THE SHORT ANSWER

What does it mean?

Tumble drying is allowed at normal heat (ISO exhaust-air temperature up to 80°C).

01 / HOW TO IDENTIFY IT

Match the shape, not just the words.

Look for a square enclosing a circle. Dots indicate dryer heat; a diagonal cross prohibits the machine tumble-drying process.

A square with a circled drum and two dots indicates normal tumble drying, corresponding to the public international guide’s normal-process thermal limit.

02 / WHAT TO DO

The practical decision.

Check the entire care label before selecting a heat setting, including written warnings about trims or layered finishes. The symbol grants a maximum treatment, not a requirement to machine dry.

Do not skip this detail

Do not use a hotter setting than the care label permits.

03 / WHAT PEOPLE CONFUSE

One small detail changes the meaning.

One dot instead signals a milder, lower-temperature process; a cross over the drum prohibits tumbling.

04 / AFTER YOU IDENTIFY IT

Check the rest of the tag.

The washing, bleaching, drying, ironing and professional-care instructions work together. This page interprets one symbol only; a blank or unreadable mark does not grant permission for any other treatment.

Never replace the maker’s written instructions with a guess based only on material composition or appearance. Read the complete care-label method.
