Unlike other sweaters and winter wear, you can easily wash the fleece ones. If you are looking out for a quick and easy option, then opt for a machine wash. Fling your fleece sweaters into your washing machine and wash them. Make sure that the machine setting is kept to winter wash, which is usually gentle washing. You can just simply set the wash for the minimum time that is possible and take it out for air drying. If you have time, hand washing is possible and possibly a better way to ensure a longer lifespan of your outfit. Remember always use powered detergent than liquid and avoid hot wash since it damages the fleece.
