Why These Symbols Matter
Those small pictograms on your garment's care label are an international language, standardised to give you the best advice on how to care for your clothes. Following them prevents shrinking, fading, and fabric damage, extending the life of your favourite
pieces. It’s a simple step that saves money and frustration in the long run. The system is built around five core symbols: a washtub for washing, a triangle for bleaching, a square for drying, an iron for ironing, and a circle for professional cleaning. Variations on these five shapes tell you everything you need to know.
The Washtub: Washing Instructions
The washtub symbol is your guide to the washing machine. An empty tub generally means a normal wash cycle. A number inside the tub indicates the maximum water temperature in Celsius; for example, 30 means a cold wash at 30°C, and 40 means a warm wash at 40°C. Sometimes, dots are used instead: one dot for cold (around 30°C), two for warm (40°C), and three or more for hot (50°C and up). A line underneath the tub symbol means the garment needs a gentler cycle, like permanent press. Two lines indicate a very gentle or delicate cycle is required, often for wool or silk. A hand in the tub means hand wash only, and a large 'X' through the tub means do not wash at all.
The Triangle: To Bleach or Not to Bleach
The triangle symbol governs the use of bleach. An empty, open triangle means any type of bleach, including chlorine-based ones, is safe to use. If the triangle has two diagonal lines inside it, you should only use a non-chlorine or oxygen-based bleach. These are typically found in 'colour-safe' detergents. A solid black triangle with an 'X' over it is the most critical one in this category: do not use bleach of any kind. Ignoring this symbol can lead to irreversible colour loss or fabric damage.
The Square: Drying Rules
The square symbol tells you how to dry your clothes. A plain square on its own refers to air drying. A square with a circle inside it means the item can be safely tumble-dried. Dots inside this circle indicate the heat setting: one dot is for low heat, two for medium, and three for high. A solid black circle means you should use the 'no heat' or 'air only' setting on your dryer. A large 'X' through the tumble dry symbol means do not put it in the dryer. Other variations inside the plain square give instructions for natural drying: a horizontal line means to dry flat, a curved line means to hang dry, and vertical lines often mean to drip dry.
The Iron: Pressing Matters
The iron symbol is fairly straightforward and advises on ironing temperature. An iron with one dot inside means you should use a low-temperature setting, typically for delicate fabrics like silk or synthetics. Two dots allow for a medium heat setting, suitable for many synthetic blends and wool. Three dots indicate that a high heat setting can be used, which is usually reserved for cotton and linen. As with the other symbols, an 'X' drawn through the iron means the garment should not be ironed at all. Some labels may also show a crossed-out symbol for steam, indicating you should iron dry.
The Circle: When to Call a Professional
The circle symbol is for professional dry cleaning. A simple empty circle means the item is dry-clean only. An 'X' through the circle means the item should not be dry-cleaned. Letters inside the circle (like 'P' or 'F') are instructions for the dry cleaner, indicating which solvents they should use. An underlined circle suggests a gentler dry cleaning process is needed. For most people, the main takeaway is simple: if you see a circle, it’s best to take that garment to a professional cleaner rather than attempting to wash it at home.
