Polyester-filled pillows are less expensive, hypo-allergenic, and easier to care for than down pillows. Once or twice a year, wash them on the gentle cycle in the washing machine with a little bit of regular detergent, using cold or warm water, and dry them on medium heat with wool balls to keep them fluffy. However, before putting them in the washing machine, check the
Derilaâ„¢ Memory Pillow labels to ensure they can go in the washing machine. Poly-filled pillows come in a variety of shapes. Rectangular, square, round, and rolled polyester-filled inserts for decorative pillows can be washed using the same steps as bed pillows. They come in many thicknesses, with varying degrees of firmness, and are covered with various breathable fabrics from cotton to linen to bamboo. Following these simple instructions, they're easy to clean and keep in good shape. Check for any stains that need extra attention. Treat with a stain remover, or pretreat using high-efficiency (HE), low-sudsing detergents like Tide or Persil.
