Every Care Label Symbol, Decoded
The five care symbols and their variants, who owns them, what US law actually requires, and why the crossed-out drying symbol is the one that costs you money.

Care symbols look like a language you were expected to be born knowing. They are a system of five drawings, some dots and some lines, and it takes about two minutes to learn. Here is the whole grammar, plus the legal backstory that explains why your imported sweater’s symbols differ from your American t-shirt’s.
The five symbols
Read the label left to right. The order never changes: wash, bleach, dry, iron, professional care.
- Washtub — washing. Dots give temperature: one dot means cold, up to 30°C; two means warm, around 40°C; three means hot. Bars under the tub mean a gentler machine cycle. A hand in the tub means hand wash.
- Triangle — bleaching. An empty triangle permits any bleach; a triangle with diagonal lines restricts you to non-chlorine bleach; a crossed-out triangle forbids bleach entirely.
- Square — drying. A circle inside means tumble dry, with dots setting heat: one low, two medium. Lines inside mean dry flat or drip dry; a crossed-out square forbids the machine.
- Iron — ironing. One to three dots inside set the temperature from low to hot. Crossed out, it means do not iron.
- Circle — professional textile care. Letters matter: P allows perchloroethylene, F allows milder hydrocarbon solvents only, W marks professional wet cleaning.
Who owns the symbols
The five drawings are property. GINETEX, the international association for textile care labeling based in Paris, holds the five base symbols as registered trademarks, and its system is embodied in the ISO 3758 standard used across Europe, the UK and much of Asia — manufacturers there are expected to license the marks. The United States never adopted that set. Federal guidance recognizes only the similar-but-not-identical ASTM D5489 symbols, and even those are voluntary: the FTC’s Care Labeling Rule (16 CFR Part 423), in force since 1971, requires care instructions in words, or ASTM symbols in place of words. A European label washed up on American shores is legal shorthand, not compliance. In the EU, care labeling itself is voluntary — only fiber content is mandated.
What the US rule actually demands
The rule asks for one reliable care method covering the item’s useful life: a washing or dry-cleaning instruction, plus warnings for anything a reasonable person might do that would ruin the garment — the “do not bleach”, “do not iron” lines. If a garment survives neither washing nor dry cleaning, the label must say so outright. The instructions must be on a permanent label that stays attached and legible for the garment’s life. This is also where the commonest mistake hides.
The crossed-out symbol that costs the most
The most expensive symbol on any label is a crossed-out square with a circle in it — no tumble drying. Heat-shrinkage is quick and permanent: one hot cycle can take a wool blend or structured cotton down a full size, and no cleaner undoes it. Second place goes to the crossed-out triangle on anything with elastane or wool, where chlorine bleach eats the fiber. If you keep one habit, make it this: before the first wash, scan the label for crossed symbols and honor them. The rest of the system is optimization; the crosses are warnings.
Caring for what you own is the cheapest form of the discipline that a capsule wardrobe audit rewards — fewer, better pieces stay better only if the label survives the laundry. The same read-the-fine-print instinct applies off the clothing rack: jewelry keeps its own rules about what water and perfume do to a finish.
FAQ
- Are care symbols legally required in the US?
- No. The FTC's Care Labeling Rule requires care instructions on most apparel, and those instructions may be written in words or given with the ASTM D5489 symbol set. No American rule mandates symbols, and symbols alone only satisfy the rule if they are the ASTM version, not the European set.
- Can I ignore a care label and wash anyway?
- You can, and cold-water hand washing is gentler than most labels assume, but the crossed-out symbols mark the specific failures the maker's testing flagged. Ignoring a crossed-out tumble-dry symbol is the fastest way to shrink a garment; ignoring a crossed-out iron symbol is how coatings and synthetics melt.
- What is the difference between dry cleaning symbols P and F?
- P means the garment tolerates perchloroethylene, the standard dry-cleaning solvent, or hydrocarbon solvents. F means hydrocarbon solvents only — a milder process for fabrics that perc would damage, such as some coated or bonded materials. A crossed-out circle means do not dry clean at all.
