Laundry Symbols Guide: What Every Care Label Means

You pull a brand-new sweater out of the washing machine only to discover it has shrunk two sizes. Sound familiar? The answer to preventing laundry disasters has been hiding in plain sight — on the care label sewn into every garment you own.

Those small laundry symbols printed on clothing tags are a universal language created so that anyone, anywhere, can understand how to properly wash, dry, iron, and bleach their clothes. The problem? Most people never learned how to read them.

In this complete guide, we'll decode every laundry care symbol you're likely to encounter, explain what they mean, and show you the easiest way to scan them instantly with your phone.

Washing Symbols: The Basics of Doing Laundry Right

The washing symbol looks like a small tub of water. It tells you whether a garment can be machine washed, what temperature to use, and how gentle the wash cycle should be.

Symbol	Meaning	What to do
	Machine wash	Safe for your regular washing machine cycle
	Wash at 30°C	Use a cold water setting to protect colours and fibres
	Wash at 40°C	Warm wash; suitable for cottons and everyday fabrics
	Wash at 60°C	Hot wash; good for towels, bed linens, and whites
	Hand wash only	Gently wash by hand in lukewarm water — no machine
	Do not wash	Take to a professional dry cleaner instead

Why Water Temperature Matters

Washing at the wrong temperature is the single most common reason clothes shrink, fade, or lose their shape. Cold water (30°C) is safest for most garments — it prevents colour bleeding and reduces energy consumption. Hot water (60°C) is best reserved for towels, bedding, and heavily soiled whites where you need the extra cleaning power.

Drying Symbols: Tumble Dry or Line Dry?

The drying symbol is represented by a square. It tells you whether a garment is safe for the tumble dryer and, if so, at what heat setting.

Symbol	Meaning	What to do
	Tumble dry allowed	Safe for the dryer at any heat setting
	Low heat tumble dry	Use the low heat or delicate dryer setting
	Normal heat tumble dry	Regular dryer setting is fine
	Do not tumble dry	Air dry only — hang up or lay flat
	Line dry	Hang garment on a clothesline to air dry
	Dry flat	Lay the garment flat on a surface to prevent stretching

If a garment says "do not tumble dry," respect it. Fabrics like wool, silk, and many synthetics can warp, pill, or shrink permanently in the dryer.

Ironing Symbols: Getting the Right Temperature

The ironing symbol is shaped like a classic iron. The dots inside indicate the maximum temperature you should use.

Symbol	Meaning	Temperature
	Low temperature iron	110°C — best for synthetics and silk
	Medium temperature iron	150°C — ideal for wool and polyester blends
	High temperature iron	200°C — for cotton and linen fabrics
	Do not iron	No ironing or steaming at all

Bleaching Symbols: When It's Safe to Whiten

The bleaching symbol is a triangle. It tells you whether any type of bleach can be used to remove stains or whiten the fabric.

• Empty triangle — Any bleach is allowed (chlorine or oxygen-based)
• Triangle with diagonal lines — Only non-chlorine (oxygen) bleach allowed
• Crossed-out triangle — Do not bleach at all

When in doubt, always opt for colour-safe, non-chlorine bleach. Chlorine bleach is very effective on white cotton fabrics but can permanently damage coloured clothing and delicate materials.

Dry Cleaning Symbols: What the Circle Means

The dry cleaning symbol is a circle. If you see one on your care label, it means the garment is best handled by a professional cleaner. The letter inside the circle tells the dry cleaner which solvent to use:

• P — Dry clean with perchloroethylene (common solvent)
• F — Dry clean with petroleum-based solvents only
• W — Professional wet cleaning
• Crossed-out circle — Do not dry clean

The Easiest Way to Decode Laundry Symbols

Memorising dozens of laundry symbols isn't practical for most people. That's exactly why we built Laundry Lens.

Laundry Lens is a free app that lets you scan any care label using your phone's camera. In seconds, it translates every symbol into plain, easy-to-understand instructions — telling you the exact temperature, cycle type, and drying method for that specific garment.

No more Googling "what does the square with a circle inside mean?" Just point, scan, and wash with confidence.

Quick Reference: 5 Laundry Care Categories

Every care label uses symbols from these five categories. Once you know what each base shape represents, reading any label becomes second nature:

1. Tub (Washing) — How to wash the garment: temperature, cycle type, or hand-wash only
2. Square (Drying) — How to dry: tumble dry heat level, line dry, or flat dry
3. Iron (Ironing) — Maximum ironing temperature and whether steam is allowed
4. Triangle (Bleaching) — Whether bleach can be used and what type
5. Circle (Dry Cleaning) — Whether professional cleaning is needed and which solvents are safe
