Professional care symbols
The circle family covers professional textile care, including dry cleaning and professional wet cleaning. A plain circle establishes the professional-care family, while a letter inside tells the cleaner which process or solvent class is permitted. The letter addresses the cleaner, not you, and it is not a home-care instruction.
Professional care appears last in the standard five-family row, after the iron. Its final position separates the cleaner's process information from the washing, bleaching, drying, and ironing steps you may carry out at home. The guide library shows the complete row so you can tell a stand-alone circle from the circle placed inside a drying square.
- Dry clean Take this to a dry cleaner. A plain circle means professional dry cleaning.
- Dry clean with "P" solvents Professional dry clean using "P" solvents: perchloroethylene (perc) or petroleum-based hydrocarbons.
- Dry clean, petroleum solvent (F) Professional dry clean using petroleum-based solvent only.
- Professional wet cleaning (W) An unbarred W means normal professional wet cleaning, a controlled water-based process.
- Do not dry clean Professional dry cleaning is prohibited. Do not use stain removers that contain solvents.
Read the circle before reading the letter
A plain dry-cleaning circle permits professional dry cleaning without naming a solvent. When a letter appears inside, the code identifies or limits a professional process. It does not name a detergent, machine cycle, or product for you to reproduce at home.
This outer-shape check also separates professional care from tumble drying. A professional-care mark is a circle standing on its own. A tumble-dry mark puts a circle inside a square. If you can trace four sides around the circle, you are in the drying family and any dots refer to dryer heat. If there is no surrounding square, read the circle as professional care.
Show the cleaner the whole label rather than copying a single letter. The other symbols still carry the garment's wash, bleach, dry, and iron limits, and the professional can read the circle in that complete context.
P, F, and W are process codes for the cleaner
Under ISO 3758 and ASTM D5489-18, P permits professional dry cleaning with perchloroethylene and hydrocarbon solvent classes. The FTC-recognized ASTM D5489-96c edition defines P as any solvent except trichloroethylene. F narrows professional dry cleaning to a petroleum-based hydrocarbon process. These letters are not grades of cleaning strength; leave the solvent choice within the applicable instruction to the cleaner.
The W symbol means professional wet cleaning. Water is part of that controlled professional process, but the W does not turn the circle into a home machine-wash or hand-wash instruction. Read the first-position washtub separately to learn whether home washing is permitted. A cleaner with the appropriate wet-cleaning process is the audience for the W.
The letter addresses the cleaner because the standard is communicating treatment limits at the point of professional care. You do not need to decode a letter into a shopping list. Point it out when you hand over the garment and keep the care label attached.
A cross over the circle is a specific prohibition
The do-not-dryclean symbol places a large cross over the circle. It forbids professional dry cleaning. Do not read it as a crossed drying square, and do not infer a home washing method from it. Move back to the washtub and the garment's other symbols to see which care routes are actually permitted.
A crossed professional circle and a W circle answer different questions. The crossed dry-cleaning mark closes the dry-cleaning route. The W mark positively identifies professional wet cleaning. Only follow a professional wet-cleaning route when the label actually provides that instruction; do not invent it as the automatic substitute for a dry-cleaning prohibition.
The size of the cross matters when the tag is crowded. It runs across the circle itself. A letter remains contained inside an uncrossed circle. Nearby strokes from another symbol or a fabric-content line are not part of the professional mark unless they touch its circle in the printed care row.
Standard and edition affect the letter set
ISO 3758 and ASTM D5489 share the stand-alone circle family, but exact letters and process definitions depend on the standard and edition. ASTM D5489-18 includes professional wet-cleaning symbols; the FTC-recognized D5489-96c edition does not. A plain circle permits dry cleaning in both systems, and the circle's marks require no washing dot-to-number conversion.
A label can still look unfamiliar because regional layouts and nearby wording vary. Use the family order and outside shape first, then read the letter or cross. The US and international comparison covers the families with larger visible differences, while the final circle position gives you a stable reference point for professional care.
Common professional care mix-ups
Check the shape and the placement of each mark before acting on a small or faded label.
A circle mistaken for tumble drying
Trace around it. A circle inside a square belongs to drying. A circle standing alone belongs to professional care.
A letter treated as a home instruction
P, F, and W address the professional cleaner. They do not name a home solvent, detergent, or washer setting for you to choose.
P read as perc only
P is the professional P-process mark and allows the solvent options covered by that process. F is the narrower petroleum-based solvent mark.
W read as ordinary water washing
The W stays inside a professional-care circle. It means professional wet cleaning, not hand washing or a cycle in your own machine.

Questions about professional care symbols
- What should I do when I see a letter inside a circle?
- Take the garment to a professional cleaner and show them the whole label. The letter tells the cleaner which professional process is permitted.
- Does P mean the garment must be cleaned with perc?
- No. P permits professional solvent classes rather than requiring perc alone. Under ISO 3758 and ASTM D5489-18, those classes include perchloroethylene and hydrocarbons; ASTM D5489-96c defines P as any solvent except trichloroethylene. The cleaner follows the instruction for the applicable standard and edition.
- Does W mean I can wash the item at home?
- No. W inside a circle means professional wet cleaning. Read the washtub at the start of the label for any home-washing permission.
- Can I wash an item that says do not dry clean?
- The crossed circle only settles the dry-cleaning question. Follow the separate washing symbol to see whether machine washing, hand washing, or no washing in water is permitted.
