Read a T-shirt’s care symbols in order: washing, bleaching, drying, ironing, then professional textile care. The symbols set the maximum or permitted treatment intended to avoid damage to that garment; they do not promise that stains will come out. Follow the shirt’s own label rather than guessing from its fabric name or copying another shirt’s instructions.
What the care-label system covers
ISO 3758:2023, published in December 2023, is the current edition identified on ISO’s standard page. It specifies a symbol code for domestic washing, bleaching, drying and ironing, as well as professional dry and wet cleaning, subject to the standard’s stated exclusions. ISO 3758:2023
Care symbols apply to the textile article as a whole, not just its main fiber. Color, finishes, buttons, zippers and other attached details can affect what treatment is suitable. That is why “100% cotton” is not enough to determine whether a particular T-shirt can be washed hot or tumble-dried. Use the instructions on that shirt’s label. GINETEX’s care-labelling overview
How to read the five symbol families
Read the sequence from left to right (or top to bottom, depending on the label): washing, bleaching, drying, ironing and professional textile care. A cross over a symbol means the treatment it represents is not permitted. GINETEX’s care-symbol explanations

#1 Best Overall
- SIZE AND CARE IN ONE LABEL: More than a simple clothing size tag, each label combines a clear XS-2XL size marking with five printed care symbols, helping keep essential sizing and garment care information together in one compact label
- 5 PRINTED CARE INSTRUCTIONS: Each garment label shows Machine Wash at 30°C, Do Not Line Dry, Low Iron and Do Not Dry Clean symbols, giving wearers practical alongside the clothing size
- 120 LABELS, XS TO 2XL: Includes 20 labels each in XS, S, M, L, XL and 2XL for 120 pieces total; each white fabric label measures approximately 1.57 x 0.79 in, making it easy to stock multiple common adult apparel sizes
- IRON ON, NO SEWING NEEDED: Apply these fabric size labels with heat instead of sewing individual tags into place, a convenient option for adding size and care information to compatible finished garments and sewing projects
- MADE FOR EVERYDAY APPAREL: Suitable for shirts, T-shirts, blouses, dresses, coats, jumpsuits and other compatible garments where clear size identification and basic washing, drying and ironing guidance are useful
1. Washing: the washtub
A number inside the washtub gives the maximum washing temperature in degrees Celsius. Do not exceed it. A single bar beneath the tub calls for a milder process with reduced mechanical action; two bars call for a very mild process. A lower temperature or gentler cycle than the maximum shown is allowed when appropriate.
2. Bleaching: the triangle
- An empty triangle permits bleaching with any type of bleaching agent.
- A triangle with diagonal stripes permits oxygen-based, non-chlorine bleach only.
- A crossed triangle means do not bleach.
3. Drying: the square
The square frames drying instructions. A circle inside it means tumble drying; dots inside that circle indicate the permitted heat severity. A square without a circle can indicate natural drying methods. If the label does not show a tumble-dry symbol, do not assume the garment is dryer-safe: GINETEX notes that washing and ironing symbols provide some drying indications, but appliance suitability cannot be determined clearly for every textile from program wording alone.

4. Ironing: the iron

5. Professional textile care: the circle
A circle indicates professional textile care. Letters inside it identify the process or solvent, while bars beneath it indicate a milder process. If the label calls for professional dry or wet care, take the garment to a qualified cleaner rather than trying to interpret the process as a home-care instruction.

Can you put a T-shirt in the dryer?
Check the square symbol on that T-shirt’s label. A square containing a circle indicates tumble drying, and its dots show heat severity; a crossed version means not to use the represented drying treatment. Do not infer dryer safety from the word “cotton” or from another shirt’s label. When no tumble-dry symbol appears, follow any explicit restrictions and avoid treating appliance program names as a substitute for the care label.
What the symbols do—and do not—promise
The label describes the maximum or permitted care treatment intended to prevent damage to the article. A more conservative treatment—such as a lower wash temperature or gentler cycle—is allowed. But a care label is not a stain-removal guarantee: following its instructions does not ensure that all dirt or stains will come out. GINETEX

How to make a laundry-room sign or chart
Use the same five-family order as a garment label so people can scan a sign consistently: washing, bleaching, drying, ironing and professional textile care. Include the distinctions people are most likely to need: wash temperature and underlines, bleach permissions, tumble versus natural drying, heat dots, professional-care letters and the crossed-out prohibition.
GINETEX publishes an official table showing the symbol families and their variants; consult it when checking a chart’s accuracy: Table of Textile Care Symbols. The care symbols are protected trademarks in most countries, and reproduction or commercial use requires an appropriate license agreement. Before reproducing symbol artwork on a sign, verify the rights and local rules that apply; an official-looking chart is not automatically free to copy. GINETEX’s care-labelling overview
