How to clean pillows to kill bacteria and mites?

The first is about the cleaning of pillowcases, because pillowcases are relatively covered outside, which is easy to get dirty. Take off the pillowcase, put it in warm water, pour an appropriate amount of white vinegar in warm water, soak it for 20 minutes and then clean it, so that the pillowcase will look extra clean after cleaning. The most important thing is actually about the cleaning of the pillow core, because it is more particular than the cleaning of the pillowcase. It is suggested to soak the pillow core in warm water for 15 minutes, then wash it by machine, and add some bleach and borax. Note that pillows should be placed along the drum of the washing machine, and should not be stacked together to avoid cleaning.
