Most people read a care label the way they read terms and conditions: a glance, a shrug, and straight into the machine. Then a sweater comes out smaller, and that row of tiny pictures suddenly matters.
Laundry symbols are not a secret code. There are five basic shapes, and every other mark is a modifier: dots for heat, bars for gentleness, an X for “don’t.” Learn the shapes and you can read almost any tag in seconds.
Below, every common laundry care symbol is described in words, family by family, in the order it appears on a tag, with extra detail on the dry clean symbol, the one customers ask us about most.

Key takeaways
- Every care label is built from five shapes: a tub for washing, a triangle for bleach, a square for drying, an iron for ironing and a circle for professional cleaning.
- On US labels, dots mean temperature: one dot is the coolest setting and more dots mean more heat, for washing, tumble drying and ironing alike.
- Bars under a symbol mean a gentler cycle: one bar is permanent press, two bars is delicate or gentle.
- An X through any symbol means do not do it: the maker expects that step to damage the garment.
- A letter inside the dry clean circle is an instruction for your cleaner, not for you.
The five shapes behind all laundry symbols
Care labels in North America use a symbol system published by ASTM International as standard D5489. According to a University of Tennessee Extension care symbols guide, laundering instructions include, at minimum, four symbols in a set order: washing, bleaching, drying and ironing. Dry cleaning instructions use one symbol.
Clothing made for Europe uses the closely related ISO 3758 system, whose symbols are registered by the labelling association GINETEX. The shapes match; a European tub simply shows degrees Celsius where an American one shows dots.
| Shape | Family | What it covers |
|---|---|---|
| Tub filled with water | Washing | Machine or hand washing, cycle and water temperature |
| Triangle | Bleaching | Whether bleach is allowed, and which kind |
| Square | Drying | Tumble drying, heat level, or natural drying |
| Hand iron | Ironing | Whether to iron, how hot, and whether steam is safe |
| Circle | Professional care | Dry cleaning or professional wet cleaning |
Three modifiers work across all five: dots mean heat, bars underneath mean a gentler process, and an X through the symbol means “do not.”
Washing symbols: the tub
The washing symbol looks like a small bucket or tub with a wavy line across the top for the water surface. It tells you whether the garment can be washed at home, on which cycle, and how hot the water can be.
| What you see | What it means |
|---|---|
| Plain tub | Machine wash, normal cycle |
| Tub with one bar underneath | Machine wash, permanent press cycle |
| Tub with two bars underneath | Machine wash, delicate or gentle cycle |
| Tub with a hand dipped into it | Hand wash only |
| Tub with an X through it | Do not wash |
| Twisted cloth with an X through it | Do not wring |
The dots inside the tub set the maximum water temperature. The Tennessee Extension chart, which is drawn from the ASTM standard, lists them this way:
| Dots in the tub | Maximum water temperature |
|---|---|
| One dot | 30°C (65-85°F), cold |
| Two dots | 40°C (105°F), warm |
| Three dots | 50°C (120°F), hot |
| Four dots | 60°C (140°F) |
| Five dots | 70°C (160°F) |
| Six dots | 95°C (200°F) |
In everyday terms, one dot is cold, two is warm and three is hot. Like all laundry symbols that show heat, the dots are a ceiling, not a target: cold water is kinder to colour and fit. Our guide on keeping clothes from shrinking in the wash explains why heat and agitation are the usual culprits.
Bleaching symbols: the triangle
The bleach symbol is a simple triangle, and there are only three versions to learn.
| What you see | What it means |
|---|---|
| Empty triangle | Any bleach may be used when needed |
| Triangle with two diagonal lines inside | Only non-chlorine (oxygen) bleach |
| Triangle with an X through it, sometimes filled in black | Do not bleach |
The diagonal-lines version is the one people misread most often. It does not mean “no bleach.” It means chlorine bleach will damage the colour or fibre, but a colour-safe oxygen bleach is acceptable. GINETEX’s own care symbols reference describes the two oblique lines exactly this way: oxygen bleach permitted, chlorine not.
Drying symbols: the square
A square means drying. What sits inside the square tells you how.
Tumble drying
A circle inside the square means tumble dry. The dots inside that circle set the heat, and bars underneath the square set the cycle.
| What you see | What it means |
|---|---|
| Square with an empty circle | Tumble dry, any heat |
| Circle with one dot | Tumble dry, low heat |
| Circle with two dots | Tumble dry, medium heat |
| Circle with three dots | Tumble dry, high heat |
| Circle filled in solid black | Tumble dry with no heat (air only) |
| One bar under the square | Permanent press cycle |
| Two bars under the square | Delicate or gentle cycle |
| Square and circle with an X through them | Do not tumble dry |
| Plain square with an X through it | Do not dry (paired with do not wash) |
Natural drying
Lines inside the square, with no circle, mean the garment should dry without a machine.
| What you see | What it means |
|---|---|
| Square with a curved line hanging from the top edge | Line dry or hang to dry |
| Square with three vertical lines | Drip dry: hang it up soaking wet, without spinning or wringing |
| Square with one horizontal line in the middle | Dry flat |
| Diagonal lines in the top-left corner | Dry in the shade (added to any of the above) |
Take that “in the shade” mark seriously in Mesa. Our sun fades dark and bright fabrics on a backyard line quickly, and the shade symbol appears on exactly the garments that fade easiest.
