The complete laundry symbols chart (explained)

· ~8 min read · Last verified: October 2026 · Meanings checked against GINETEX (owner of the standard)

Every care label in the ISO 3758 system uses the same five shapes in the same order: a tub (washing), a triangle (bleaching), a square (drying), an iron (ironing) and a circle (professional care). Once you know the five shapes, the modifiers do all the work: numbers give a maximum temperature, dots give a heat level, bars mean "be gentler", and a cross means "don't".

Key takeaways

  • Number in the tub = maximum water temperature in °C — never exceed it.
  • One bar = milder cycle (reduced mechanical action); two bars = very mild (woollens).
  • Tumble-dry dots: 1 dot ≈ 60 °C, 2 dots ≈ 80 °C. Iron dots: 1/2/3 = low/medium/high.
  • A cross over any symbol is an absolute prohibition — not a suggestion.
  • This chart covers ISO 3758 (used on EU/UK/Asian labels); US labels use the same shapes with the ASTM dot system.

Washing symbols — the tub

The tub's number is the maximum water temperature, which must not be exceeded (GINETEX's documented wording). Bars underneath soften the cycle. Common numbers are 30, 40, 60, 70 and 95 °C.

SymbolNameWhat it means
Machine wash 30 °CWash at up to 30 °C on a normal cycle ("fine wash").
Wash 30 °C, mildOne bar = gentler cycle with reduced mechanical action.
Machine wash 40 °CWash at up to 40 °C — the everyday "coloured wash".
Wash 40 °C, mildGentler cycle at up to 40 °C ("easy care" on many machines).
Wash 40 °C, very mildTwo bars = very mild cycle, e.g. a wool programme.
Machine wash 60 °CWash at up to 60 °C — towels, bedding, sturdy cottons.
Machine wash 95 °CBoil wash for sturdy whites.
Hand wash onlyHand wash at a maximum of 40 °C (the 2023 revision also defines an ambient ~20–30 °C hand wash). No machine, no wringing.
Do not washThe item must not be washed at all — usually it goes for professional care.

Bleaching symbols — the triangle

SymbolNameWhat it means
Any bleach allowedBoth chlorine and oxygen bleach are tolerated.
Oxygen bleach onlyTwo oblique lines: non-chlorine (oxygen) bleach only.
Do not bleachNo bleaching agents of any kind, including bleach-laced detergents.

Tumble-drying symbols — circle in a square

SymbolNameWhat it means
Tumble dry, lowOne dot = reduced temperature, about 60 °C.
Tumble dry, normalTwo dots = normal temperature, about 80 °C.
Do not tumble dryNo tumble drying at any heat — shrinkage and damage risk.

On US (ASTM) labels you may also see three dots (high heat) or a filled circle (no heat). Full guide: Can I tumble dry this?

Natural-drying symbols — the plain square

Added to ISO 3758 in 2012, the plain square tells you how to dry without a dryer: vertical lines mean hanging, horizontal lines mean lying flat, and doubled lines mean "dripping wet, no spin". A diagonal line in the corner means "in the shade".

SymbolNameWhat it means
Line dryHang on a line or hanger after spinning.
Drip line dryHang dripping wet — no spin cycle.
Dry flatLay flat to dry — knits and sweaters keep their shape.
Drip dry flatLay flat while dripping wet, without spinning.
Dry in shadeThe corner diagonal modifies any dry symbol: keep out of direct sun.

Ironing symbols — the iron

SymbolNameWhat it means
Iron, lowMax sole-plate temperature 110–120 °C (references differ; see the dots article). Nylon, acetate, acrylic.
Iron, mediumMax 150–160 °C. Wool, silk, polyester, viscose.
Iron, highMax 200–210 °C. Cotton and linen.
Do not ironIroning may cause irreversible changes — usually to prints or finishes.

Professional care symbols — the circle

SymbolNameWhat it means
Dry clean, PTetrachloroethene (perchloroethylene) or hydrocarbons — any solvent except trichloroethylene.
Dry clean P, mildBar = restricted process: reduced mechanical action, limited moisture, lower drying temperature.
Dry clean, FHydrocarbons (petroleum solvents) only.
Dry clean, AAny solvent — a legacy marking, mostly on older labels.
Wet clean, WProfessional wet cleaning — water-based, done by a professional.
Wet clean, mildMilder professional wet cleaning for sensitive textiles (double bar = very mild).
Do not dry cleanNo solvent cleaning — and avoid solvent-based stain removers.

How to read any label in five seconds

  1. Find the five shapes left to right: tub, triangle, square, iron, circle.
  2. Read the modifiers: number = max °C, dot = heat level, bar = gentler, cross = never.
  3. Obey the crosses absolutely; treat everything else as a maximum, not a target.

Delicate-wash mesh bags + wool detergent

If your labels are full of one-bar and two-bar symbols, a mesh laundry bag and a wool-safe detergent make any gentle cycle gentler still.
