Dry cleaning symbols, and what each one means.
The circle is the one family on a care label not addressed to you. The letters inside tell a professional cleaner which solvent the article can take, and the bars underneath tell them how gently to run the process. You are not expected to act on any of it beyond handing the garment over.
P and F are dry cleaning, and they are not interchangeable: P allows perchloroethylene or hydrocarbons, F allows hydrocarbons only, so an F garment given the P process can be damaged. W is professional wet cleaning, which is a water process rather than a solvent one. A crossed-out circle rules that kind of cleaning out altogether.
Dry clean, any solvent
Professional dry cleaning in any solvent.
American labels only. ISO has dropped the A, since naming the permitted solvents is more useful to the cleaner than permitting all of them.
Professional wet cleaning
Professional wet cleaning, a water process, with no restrictions.
International only. The American chart in general circulation predates the W and does not carry it.
Do not wet clean
No professional wet cleaning.
International only, for the same reason as the W itself.
