The washtub and the triangle, and everything drawn in or across them. ISO 3758 makes this a genuine system rather than a collection: a base shape says which process, and what is inside it says under what limits. The group contains the care symbol most often misread — a triangle with two diagonal stripes permits oxygen bleach and forbids chlorine, and nothing about the drawing signals that it is a restriction at all.
A tub-shaped outline with a wavy water line, the GINETEX base symbol for washing instructions on a garment care label.
Dots inside a washtub setting the maximum wash temperature.
A hand dipped into a washtub, permitting washing by hand only.
A washtub crossed out, forbidding washing in water altogether.
A twisted shape crossed out, forbidding wringing the garment.
A triangle outline, the GINETEX base symbol for bleaching instructions on a garment care label.
A triangle crossed out, forbidding bleach of any kind.
A triangle with two diagonal stripes, permitting non-chlorine bleach.
One or two bars under a care symbol, calling for a gentler process.
