Laundry Symbols Guide: What Every Care Label Symbol Means

Every piece of clothing comes with a care label covered in small laundry symbols — and most of us have no idea what they mean. These symbols are standardized internationally under ISO 3758 and tell you exactly how to wash, dry, bleach, iron, and professionally clean each garment without damaging it.

This guide decodes every common clothing care label symbol so you can protect your clothes and get them properly clean, whether you're doing laundry at home or at a laundromat near you.

How to Read Laundry Care Labels

Laundry care labels use five basic symbol categories, each represented by a distinct shape:

• Washtub (bucket shape) — Washing instructions
• Triangle — Bleaching instructions
• Square — Drying instructions
• Iron — Ironing instructions
• Circle — Professional cleaning (dry cleaning)

Within each category, additional marks modify the meaning: dots indicate temperature levels, lines indicate gentleness, and an X through any symbol means "do not" do that action.

Washing Symbols Explained

The washtub symbol (a bucket of water) tells you how to wash the garment. The number inside or dots inside indicate the maximum water temperature. Lines underneath indicate how gentle the cycle should be.

When you see a hand wash symbol on your care label, wash the garment in a basin of lukewarm water with mild detergent. Gently agitate, rinse, and press out excess water without wringing. For more detail on washing different fabrics, see our fabric care guide.

Bleaching Symbols Explained

The triangle symbol indicates whether and how you can bleach the garment. Bleaching is important for stain removal on white fabrics.

Drying Symbols Explained

The square symbol covers all drying instructions. A circle inside the square indicates tumble dry (machine drying). Without the circle, the symbol refers to natural drying methods.

Dryer tip: When using a laundromat dryer, start with the recommended heat level from the care label. Over-drying on high heat is the leading cause of clothes shrinking and fabric damage. For more on protecting your clothes in the dryer, read our dryer safety guide.

Ironing Symbols Explained

The iron-shaped symbol tells you whether and at what temperature you can iron the garment. Dots inside the iron indicate heat levels.

Dry Cleaning Symbols Explained

The circle symbol indicates professional cleaning instructions. These are primarily for dry cleaners and dry cleaning services, but understanding them helps you communicate with your cleaner.

Quick Reference: Most Common Laundry Symbols

You don't need to memorize every symbol. Here are the ones you'll encounter most often:

• Washtub + 40°C: Machine wash warm — the most common washing instruction for everyday clothes
• Triangle with X: Do not bleach — standard for colored garments
• Square with circle + 2 dots: Tumble dry medium — safe for most cottons and blends
• Iron with 2 dots: Iron medium heat — works for most fabrics
• Hand wash symbol: Handle with care — use the delicate cycle at a laundromat if hand washing isn't practical

When in doubt, wash cold and tumble dry low — this is the safest default for most garments and causes the least wear on fabrics.

Frequently Asked Questions About Laundry Symbols

What does the triangle symbol on clothing mean?
The triangle on a care label indicates bleaching instructions. An empty triangle means any bleach is safe. A triangle with diagonal lines means oxygen bleach only. A crossed-out triangle means do not bleach.

What does the circle on a care label mean?
The circle symbol refers to professional dry cleaning. Letters inside the circle tell the dry cleaner which solvents to use. A crossed-out circle means do not dry clean.

What does the square with a circle mean on a care label?
A square with a circle inside means tumble dry (machine drying). Dots inside indicate heat level: one dot = low, two dots = medium, three dots = high.

What if the care label is missing or unreadable?
When you can't read the label, default to the safest settings: wash cold on a gentle cycle, tumble dry low or air dry, and test-iron on a hidden area first. Check our fabric care guide for material-specific recommendations.

Laundry care symbols follow the international standard ISO 3758, used in most countries worldwide. US care labels may also include written instructions per FTC requirements.
