--- title: "Do not tumble dry — what it means" description: "Do not put this in a tumble dryer at any temperature. What the symbol looks like, what happens if you ignore it, and where its meaning differs by country." url: https://atoneplace.net/symbol/laundry-do-not-tumble-dry/ site: "At One Place" --- # Do not tumble dry **Do not tumble dry: Do not put this in a tumble dryer at any temperature.** ## What it looks like *[Symbol drawn on the page: Do not tumble dry]* A square with a circle inside it and a cross through the whole thing. ## What it means The commonest reason is shrinkage that the wash alone would not cause: wool felts, cotton knit relaxes and then contracts, and anything with elastane loses its recovery permanently. It also covers items the dryer would damage mechanically — beading, sequins, foam-backed fabrics, waterproof membranes and bras with underwires. This symbol always appears with a natural-drying symbol telling you what to do instead; if it does not, dry flat is the safe default. > Defined by ISO 3758. Where a symbol differs between standards, the difference is described above rather than resolved — both versions are in circulation on real labels. ## Other laundry and care labels symbols | Symbol | Means | | --- | --- | | Wash (plain tub) | The item can be machine washed. | | Wash at 30 °C maximum | Machine wash at 30 °C (86 °F) or cooler. | | Wash at 40 °C maximum | Machine wash at 40 °C (104 °F) or cooler. | | Wash at 50 °C maximum | Machine wash at 50 °C (122 °F) or cooler. | | Wash at 60 °C maximum | Machine wash at 60 °C (140 °F) or cooler. | | Wash at 70 °C maximum | Machine wash at 70 °C (158 °F) or cooler. | | Wash at 95 °C maximum | Machine wash at 95 °C (203 °F) or cooler — a boil wash. | | Mild wash — one bar under the tub | Wash at the stated temperature but with reduced mechanical action — the permanent press or synthetics cycle. | | Very mild wash — two bars under the tub | Wash at the stated temperature on the gentlest machine cycle, with a much reduced load and spin. | | Hand wash only | Wash by hand at 40 °C (104 °F) or cooler.
