Laundry Care Symbol Decoder

Care labels use a small, standardized set of symbols instead of written instructions so a single garment tag works across languages without translation. The system in wide use today traces back to GINETEX, the International Association for Textile Care Labelling, founded in France in 1963 to standardize what had been a mess of inconsistent, manufacturer-specific labeling across Europe; that symbol set was later folded into the ISO 3758 international standard. The United States uses a related but not identical system, codified in ASTM D5489, which is why a US-made garment's tags sometimes look slightly different from an imported one even though they're communicating the same five categories of instruction: washing, bleaching, drying, ironing, and dry cleaning.

The five symbol families

**The tub** (a basin shape) covers washing. A plain tub means machine wash is fine; a tub with one wavy line underneath signals permanent press (a gentler machine cycle that reduces wrinkling); two lines mean gentle or delicate cycle; a hand resting in the tub means hand-wash only — no machine, of any cycle; and a tub with an X through it means don't wash at all, full stop, which usually pairs with a dry-clean-only instruction elsewhere on the same tag.

**The triangle** covers bleach, and it's the symbol most worth reading carefully before treating a stain, since this is exactly where a stain-removal method can go wrong. An empty outlined triangle means any bleach, including chlorine, is fine. A triangle with two diagonal lines inside means non-chlorine bleach only — oxygen-based bleach is fine, chlorine bleach is not, because chlorine will damage the fiber or shift the dye. A triangle with an X through it means no bleach of any kind, which shows up on wool, silk, and most spandex-blend activewear, since chlorine bleach breaks down protein fibers and degrades spandex elasticity even in small amounts.

**The square** covers drying, usually with a circle inside it to distinguish tumble drying from air drying. A circle with no dots inside the square means tumble dry at normal heat is fine; one dot means low heat only; a square with just a vertical line (no circle) means line dry / hang to dry; a square with a horizontal line means dry flat, which matters for knits that stretch out of shape if hung wet; and a circled square with an X means no tumble drying at all.

**The iron** is a literal small iron shape, with dots indicating heat level — one dot for low heat (typically synthetics), two for medium (wool, polyester blends), three for high (cotton, linen). An iron with an X means don't iron the item at all, which usually pairs with heat-sensitive trims, sequins, or certain synthetic coatings that will melt or glaze under direct heat.

**The circle** covers professional dry cleaning. A circle with a letter inside (usually A or P) tells a professional cleaner which class of solvent is safe for that fabric — information aimed at the cleaner, not at a home user. A plain circle with an X means the item should not be dry cleaned at all.

Why this matters before you treat a stain

A stain-removal method is only as good as what the garment is actually allowed to tolerate. Enzyme presoaks and oxygen-based treatments are safe under the non-chlorine-bleach symbol; a hot-water soak that would otherwise be the right call for a protein stain is ruled out the moment the wash symbol shows a low-temperature or hand-wash-only instruction, since heat and protein stains together are what makes them set permanently. Checking the label before starting is a five-second step that avoids turning a stain into a second, self-inflicted problem — see the matched removal method for a specific stain and surface pair on the Stain Solver.

When symbols conflict with general stain-removal advice

The care label always wins. If a general guide on this site recommends an oxygen-based bleach soak but the garment's triangle has an X through it, the label takes priority — some fabric blends and trims are more sensitive than the general fiber-type guidance accounts for, and the manufacturer has tested that specific fabric.
