04 — THE METHODOLOGY
Clarity is
the whole point.
No false precision, no mystery AI answers. We explain published care mark meanings and make uncertainty visible.
Referenceable, not random.
International interpretations follow the publicly described ISO 3758:2023 symbol system. For U.S. markings we use the FTC-hosted ASTM chart and distinguish that legacy U.S. labeling convention from the latest ASTM D5489-25 edition. The reference systems do differ.
Instructions, not certification.
Custom illustrative diagrams help you recognize a mark. They are not an official reproduction of protected care-label artwork. This curated resource does not cover every historical or regional variant, and it cannot inspect your garment or its construction.
GINETEX states that its care symbols have trademark protections and use can require licensing, including for websites. Read GINETEX's licensing position ↗.

Source register reviewed 30 October 2026 · version 2.005 — BEFORE YOU WASH
Good questions.
Clear answers.
Does 30°C mean I have to wash at exactly 30°C?
In the ISO tub marks, the printed temperature is the maximum. A lower temperature can be suitable, but follow the specified cycle and full garment instructions. Lower temperatures may not clean as effectively.
Why are there two different symbol systems?
Many international care tags use ISO temperature numbers. The U.S. FTC-hosted ASTM chart includes temperature dots. Some ironing temperature thresholds differ too. The decoder keeps these references separate so it doesn't silently merge their rules.
Can I tumble dry when the tag doesn't show a dryer?
An absent symbol is not an automatic yes. Look for written instructions and consult the garment manufacturer if needed.
Will this identify the marks from a photo?
Not currently. You select what you can see. This avoids guessing from blurred or partly hidden printed symbols; the app does not claim camera recognition.
Can I use the guide instead of the sewn-in label?
No. It is an independent educational interpretation aid, not a substitute for the finished garment's instructions. Written manufacturer instructions have priority whenever they clarify or restrict a process.
