Laundry symbols on care labels: a complete guide to reading them
A clothing care label holds all the information you need to make a garment last. Yet most of us don't pay attention to it — for some reason we cut it off without reading it. In fact, these little symbols tell you the maximum washing temperature, whether tumble drying is allowed, which ironing setting to use and whether bleaching is permitted. In this article: a complete guide to reading all the main symbols. You'll save clothes, money and time.
Why the care label matters so much
Laundry symbols on care labels are an international standard (ISO 3758, applicable in Lithuania through EU directives). They were designed specifically so that you can care for a garment safely, whatever language the label is written in.
A realistic example of why this matters:
- A wool jumper at 60 °C — shrinks to child size
- A polyester jacket in a tumble dryer on high heat — the fibres deform
- A silk tie with chlorine bleach — the colour is ruined
- A wool coat with a steam iron — the fibres deform
All of this can be avoided by spending 5 seconds checking the label before the first wash.
5 main groups of symbols
A label has 5 main categories, usually arranged in a row:
- Washing (wash tub symbol)
- Bleaching (triangle)
- Drying (square)
- Ironing (iron symbol)
- Professional cleaning (circle)
Let's go through each one:
1. Washing symbols (wash tub)
The main symbol is a wash tub (similar to an upside-down trapezium).
With a number inside
- Wash tub 30 — max. 30 °C
- Wash tub 40 — max. 40 °C
- Wash tub 60 — max. 60 °C
- Wash tub 90 — max. 90 °C
- Wash tub 95 — max. 95 °C (boiling water)
With bars underneath the symbol
Bars under the wash tub symbol show which cycle intensity is allowed:
- No bars — standard wash (all cycles)
- One bar — synthetics cycle (gentler)
- Two bars — wool / delicates cycle (gentler still)
Special symbols
- Wash tub with a hand inside — hand wash only
- Crossed-out wash tub — NEVER machine wash (dry clean only, or hand wash according to the other symbols)
2. Bleaching symbols (triangle)
- Empty triangle — may be bleached with chlorine and other bleaches
- Triangle with two lines (//) — non-chlorine (oxygen-based) bleach only
- Crossed-out triangle — NEVER bleach
For most modern clothes, only oxygen-based bleaching (sodium percarbonate) is recommended — it's safer for fibres and colours.
3. Drying symbols (square)
General symbols
- Empty square — may be dried
- Crossed-out square — do NOT dry (may only be hung in the shade)
Tumble dryer symbols (square with a circle)
- Empty circle inside — may be tumble dried
- Circle with one dot — low-temperature setting (max ~60 °C)
- Circle with two dots — medium temperature (max ~80 °C)
- Circle with three dots — high temperature
- Crossed-out circle — NEVER tumble dry
Natural drying symbols (square with lines)
- Vertical line inside — line dry
- Horizontal line inside — dry flat (important for woollens!)
- Three vertical lines — drip dry (without wringing)
4. Ironing symbols (iron)
- Iron with one dot — low temperature (max ~110 °C, synthetics)
- Iron with two dots — medium temperature (max ~150 °C, wool, silk)
- Iron with three dots — high temperature (max ~200 °C, cotton, linen)
- Iron with no dots — may be ironed at any temperature
- Crossed-out iron — NEVER iron
- Iron with crossed-out steam symbol — do not iron with steam
5. Professional cleaning (circle)
- Empty circle — may be dry cleaned (universal)
- Circle with the letter P — dry cleaning with perchloroethylene (PCE)
- Circle with the letter F — dry cleaning with hydrocarbons (kerosene)
- Circle with the letter W — professional wet cleaning
- Crossed-out circle — NEVER dry clean
Bars under the circle (just as with the wash tub symbol) show the cycle intensity — no bars, one or two.
Typical combinations and how to read them
Example 1: Wool jumper
Label: Wash tub 30 (with two bars) + Crossed-out triangle + Crossed-out circle (tumble dryer) + Square with a horizontal line + Iron with one dot + Circle with the letter P
Meaning: wash at max. 30 °C on a delicate cycle, do not bleach, do not tumble dry, dry flat, iron at a low temperature, may be dry cleaned with perchloroethylene.
