Laundry Symbols Explained: How to Read Clothing Care Labels
A favorite sweater’s care label can make the difference between keeping its shape and shrinking after one wash. Those tiny laundry symbols tell you how much heat and handling a garment can tolerate—and washing is only part of the story. Checking the drying, bleaching, and ironing instructions before you start helps you choose a complete care routine.
Start with the five basic shapes
Most clothing care labels use variations of five main symbols:
| Shape | What it covers |
|---|---|
| Wash tub | Hand or machine washing |
| Triangle | Bleaching |
| Square | Drying |
| Iron | Ironing |
| Circle | Professional cleaning |
The marks inside and beneath these shapes add detail. A cross means the pictured treatment is prohibited. Dots usually indicate temperature, while bars beneath a washing symbol call for gentler handling.
If a mark is difficult to distinguish, compare it with GINETEX’s illustrated guide to clothing care symbols before choosing a setting.
Washing symbols explained
The wash tub tells you whether home washing is suitable, along with the temperature and type of cycle to use.
Numbers and dots: water temperature
A number inside the tub gives the maximum washing temperature in degrees Celsius. Common examples include:
- 30°C / 86°F: A low-temperature wash.
- 40°C / 104°F: A warmer wash.
- 60°C / 140°F: A hot wash.
These are upper limits; you do not have to use the hottest permitted setting for every load.
Some labels use dots instead. On common U.S. labels, one dot indicates cold, two warm, and three hot, with additional dots representing higher temperature limits. Read any accompanying words for clarification.
Bars, hands, and crosses: washing method
Look beneath the tub as well as inside it:
- No bar: A normal washing process is permitted.
- One bar: Use a milder process with reduced agitation. U.S. labels commonly associate this with permanent press.
- Two bars: Use a very mild process, commonly labeled delicate or gentle.
- A hand in the tub: Hand wash, following any temperature instructions.
- A crossed-out tub: Do not wash, either by hand or machine. Check the professional cleaning instructions.
Temperature and cycle are separate choices. Selecting cold water does not make a normal cycle gentle, and a quick wash is not necessarily suitable for delicate clothing.
For a hand-wash garment, handle it gently rather than scrubbing or twisting it. Do not assume your machine’s “hand wash” program is an approved substitute.
Bleaching symbols: check the triangle
The triangle applies to bleach used during washing and in stain treatments.
- Empty triangle: Chlorine or oxygen bleach is permitted when needed.
- Triangle with two diagonal lines: Only oxygen, or non-chlorine, bleach is permitted.
- Crossed-out triangle: Do not use bleach.
“Color-safe” bleach is still bleach. A crossed-out triangle means you should also check detergents, boosters, and stain removers for bleaching ingredients.
An empty triangle gives permission to bleach; it does not mean every wash needs it. Follow the product’s directions as well as the garment label.
Drying symbols: distinguish machine drying from air drying
A garment that tolerates machine washing may still need careful drying. Read the square before transferring anything to the dryer.
A circle inside a square: tumble drying
This combination refers to a tumble dryer. Dots inside it indicate the permitted heat level.
On common U.S. labels, one dot means low heat, two medium, and three high. International labels commonly use one dot for lower-temperature drying and two for normal-temperature drying, so match the symbol system and written instructions on your garment.
A crossed-out square containing a circle means do not tumble dry. A low-heat setting does not override that instruction.
Some labels also place bars beneath the tumble-drying symbol to request a permanent-press or gentle cycle.
Lines inside a square: natural drying
Lines show how to position the garment while it dries:
- One horizontal line: Dry flat.
- A curved hanging line, or one vertical line in the international system: Line dry or hang to dry.
- Multiple vertical lines: Drip dry, without first wringing out the garment.
- Diagonal lines in a corner: Carry out the indicated drying method in the shade.
International labels may also show two horizontal lines for drip drying flat.
For a garment marked “dry flat,” use a clean, flat drying surface and gently arrange it into shape. Hanging a wet knit can stretch it under its own weight.
Ironing symbols: count the dots
The iron shape is easy to recognize. Its dots indicate the permitted heat level:
- One dot: Low.
- Two dots: Medium.
- Three dots: High.
- Crossed-out iron: Do not iron.
Match the dots to your iron’s controls and follow any printed temperature limit. Exact temperature specifications can vary between labeling standards, so avoid choosing a setting from the fabric name alone.
Steam needs a separate check. Crossed-out steam lines mean no steam, and low-temperature ironing should not automatically be treated as permission to steam. Follow written instructions such as “iron on reverse” or “use a pressing cloth.”
Professional cleaning symbols: read the circle
Letters inside a circle give instructions to a professional cleaner:
| Mark | Meaning |
|---|---|
| P inside a circle | Professional dry cleaning with specified solvents, including perchloroethylene and hydrocarbons |
| F inside a circle | Professional dry cleaning with hydrocarbon solvents |
| W inside a circle | Professional wet cleaning |
| Crossed-out dry-cleaning circle | Do not dry clean |
| Crossed-out W circle | Do not professionally wet clean |
Bars beneath professional cleaning symbols indicate a more restricted or gentler process.
Professional wet cleaning uses controlled equipment and techniques. A W symbol does not authorize washing the garment at home.
Likewise, a dry-cleaning symbol does not automatically mean “dry clean only.” The label may permit both washing and professional cleaning. Check the wash tub and any written wording before deciding.
Use the whole care label to choose a method
Read every instruction before treating a stain or starting a load. Fiber content provides useful context, but linings, dyes, prints, trims, and garment construction can affect how the finished piece should be cleaned.
Consider this example:
A top has a 30°C wash tub with two bars, a crossed-out triangle, a square with one horizontal line, and a one-dot iron. The wording adds “Wash inside out. Reshape while damp.”
The complete routine would be to turn it inside out, use a very gentle wash at no more than 30°C with bleach-free detergent, reshape it while damp, and dry it flat. If ironing is needed, use low heat. Reading only the wash temperature would miss several essential steps.
When sorting a load, group garments with compatible temperatures, cycles, colors, and drying methods. Clothes that can wash together may still need separating afterward.
If instructions are missing, unreadable, or contradictory, ask the manufacturer or a professional cleaner before experimenting. Photographing a clear care label also gives you a useful reference if it fades or becomes uncomfortable to keep attached.
