The Clean Groove guides are research-based, not hands-on product tests, unless a guide says otherwise.
Sources we use
- Manufacturer specifications: sizes, ratings, materials and sizing charts from the maker's own pages and manuals.
- Retailer listings: current versions and what is actually sold.
- Expert sources: published guidance from recognized organizations and professionals, linked in the guide.
What we don't do
- We don't invent test results, star ratings or prices. Prices change, so the button shows the live price on Amazon.
- We don't use manufacturer or Amazon photos; our pictures are illustrations (see image credits).
- Commissions never decide what we recommend.
