GINETEX explains that the number inside a wash tub gives the maximum washing temperature in degrees Celsius. Bars beneath the tub add information about the process: one indicates a milder cycle, while two call for a very mild treatment. The temperature alone therefore does not communicate the complete instruction.

This distinction matters when selecting a machine program and load size for sensitive articles. GINETEX also treats drying, bleaching, ironing and professional cleaning as separate care operations. Read the whole label and its modifiers instead of assuming that two garments showing the same temperature can always receive the same handling throughout the laundry process.
