The Five Basic Shapes of Laundry Care
At first glance, the symbols can seem like a random collection of shapes. However, they are part of a standardised international system. Almost every instruction falls into one of five categories, each represented by a basic shape. A washtub represents
washing, a triangle represents bleaching, a square is for drying, an iron shape is for ironing, and a circle is for professional dry cleaning. Once you know these five fundamental symbols, you're halfway to cracking the code. Variations on these shapes provide more specific instructions, like temperature and cycle type.
Washing Symbols Decoded
The washtub symbol gives you the most critical information: how to wash the item. If the tub has an 'X' through it, it should not be washed in a machine. A hand in the tub means hand wash only. Numbers inside the tub, common in Europe, indicate the maximum water temperature in Celsius (e.g., 30, 40). In other regions, dots are used: one dot for cold, two for warm, and three for hot. Underneath the tub, you might see lines. No line means a normal cycle is fine. One line indicates a 'permanent press' cycle, which is gentler. Two lines mean you should use a delicate or gentle cycle, for items that need extra care.
Bleaching Rules Made Simple
The triangle symbol is all about bleaching. An empty, plain triangle means that any type of bleach, including chlorine-based ones, can be used when needed. If you see a triangle with two diagonal lines inside it, you should only use non-chlorine or oxygen-based bleach. This is common for colours and delicate fabrics. A solid triangle with an 'X' through it is a clear warning: do not bleach the garment at all. Using bleach on these items can cause permanent damage, discolouration, or weaken the fabric.
Mastering Drying Symbols
The square symbol is your guide to drying. A square with a circle inside it means the item is safe for the tumble dryer. Just like the washing symbols, dots inside the circle indicate the heat setting: one dot for low heat, two for medium, and three for high. An 'X' through the tumble dry symbol means you should keep it out of the machine and air dry it instead. The square has other variations for natural drying. A square with a curved line at the top means line dry. A square with a horizontal line in the middle means to dry the item flat. Three vertical lines in the square mean drip dry.
Ironing Without Incidents
The iron symbol tells you whether you can press your garment and at what temperature. An iron with an 'X' through it means the item should not be ironed. Dots inside the iron correspond to heat levels. One dot signifies low heat, suitable for delicate fabrics like silk and synthetics. Two dots mean medium heat, which is good for wool and blends. Three dots indicate high heat, best for durable materials like cotton and linen. Some symbols may also show an 'X' over the steam coming from the bottom of the iron, which means you should iron without using steam.
For the Professionals: Dry Cleaning
The simple circle symbol indicates that a garment should be professionally dry-cleaned. An 'X' through the circle means do not dry clean. Sometimes, you'll see letters inside the circle, such as 'A', 'P', or 'F'. These are not instructions for you, but rather for the professional cleaner, telling them which type of chemical solvent to use for the best results. An 'A' means any solvent, 'P' means petroleum-based solvents, and 'F' indicates specific hydrocarbon solvents are required. If you see a circle, it's best to leave the cleaning to the experts.
