To wash: Machine wash, preferably in a high capacity, front loading machine or agitatorless top loading, using a regular amount of pre-mixed detergent. If soap-sensitive, rinse twice. Use warm or cold water to maintain colour brightness.
If the blanket does not fit easily into the tub of your machine, it should be cleaned at a laundromat in a high capacity machine.
Do not use bleach or excessively hot water.
To dry: Tumble dry in dryer. The blanket will form a ball when in the dryer, reducing the likelihood of drying. Several times during the drying cycle, take blanket out, shake and replace in dryer. If possible, even after it feels dry to touch, allow to air dry over a railing or chairs to ensure complete drying.
