Every garment and household textile sold within the European Union must carry a care label displaying maintenance instructions using standardised symbols defined by ISO 3758:2012 (Textiles — Care labelling code using symbols). These symbols are organised into five categories: washing, bleaching, drying, ironing, and professional textile care. Misreading or ignoring them is one of the most common causes of irreversible fabric damage at home.
The Five Symbol Categories
1. Washing Symbols (Washtub)
The base symbol is a stylised washtub — a bucket shape with a wavy line at the top representing water. Numbers inside or dots beneath the tub indicate the maximum water temperature. A hand in the tub means hand-wash only. An X through the entire symbol means do not wash with water at all.
| Symbol Description | Meaning |
|---|---|
| Tub with 30 | Machine wash, maximum 30°C, normal process |
| Tub with 40 | Machine wash, maximum 40°C, normal process |
| Tub with 60 | Machine wash, maximum 60°C, normal process |
| Tub with one underline | Gentle / permanent press cycle — reduced mechanical action |
| Tub with two underlines | Very gentle cycle — minimal agitation (delicates) |
| Tub with hand | Hand wash only — do not machine wash |
| Tub with X through it | Do not wash with water |
The underline conventions are frequently misread. One underline does not mean the fabric is fragile — it means a gentler agitation cycle is appropriate, typically the "synthetics" or "permanent press" programme on most machines. Two underlines corresponds to the "delicates" or "wool" programme. The temperature specified still applies.
2. Bleaching Symbols (Triangle)
The triangle symbol represents bleaching. An empty triangle means any bleach may be used. A triangle with two diagonal lines (resembling CL inside) means only chlorine-free bleach is permitted. A filled-in (solid black) triangle with an X through it means no bleaching of any kind.
In Polish households, bleaching agents are most commonly used in the form of oxygen-based powders (e.g., Vanish OxiAction) rather than chlorine bleach. Chlorine bleach (wybielacz chlorowy) is available but is typically reserved for white cotton sanitary items and should never be used on wool, silk, or most synthetics.
3. Drying Symbols (Square)
Drying symbols use a square as the base shape. A circle inside the square indicates tumble dryer use. Dots inside the circle indicate temperature — one dot for low heat, two dots for medium heat. An X through the circle-in-square means do not tumble dry. Lines within the square (without a circle) indicate line drying, flat drying, or drip drying:
| Symbol Description | Meaning |
|---|---|
| Square with circle, one dot | Tumble dry on low heat |
| Square with circle, two dots | Tumble dry on medium heat |
| Square with circle, X | Do not tumble dry |
| Square with horizontal line (middle) | Dry flat (lay horizontally) |
| Square with vertical line (middle) | Line dry (hang vertically) |
| Square with curved top | Drip dry (hang without wringing) |
The flat-dry instruction is particularly important for wool garments. Hanging a wet wool item distorts the shape permanently due to the weight of the water. Knitwear sold in Poland frequently carries this symbol, especially in autumn and winter garment ranges.
4. Ironing Symbols (Iron)
The iron symbol is a stylised iron. Dots indicate the maximum plate temperature:
| Dots on Iron Symbol | Maximum Temperature | Suitable Fabrics |
|---|---|---|
| One dot | 110°C | Synthetics, acetate, acrylic |
| Two dots | 150°C | Polyester blends, wool (with damp cloth) |
| Three dots | 200°C | Cotton, linen |
| Iron with X | Do not iron | Delicate embellishments, crinkle fabrics |
| Iron with steam lines crossed | Iron without steam | Fabrics that water-spot (e.g., silk, velvet) |
5. Professional Textile Care (Circle)
A circle on its own indicates professional dry cleaning. Letters inside the circle (P, F, W) indicate which solvents are appropriate. A circle with an X means do not dry clean. Most household consumers in Poland do not need to interpret these symbols directly — if the circle appears without an X, the item can be taken to a pralnia chemiczna (dry cleaner) who will identify the correct process.
Common Misinterpretations
Dots vs. Numbers in Washtub
Some older garments use dots rather than numbers inside the washtub. One dot corresponds to 30°C, two dots to 40°C, three dots to 60°C, four dots to 95°C. This system was more common before ISO 3758 was revised in 2012 to standardise numeric temperatures. Both systems remain valid on products currently in circulation.
The Hand-Wash Symbol
Hand-wash does not necessarily mean the item cannot be placed in a machine. It means the standard machine-wash cycle is too aggressive. Modern washing machines with a "wool" or "hand-wash" programme often replicate the gentle agitation and low spin of true hand washing. Items labelled for hand-wash can frequently be machine-washed on these programmes — check the specific machine's manual for the applicable cycle specifications.
No Symbol Present
If no care label is present — either because it was cut out, or because the item predates labelling regulations — treat the item as if it is made from the most delicate fibre present in the blend. If uncertain, cold water and a delicate cycle is the safest default.
EU Textile Labelling Regulations
The mandatory use of care symbols on textiles sold within the EU is governed by Regulation (EU) No 1007/2011 on textile fibre names and related labelling. While this regulation primarily addresses fibre composition disclosure, care instructions are governed by the referenced ISO 3758 standard. The European Commission maintains a consumer-facing summary at ec.europa.eu — Textiles.
