what does this symbol mean?
ISO 3758 A washtub with the number 30 and two lines underneath

Machine wash, 30°C, very mild

The item can be washed in water up to 30°C (86°F) on a very mild cycle.

Easily confused with

How to read it

Two bars under the washtub ask for a very mild wash with much less mechanical action, such as a wool wash cycle. The number is the highest water temperature allowed, in degrees Celsius. One bar means a mild cycle, and no bar the normal one.

Also searched as: delicates, wool wash.

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.

A detail few people notice

In a survey of 6,000 people in six European countries, carried out by IPSOS for GINETEX in December 2016, only one in four people noticed the bars under the care symbols. The dots in the ironing and tumble-drying symbols were noticed by about half (54%).
