Laundry Signs Meaning: How to Read Every Care Tag on Your Clothes

You flipped to the care tag on a new blouse and found a row of symbols that look like ancient hieroglyphics. No words, just icons. You guessed, washed it on hot, and now the blouse is two sizes smaller. Those symbols aren’t random. They’re an international standard that tells you exactly how to clean each garment, and understanding them is the difference between clothes that last years and clothes that last three washes.

Laundry signs are standardized symbols printed on clothing care labels that indicate the appropriate washing method, water temperature, bleach type, drying method, and ironing settings. They were developed by the International Organization for Standardization (ISO) and are used on clothing worldwide.

To understand laundry signs meaning, identify the symbol shape first: a washtub means washing, a square means drying, a triangle means bleaching, an iron means ironing, and a circle means dry cleaning. Dots inside indicate temperature. Lines under the washtub indicate cycle type. A cross through any symbol means don’t do it.

Washing Signs and Their Meaning

The washtub is the first and most important symbol. It tells you how to wash the garment.

Washtub with no lines: Normal cycle. Standard wash with moderate agitation. Use any temperature shown by dots or numbers inside the tub.

Washtub with one line under it: Permanent press cycle. Moderate agitation with lower spin speed. Good for synthetics and wrinkle-prone fabrics.

Washtub with two lines under it: Gentle or delicate cycle. Minimal agitation and low spin. Good for lace, lingerie, and lightweight knits.

Hand in the washtub: Hand wash only. Don’t machine wash. Use cold water and gentle soap. Don’t wring or twist.

Crossed-out washtub: Do not wash. The garment is dry clean only.

Numbers in the washtub (30, 40, 60): Maximum water temperature in Celsius. Don’t exceed this temperature.

Dots in the washtub:

• One dot: 30C (cold water)
• Two dots: 40C (warm water)
• Three dots: 50C (hot water)
• Four dots: 60C (very hot)
• Five dots: 95C (boiling)

Drying Signs and Their Meaning

The square symbol tells you how to dry the garment.

Square with a circle inside: Tumble dry allowed. The circle represents the dryer.

Square with circle and one dot: Tumble dry on low heat. Good for most clothes.

Square with circle and two dots: Tumble dry on medium heat. Good for cotton and sturdy fabrics.

Square with circle and three dots: Tumble dry on high heat. Good for towels and bedding.

Square with circle and two lines under: Tumble dry on delicate cycle. Low heat and minimal tumbling.

Crossed-out square with circle: Do not tumble dry. Air dry only. This applies to silk, wool, lace, and anything with elastic.

Square with a curved line at top: Line dry. Hang on a clothesline.

Square with a horizontal line: Flat dry. Lay the garment flat on a surface. Good for sweaters and knits that stretch when hung.

Square with vertical lines: Drip dry. Hang dripping wet without wringing.

Square with diagonal lines in corner: Dry in the shade. Keep out of direct sunlight, which can fade colors.

Bleaching Signs and Their Meaning

The triangle symbol tells you what bleach is safe.

Empty triangle: Any bleach allowed. Both chlorine and oxygen bleach are safe.

Triangle with two diagonal lines: Oxygen bleach only. No chlorine bleach. This is common on colored fabrics.

Triangle with letters CL: Chlorine bleach only. No oxygen bleach.

Crossed-out triangle: Do not bleach. No bleach of any kind. Common on dyed fabrics.

Ironing Signs and Their Meaning

The iron symbol tells you the safe ironing temperature.

Iron with one dot: Low heat (110C). For silk, synthetics, and delicate fabrics.

Iron with two dots: Medium heat (150C). For wool and polyester blends.

Iron with three dots: High heat (200C). For cotton and linen.

Iron with steam lines: Steam ironing is allowed.

Crossed-out iron: Do not iron. The garment can’t be ironed at any temperature.

Crossed-out steam (lines with cross): Don’t use steam. Dry iron only.

Dry Cleaning Signs and Their Meaning

The circle symbol indicates dry cleaning instructions.

Empty circle: Dry clean only. Take to a professional cleaner.

Circle with letter A: Dry clean with any solvent.

Circle with letter P: Dry clean with any solvent except trichloroethylene. This is the most common dry clean symbol.

Circle with letter F: Dry clean with petroleum solvent only.
