Machine wash, delicate
An ISO 3758 washtub with two bars beneath it, calling for a very gentle mechanical action — the most cautious machine-wash setting.
What it means
The double underline signals the gentlest machine cycle: minimal agitation, a very low spin and a generous water level so the fabric floats rather than rubs. It is used for fragile knits, fine synthetics and loosely woven fabrics.
What to do
Run the delicate or hand-wash machine programme and place the item in a mesh laundry bag to reduce stretching and snagging. Use a mild detergent and skip the high-speed spin to avoid permanent creases.
How to use this term
Use this washing symbol before choosing water temperature, cycle intensity or whether the item should go in the machine at all.
- Read machine wash, delicate with the other symbols on the same care label; the strictest symbol wins.
- Match the instruction to the garment's most fragile part, including trims, lining, prints and finishes.
- If the label, fabric behaviour and stain method disagree, test a hidden area or choose the lower-risk route.
Common mistake
Do not upgrade to a hotter or heavier cycle because the stain looks stubborn; the strictest care symbol still sets the limit.
For the broader method, use the Laundry temperature guide and then return to this term when the label changes the safe option.
