If your washing machine can handle it, wash two pillows at a time to keep the washer balanced. On a gentle cycle with warm water, use just a little bit of mild laundry detergent (1 tbsp will do). Make sure to add an extra rinse cycle so there is no leftover sticky residue from the detergent.
To hand wash your pillows, fill a tub with warm water. Mix in a small amount of mild laundry detergent (about 1tbsp). Place your pillows in and gently squeeze them to get work in the soap and water. Repeat this until you are satisfied with the saturation and thoroughness. To rinse, we recommend running the pillows under running water, or refilling the tub with clean water. To rinse, gently squeeze the pillow to rid of the soap. Avoid wringing the pillow out, as it can damage the shape of it.
To spot clean first vaccum both sides of the pillow to remove any dust buildup in there. To tackle and soiled areas, use a cloth dipped in mild sudsy water and dap to remove the stains. Using a clean damp cloth, dap at the area so no soapy residue remains. Air dry before replacing them back on the bed.
