Here is the next set of pillows and again they had been washed and dried before. I placed the pillows in the wash and added a mixture of 1 cup laundry detergent, 1 cup washing soda, 1 cup Borax, and 1 cup Castile soap. Soaked 30 minutes, flipped the pillows and soaked another 30 minutes, ran the wash cycle and here is how they came out…
Definitely made a difference but one pillow was still more yellow than I liked
In the end, these are great alternatives to bleach if you want to stay away from chemicals. It works on pillows, pillow covers, and mattress pads
