I have cheap pillows, but a brand new washer with a bedding setting. I wash pillows a LOT because of puppies mostly... bleach is fine with cheap pillows and just make sure the setting used is a low or slow spin or the machine will get angry.
Here you go.
Skip harsh chemicals like bleach if you can. Use hydrogen peroxide instead. Vinegar in the rinse works well too.
Hi . You can wash them in the washing machine on a lower or perm press setting . Add vinegar and baking soda to the detergent for an extra fresh clean .