Example 2: Cotton T-shirt
Label: Wash tub 40 + Triangle with lines + Circle with one dot + Iron with three dots
Meaning: wash at max. 40 °C, non-chlorine bleach only, tumble dry at a low temperature, iron at a high temperature.
Example 3: Silk dress
Label: Crossed-out wash tub symbol + Crossed-out triangle + Square (with a horizontal line) + Iron with one dot + Circle with P
Meaning: never machine wash, never bleach, dry flat in the shade, iron at a low temperature (preferably with a cloth in between), perchloroethylene dry cleaning only.
What to do if the label has been cut off
A classic situation. Without a label — choose your approach based on the material type and colour:
- Coloured cotton — 30 °C, enzyme laundry detergent
- White cotton — 40 °C, enzyme laundry detergent
- Synthetics — 30 °C, delicate cycle
- Wool — 30 °C, wool cycle, wool detergent
- Silk — dry cleaning is best, or hand wash in cold water
The safety principle: when in doubt, choose the more delicate option. Better a garment that isn't perfectly clean than one that's damaged.
How to identify a material without a label
There are a few tell-tale signs:
Visual and tactile
- Cotton — soft, slightly irregular fibres, feels smooth to the touch
- Wool — soft, warm, may feel slightly "fuzzy"
- Synthetics — slippery, often shiny, doesn't crease
- Silk — very lustrous, slippery, feels cool against the skin
- Linen — sturdy, slightly stiff, creases very easily
Burn test (on a small separate scrap)
Safely (outdoors or in the kitchen):
- Cotton — burns quickly, grey ash, smells like burning paper
- Wool — burns with difficulty, black ash, smells like burning hair
- Silk — burns with difficulty, smells like burning hair (similar to wool)
- Synthetics — melts, chemical smell
- Linen — burns quickly, smells like burning paper (similar to cotton)
Special cases
Blended fabrics
Most modern clothes are blends (cotton + synthetics, wool + acrylic). The label should reflect the characteristics of all the fibres. Strategy — follow the recommendations for the most delicate fibre.
Vintage or antique labels
Older labels may use outdated symbols. General rule: the older the garment, the more delicate the approach.
Designer clothing
Premium garments often carry not only the standard symbols but also additional written instructions. Always read the text too, not just the icons.
Practical tips
- Don't cut off the label for comfort — photograph or write down the symbols first
- Always go more delicate than stated — it extends the garment's life
- Wash and iron clothes inside out — protects the outer surface from friction
- Sort clothes by their labels — wash items with similar temperatures together
Ecozyme products by care label
Ecozyme enzyme laundry detergent is suitable for:
- Wash tub symbols 30 and 40 (all delicate and standard cycles)
- Coloured and white fabrics
- Synthetics and cotton
Ecozyme is NOT suitable for:
- Wool (proteases can damage wool protein)
- Silk (a delicate fibre)
- Garments with crossed-out wash tub symbols (dry clean only)
Frequently asked questions
Do international symbols apply in Lithuania?
Yes. As an EU member, Lithuania applies the ISO 3758 standard. All care label symbols should follow the international system.
Why does my silk dress only have crossed-out symbols?
It means the manufacturer recommends dry cleaning only. Many silk items can be carefully hand-washed at home, but you risk the colours and the fibre structure.
Is the ECO programme equivalent to the 30 °C symbol?
For most washing machines — yes, but not always. Eco programmes often run longer (compensating with time), but the temperature is similar. Check your washing machine's manual.
What should I do if a garment has shrunk?
You can only restore part of its original size, and only with a gentle method (in cold water with fabric softener, stretching it gently). But in most cases you won't get the original shape back. Prevention is better than cure.
Is the label really important for the first wash?
Yes. The first wash is critical. A new garment hasn't been tested yet, and mistakes can't be undone. Always follow the label instructions, especially the first time.
Summary
Care label symbols aren't decoration — they're an international code designed to make your clothes last longer. The main groups: wash tub (temperature and cycle), triangle (bleaching), square (drying), iron (ironing), circle (dry cleaning). Crossed-out symbols mean never. Bars under a symbol mean a more delicate cycle. A 5-second look at the label can save a garment that cost tens or hundreds of euros.
