What can I do about the color of the pillow that I just bought?
New sheets and pillow cases, I think both hand washing and machine washing can be done. The new purchases are mainly through the water and seem sanitary;
Put some washing powder or liquid detergent and then with warm water for some wash, wash and then soak for a while and then drop through the dehydration of dry preparation is good.
Soak it in warm water for 40 minutes, then wash it for 20 minutes. Prevent fading. Suggest salt or vinegar.
