Begin by filling a washing machine or bathtub with hot water. The water should be very hot for the solution to work effectively.
Add the laundry detergent, powdered dishwasher detergent, bleach, and borax to the hot water. Stir well to combine all the ingredients.
Place the yellowed pillows into the mixture, ensuring they are fully submerged. Let them soak for about 30 minutes, flipping them halfway through for thorough cleaning on both sides.
After soaking, place the pillows in the washing machine. Run a complete cycle with hot water and an extra rinse if possible.
Once the washing cycle is complete, dry the pillows thoroughly in a dryer set to a high-heat setting. It’s essential to ensure they are completely dry to prevent mold growth.
