Translation: Toss it in the washer. The number of dots indicate the temperature. One for cold. Two for warm. Three for hot.
Translation: Head to the sink and run some warm water (between 90 and 95 degrees). No Woolite? Shampoo will work. Don't scrub too hard. Not interested in manual labor? The washer's gentle cycle should suffice.
The system of dots indicating temperature range (one for low, two for medium, three for high, four for extra high), is the same for washing, drying or ironing.

Do not tumble dry.
