Identify the crossed tumble-dryer mark, compare it with natural-drying symbols, and follow the rest of the garment label.
What the symbol means
A square containing a circle means tumble drying. When that combined mark is crossed out, keep the item out of a tumble dryer. The prohibition does not, by itself, tell you which natural-drying method to use.
What to do
Do not put the item in a tumble dryer, including an unheated tumble cycle.
Check the same label for a separate square containing horizontal or vertical lines. That mark gives the permitted natural-drying method.
If no drying method is shown, keep the item out of the dryer and follow any written manufacturer instructions instead of guessing.
Do not confuse these drying marks
Use the whole mark, not only its outside shape.
Do not tumble dry
Crossed square-and-circle: no tumble drying.
Tumble dry
Square-and-circle without a cross: tumble drying is allowed; dots and bars set heat or cycle limits.
dry flat
Horizontal line in a square: lay the item flat to dry. This is a separate natural-drying instruction.
Put it into practice
Flat drying and line drying are different instructions. “Do not tumble dry” alone does not tell you which one to choose.
1
Separate it before loading the dryer
Keep items with a crossed square-and-circle out of the dryer load. A low-heat, air-fluff or delicate setting does not cancel this instruction.
2
Find the actual drying method
Read the other drying mark or written directions. Flat, line and drip drying are different methods; use the one specified for this item.
3
Keep every modifier attached
If the label also says “in shade,” use a place out of direct sun. If it says “drip,” follow that instruction rather than adding an extra spin to hurry drying.
Match the rest of your label
Use this as a reading aid and follow the complete garment label, including any written instructions.
