufacturer's published figures, cited on the page. We have not had this one in our hands.
- Owner reports — assessed from the pattern across verified-purchase reports and enthusiast forums, with the failure modes named.
- There is no hands-on tier. We do not have a documented product inventory, so claiming one for any product would be a fabrication. If that changes, the label will change with it and the page will say when and what.
Where specifications are missing
A surprising number of manufacturers in this category do not publish basic figures — a polisher's throw, a bottle's volume, a dressing's durability. Where that happens our spec tables say Not published rather than carrying an estimate.
A blank is more useful than a confident guess, and there are more invented numbers circulating in detailing than in most categories. If you see a figure on this site, it came from a manufacturer source we have linked.
What would change a pick
- A manufacturer publishing a figure we had marked Not published.
- A consistent, documented failure pattern emerging in owner reports.
- A product being discontinued or no longer resolving to a live listing.
- A reader showing us we got something wrong, which is the fastest route of all.
- Not: a change in commission rate. Nothing on this site is ordered by what pays.
The conflicts we have, stated plainly
We earn an Amazon commission on purchases made through our links. That gives us an interest in you buying something, which is a real conflict and worth naming.
What it does not give us is an interest in you buying any *particular* thing, because the commission is a percentage of whatever you buy. The practical effect is that recommending the cheaper product costs us money and costs us nothing else — which is why several pages here recommend the cheap option, and why the starter-kit guide's main advice is not to buy a polisher yet.
Questions people actually ask
- Have you tested these products?
- No, and every page says so at the top. Our picks are built from published manufacturer specifications, cited on the page, plus the patterns across verified-purchase reports. There is no hands-on evidence tier on this site because we have no documented product inventory.
- Where do the prices come from?
- An automated refresh pulls them from Amazon and writes them into a data file. They carry the date they were checked and they expire after 48 hours, after which the button falls back to Check price rather than showing a stale number.
- Do you get paid to recommend products?
- We earn an Amazon commission on purchases made through our links, at no extra cost to you. Nothing is ordered by commission rate, and because the commission is a percentage of whatever you buy, recommending the cheaper product costs us money and nothing else.
- Why do some specifications say Not published?
- Because the manufacturer does not publish that figure. A blank is more useful than a confident guess, and this category has more invented numbers circulating than most. Every figure you do see traces to a manufacturer source we have linked.
