How to read it

One bar under the washtub asks for a gentler wash than the normal cycle: less mechanical action, as GINETEX describes it for fine laundry such as modal, viscose and synthetic fibres. The number is the highest water temperature allowed, in degrees Celsius. Without the bar the normal cycle is allowed; with two bars the wash is very mild.

Also searched as: permanent press.

Where a garment's own label or its manufacturer says otherwise, that takes precedence.

Differences by country or standard

The international guide from GINETEX, the body behind the care symbols, names the settings by how gentle they are: one bar is a mild process and two bars a very mild process. The Canadian government's guide names the same settings after washing-machine cycles: one bar is permanent press and two bars delicate or gentle.

When the United States first allowed care symbols in place of words, in 1997, the Federal Trade Commission let manufacturers give permanent press or gentle cycle in words instead of bars, for anyone who thought the underlining might confuse Canadian or Mexican consumers, whose symbol systems didn't use it.