Ironing symbols: the iron
The ironing symbol is a small hand iron seen from the side. Dots inside it set the maximum soleplate temperature. The ASTM figures in the Tennessee chart are:
| What you see | What it means |
|---|---|
| Iron with one dot | Low: up to 110°C (230°F) |
| Iron with two dots | Medium: up to 150°C (300°F) |
| Iron with three dots | High: up to 200°C (390°F) |
| Iron with an X through it | Do not iron |
| Iron with crossed-out lines underneath | Iron, but no steam |
European labels use the same dots with slightly higher soleplate maximums. Either way, one dot is the synthetics setting, two is roughly wool and silk, three is cotton and linen. Our guide to ironing a dress shirt in the right order puts those settings to work.
The dry clean symbol: the circle and its letters
A plain circle is the dry clean symbol. It means the garment can be professionally dry cleaned. A circle with an X through it means do not dry clean.
The letters sometimes printed inside the circle tell the cleaner which solvents the fabric, trims and dyes can tolerate.
| What you see | What it tells your cleaner |
|---|---|
| Plain circle | Can be dry cleaned |
| Circle with A | Any solvent (ASTM labels) |
| Circle with P | Any solvent except trichloroethylene (ASTM); on ISO labels, perchloroethylene or hydrocarbon solvents |
| Circle with F | Petroleum or hydrocarbon solvent only |
| Circle with W | Professional wet cleaning is allowed |
| Circle with one bar underneath | A milder process is needed |
| Circle with two bars underneath (usually under W) | A very mild process is needed |
| Circle with an X through it | Do not dry clean |
US labels can also add small marks around the outside of the circle for short cycle, reduced moisture, low heat or no steam finishing.
What the letters mean for you as a customer
Honestly, very little, and that is by design. The letters are a note from the manufacturer to the professional. You do not need to know what a hydrocarbon solvent is or pick one. What does matter to you:
- Keep the label. If you cut it out, tell us what the garment is made of.
- A bar under the circle means a gentler touch than usual is needed.
- A W is not an invitation to wash it at home. GINETEX notes that professional wet cleaning relies on equipment and finishing methods a household machine cannot match.
- An X through the circle is a real warning: solvent will damage something, often a trim, coating or print.
If you are curious what happens after you hand a garment over, we explain it step by step in what dry cleaning actually is.
Why the rules behind laundry symbols matter to you
Care labels in the US are not decoration. The Federal Trade Commission’s Care Labeling Rule requires clothing makers and importers to give care instructions, and the FTC’s business guide, Clothes Captioning: Complying with the Care Labeling Rule, sets out what those instructions must cover.
What that guidance means for you as a shopper:
- Symbols can replace words. The FTC says symbols are optional as long as care instructions are on the label, and the set it accepts is ASTM D5489. That is why some tags show only laundry symbols with no text.
- The label only has to give one safe method. “Dry clean” tells you dry cleaning is safe, not that washing would ruin it.
- “Dry clean only” is different. The FTC treats “only” as a warning that the garment cannot be washed safely.
- Warnings are required when a normal step would do harm, such as “do not iron” or the crossed iron.
The Tennessee Extension guide adds that a garment labelled washable may not dry clean well, and the reverse. The symbols tell you what has been tested, not every option.
When a label says bring it to a professional
Some laundry care symbols are a clear signal to stop and hand the garment over:
- A circle with no tub, or a tub with an X: the maker has not approved home washing.
- A circle with a bar or with F: the garment needs a restricted, gentle process.
- Do not wash, do not tumble dry and do not iron on one tag: little is safe at home.
- A tailored jacket, a lined coat, silk or beading, whatever the label says, because the structure inside is easy to distort.
Our dry cleaning service handles suits, dresses and delicates, and the label is the first thing we look at. For shirts you would rather not iron yourself, our laundry and pressing service follows the same tag you would.
The bottom line
Laundry symbols are five shapes and three modifiers. Read the tag left to right: wash, bleach, dry, iron, professional care. Dots are heat, bars are gentleness, an X is a warning.

Frequently asked questions
What does a circle mean on a clothing tag?
A circle on a clothing tag means the garment can be professionally cleaned. A plain circle means dry cleaning is allowed, a letter inside tells the cleaner which solvents are safe, and a W means professional wet cleaning. A circle with an X through it means do not dry clean. A circle inside a square is different: that is the tumble dry symbol.
What does the triangle mean on laundry symbols?
The triangle is the bleach symbol. An empty triangle means any bleach can be used when needed, including chlorine. A triangle with two diagonal lines inside means use only non-chlorine, oxygen-based bleach. A triangle with an X through it, sometimes shaded black, means do not bleach at all, so skip bleach and any detergent that contains it.
What do the dots mean on laundry care symbols?
The dots mean temperature, and more dots always mean more heat. In the washing tub, one dot is cold, two is warm and three is hot. Inside a tumble dry circle, one dot is low heat, two is medium and three is high. On the iron symbol, one dot is the low setting and three dots is the hottest.
What does the square with a circle inside mean?
A square with a circle inside means the garment can go in a tumble dryer. Dots in the circle set the heat, from one dot for low to three for high, and a solid black circle means no heat. Bars under the square ask for a permanent press or delicate cycle. An X through the whole symbol means do not tumble dry.
Can I wash something that shows only the dry clean symbol?
Sometimes, but the label is not promising it will survive. A dry clean symbol without a washing tub tells you the maker has tested dry cleaning, not that washing is forbidden. If the tag says “dry clean only” or shows a crossed-out tub, take that as a real warning. For wool, silk, structured jackets and anything lined, we recommend bringing it in rather than experimenting.
