How to read care labels

What the FTC Care Labeling Rule requires, and what every washtub, triangle, square, iron, and circle symbol means.

Why the label is there

US care labels exist because of the FTC Care Labeling Rule, issued in 1971. Manufacturers must tag clothing with at least one safe cleaning method — either washing instructions or dry-cleaning instructions — and must warn against any listed-method step (washing, bleaching, drying, ironing, or dry cleaning) that could harm the garment or other items washed with it. [1]

Only one safe method is required, and the label does not have to warn about methods it doesn't list. A label that says "washable" is not telling you the garment can be dry-cleaned, and vice versa. The listed method works as a care warranty: if you follow it and the garment is damaged, you can return it. [1]

Since July 1997, symbols may replace words. The minimum laundering label is four symbols in a fixed order — washing, bleaching, drying, ironing — while dry-cleaning instructions are a single symbol. The symbols described below are North American; garments made elsewhere may use different systems. [1]

The symbols pictured below are redrawn as simplified line art from the chart in the University of Tennessee Extension publication cited on this page, which reproduces the FTC-accepted set (ASTM D5489-96c, Fig. 1). The chart also defines added dry-cleaning marks for short cycle, reduced moisture, low heat and no steam finishing; see the source PDF for those exact shapes.

The washtub: washing

A plain washtub means machine wash on a normal cycle. One bar under the tub means permanent press; two bars mean a delicate or gentle cycle. A hand in the tub means hand wash. A crossed-out tub means do not wash, and a crossed-out twisted symbol means do not wring. [1]

Dots inside the tub set the maximum water temperature: one dot is 30°C (65–85°F), two dots 40°C (105°F), three dots 50°C (120°F), four dots 60°C (140°F), five dots 70°C (160°F), and six dots 95°C (200°F). [1]

The triangle: bleach

An open, empty triangle means any bleach may be used when needed. A triangle with diagonal lines means only non-chlorine bleach when needed. A filled-in triangle with an X over it means do not bleach. [1]

Symbol meanings from the cited chart. [1]

The square: drying

A circle inside a square means tumble dry — plain for normal, one bar for permanent press, two bars for delicate/gentle. Dots inside the drum circle set the heat: no dot means any heat, three dots high, two dots medium, one dot low, and a filled circle means no heat (air only). [1]

Squares without the drum circle give non-tumble instructions: an envelope-fold line means line dry or hang to dry, vertical lines mean drip dry, a horizontal line means dry flat, and diagonal lines in the corner mean dry in the shade. A crossed-out symbol means do not tumble dry or do not dry that way. [1]

The iron

Dots on the iron symbol set the maximum sole-plate temperature: one dot is 110°C (230°F, low), two dots 150°C (300°F, medium), three dots 200°C (390°F, high). A crossed-out iron means do not iron; crossed-out steam lines mean no steam. [1]

Symbol meanings from the cited chart. [1]

The circle: dry cleaning

A plain circle means dry clean, normal cycle. A letter inside narrows the solvent: A means any solvent, P means any solvent except trichloroethylene, F means petroleum solvent only. Additional marks can call for a short cycle, reduced moisture, low heat, or no steam finishing. A crossed-out circle means do not dry clean. [1]

Beyond the symbols

The label also tells you the fiber content, which drives how a stain should be treated — see the materials pages for fiber-by-fiber constraints. Example labels on real garments read like "machine wash warm, non-chlorine bleach, tumble dry low, do not iron" for cotton, or carry "do not bleach" for silk and acrylic. [2]

Upholstered furniture uses a different system: letter cleanability codes (W for water-based cleaners, S for solvent only, W/S for either, X for vacuum only) on a tag rather than apparel care symbols. Our only fetched source for these codes is a furniture retailer's explainer, so treat that page as weakly sourced. [3]

Safety

Always follow care and product labels. Never mix cleaning products — especially anything containing chlorine bleach with ammonia or acids. If swallowed or splashed in eyes, contact Poison Control (US: 1-800-222-1222 or poison.org).
