How to Read a Wash-Care Label: Every Symbol Explained
Every care label is really the same five icons repeated in different combinations: a wash tub, a triangle, a square, a circle, and an iron. Once you know what each shape family means, a label you've never seen before still tells you exactly what to do — no memorising a chart of hundreds of variations required.
The wash tub: how to launder it
A tub filled with wavy lines is the washing instruction, and everything about it is coded. The number inside (or written next to it) is the maximum water temperature in Celsius — a tub with “40” means 40°C or cooler, never hotter. A hand resting inside the tub means hand-wash only: no machine, ever. One line underneath the tub means use a permanent-press or synthetic cycle; two lines mean a gentle or delicate cycle. A tub with an X through it means don't wash it at all — dry clean or spot-clean only.
The triangle: bleach
A plain triangle means bleach is fine. Two diagonal lines inside the triangle mean only non-chlorine, oxygen-based bleach is safe — the kind sold as a colour-safe or all-fabric bleach. A triangle with an X through it means no bleach of any kind, which usually shows up on coloured synthetics and anything with elastane, since chlorine bleach degrades that stretch fibre over repeated washes.
The square: drying
A square represents drying, and what's inside it tells you the method. A circle inside the square means tumble drying is fine, and dots inside that circle grade the heat — one dot for low heat, two for medium, three for high. A square with a single horizontal line means dry flat, which matters enormously for knits that would otherwise stretch out of shape hanging wet. A square with a curved line across the top means hang to dry, and one with diagonal lines in the corner means dry in the shade, protecting colour from direct sun. A square with an X through it means don't tumble dry at all, even if nothing else on the label restricts drying.
The circle: dry cleaning
A plain circle means the garment can be dry cleaned, and a letter inside it (usually P or F) tells a professional cleaner which solvent is safe to use — not something you'll act on at home, but a real instruction to whoever's machine the garment ends up in. A circle with an X through it means never dry clean it, which shows up on some plastics, sequins, and trims that solvents would damage.
The iron: heat while pressing
An iron shape with dots inside grades the maximum safe ironing heat exactly like the tumble-dry circle does: one dot for a low, synthetic-safe setting, two for medium (typically fine for wool and polyester blends), three for a high, cotton-and-linen setting. An iron with an X through it means don't iron it at all, which is common on anything with a printed design, sequins, or heat-sensitive synthetic fibres that can melt or glaze under direct heat.
Reading them together
A full care label is just these five icons in a row, and the useful trick is to let the most restrictive icon set the ceiling for the whole load. A shirt labelled for a 40°C wash, no bleach, low tumble heat, and low iron heat should be sorted with other low-heat items, not with the cotton towels that can handle 60°C and a hot iron — even if they're going in the same coloured pile. When a label is faded past reading or has been cut out, our Wash Temperature & Care Guide gives a sensible fallback based on the fabric alone.
