TL;DR
Every care label uses five symbol shapes: a tub for washing, a triangle for bleach, a square for drying, an iron for ironing, and a circle for professional cleaning. Dots inside a symbol mean heat -- more dots, more heat. Bars underneath mean be gentle -- more bars, gentler. An X through any symbol means do not do it at all.
What do laundry symbols mean?
Each of the five shapes covers one step in the care process, and the marks inside or under the shape modify it. Dots indicate temperature, bars indicate how much mechanical action the fabric can take, and a cross through the shape is a prohibition. Once you know the five shapes, any label anywhere reads the same way.
Why the label exists at all
In the United States, garment makers are required to provide care instructions and to have a reasonable basis for them. Importantly, the rule requires them to give one safe method -- not every safe method. That single distinction explains most of the confusion around care labels.

A label saying dry clean means the maker has verified that dry cleaning works. It does not mean they tested and rejected hand washing. They may simply never have tested it. Dry clean only versus dry clean recommended covers how much force that instruction actually carries.
The five symbol families
The tub: washing
A tub shape means machine washing is allowed.
- Dots inside the tub show water temperature. One dot is cold, roughly 85 degrees F. Two dots is warm, roughly 105 degrees F. Three dots is hot, roughly 120 degrees F. More dots means hotter.
- A number inside the tub on some international labels is the maximum temperature in Celsius.
- One bar under the tub means permanent press: reduced agitation and a slower spin.
- Two bars under the tub means delicate or gentle: minimal agitation.
- A hand in the tub means hand wash only. Not the gentle cycle, not a mesh bag -- by hand.
- A tub with an X through it means do not wash in water at all.
Bars map directly onto machine settings, and picking the right washer cycle explains what those settings change.
The triangle: bleach
- An empty triangle means any bleach is allowed.
- A triangle with diagonal lines inside means non-chlorine bleach only, which in practice means oxygen bleach.
- A triangle with an X means no bleach of any kind.
Two accuracy notes worth carrying beyond the label. Oxygen bleach is not safe on wool or silk even when a label is vague, because it attacks protein fiber. And chlorine bleach should never be combined with vinegar, ammonia, or any acidic cleaner, since those combinations release toxic gas.
The square: drying
A plain square covers drying generally.
- A circle inside the square means tumble drying is allowed.
- Dots inside that circle are dryer heat. One dot is low, two is medium, three is high.
- A filled black circle inside the square means tumble dry with no heat, the air fluff setting.
- Bars under the square mean permanent press or delicate dryer settings, same logic as the wash bars.
- A square with an X, or a circle with an X inside a square, means do not tumble dry.
- A curved line inside the top of the square means line dry, three vertical lines means drip dry, and two diagonal lines in the upper corner means dry in the shade.
- One horizontal line inside the square means dry flat, which is what wool and most knits need. See washing wool and cashmere at home.
The iron: ironing
- Dots inside the iron are heat. One dot is low, for synthetics and silk. Two dots is medium, for wool and blends. Three dots is high, for cotton and linen.
- An iron with an X means do not iron.
- An iron with lines crossed out beneath it means no steam.
If a garment says no iron but wrinkles badly, steaming is often a workable alternative. Iron versus clothes steamer covers when each tool is right.
The circle: professional cleaning
- A plain circle means dry clean.
- A letter inside the circle tells the cleaner which solvent to use. You do not need to interpret it; the cleaner does.
- A circle with an X means do not dry clean. This matters -- some garments are damaged by solvent even though they wash fine in water.
- A circle inside a square with a W means professional wet cleaning.
Where the fiber content tag matters more than the symbols
The composition tag next to the care symbols is often more useful than the symbols themselves, because fiber determines what is actually safe.
Wool and silk are protein fibers: no bleach of any kind, no hot water, minimal agitation. Elastane degrades in heat, so anything stretchy should stay out of a hot dryer regardless of what the symbols allow. Viscose, rayon, and modal lose significant strength when wet and can shrink or distort badly in water. Cotton shrinks in heat and tolerates almost everything else.
When the symbols and the fiber content seem to conflict, follow the more cautious reading.
When can you ignore a care label?
Rarely, and only in one direction: you can safely do something gentler than the label allows. Hand washing something rated for machine washing is fine. Air drying something rated for tumble drying is fine.
Going the other way is where garments get destroyed. Machine washing a hand wash item, tumble drying a flat dry item, or ironing something marked no iron are the mistakes that produce permanent damage.
What to do when the label is missing
Work from fiber and construction instead. Identify the fabric by feel, then default to the most cautious reasonable approach: cool water, gentle cycle or hand wash, no bleach, air dry flat. If the garment is structured, lined, or valuable, a professional cleaner can identify the fiber and choose a process.
FAQ
What do the dots on a laundry symbol mean?
Dots always mean heat. One dot is the lowest setting, two is medium, three is high, and more dots than that appear on some international labels for progressively hotter washing. The scale applies to the wash tub, the dryer circle, and the iron alike.
What do the bars under a symbol mean?
Bars mean reduce the mechanical action. One bar corresponds to a permanent press setting with a slower spin, and two bars corresponds to a delicate or gentle setting. No bar means the normal setting is acceptable.
Does a hand in the tub mean I can use the gentle cycle?
No. A hand in the tub means hand wash only. Even a machine hand wash cycle produces more movement than washing by hand, and for fragile items that difference is what causes the damage.
What if the care label and the fiber tag disagree?
Follow the more cautious of the two. If a garment is labeled machine washable but the fiber content lists a high percentage of viscose or wool, treat it as delicate. Fiber behavior is physical and does not change because a label was printed optimistically.
Do care symbols mean the same thing worldwide?
Mostly. The shapes are consistent across the American, European, and Japanese systems, though numbers inside the tub for Celsius temperatures are more common on imported garments and a few regional variations exist. The five shapes and the dot-and-bar logic hold everywhere.
