The care label is the single most reliable guide to keeping a garment intact. It is set by the maker, who knows the fibre blend, the dye and the construction. Before applying any general advice — including the notes on this site — read the label, because it always takes priority.

The five symbol families

Most care symbols fall into five groups, usually shown left to right in the same order. Recognising the base shape tells you the category before you read the detail.

Base shapeMeaningWhat the detail adds
WashtubWashingDots or numbers indicate temperature; a hand means hand-wash; a bar suggests a gentler cycle.
TriangleBleachingA crossed-out triangle means do not bleach; lines can indicate non-chlorine bleach only.
SquareDryingA circle inside means tumble dry; dots show heat level; a crossed symbol means do not tumble dry.
IronIroningDots indicate the maximum temperature; a crossed symbol means do not iron.
CircleProfessional careLetters indicate the solvent a cleaner should use; a crossed circle means do not dry-clean.

A crossed-out symbol always means “do not”

An X through any symbol is a prohibition. This is the most important shortcut: even if you cannot read the rest of the label, a crossed-out washtub, triangle, square, iron or circle tells you to avoid that treatment entirely. Misreading one of these is the most common cause of avoidable damage.

Read fibre content too

The label's fibre breakdown is as useful as the symbols. Wool, silk and many blends behave very differently in heat and agitation than cotton, so the percentages tell you how cautious to be even before you reach the wash instructions.

Labelling in Canada

In Canada, textile articles are generally required to carry a label stating fibre content and the dealer's identity under federal labelling rules. Care instructions are commonly provided using the widely recognised symbol system. Because exact requirements can change, the authoritative source is the federal guidance rather than memory; the reference below links to it directly.

Build a short personal routine

  1. Sort by the washtub symbol so like temperatures wash together.
  2. Separate anything marked hand-wash, dry-clean, or do-not-wash.
  3. Check the drying symbol before using a machine; many knits should dry flat.
  4. Keep the label intact until you have washed the item successfully at least once.

For how this fits into storing and rotating clothes through the year, see the note on seasonal clothing rotation, and for choosing durable pieces in the first place, the capsule wardrobe guide.
