How to read it

The circle is the professional cleaning symbol. A letter inside tells the cleaner which solvents can be used: in the Canadian government's guide, P means any solvent except trichloroethylene and F means petroleum solvent only. A W marks professional wet cleaning in water, and a bar under the circle calls for a milder process.

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

Differences by country or standard

In the GINETEX system, a bar under the circle warns the cleaner generally about possible harm from mechanical action, drying temperature or water added to the solvent. The US system, from ASTM, puts lines beside the circle at an angle instead, to show refinements; a University of Tennessee Extension guide lists short cycle, reduced moisture, low heat and no steam finishing among them.

The least understood symbol

In a survey of 6,000 people in six European countries, carried out by IPSOS for GINETEX in December 2016, the professional cleaning circle was the least understood care symbol: 21% of people interpreted it correctly.
