Cleaning a white hat in a washing machine is one of the easiest ways to clean it. The only downside to this is that you won’t get out as much of the stains as if you had used your hands.


Step 1- Preparing The Hat


* Because you will be doing less work with your hands, all you need to do is spray some diluted bleach over the entire hat. The reason for diluting the bleach is to prevent it from bleaching the white hat too much and giving it a yellow stain.


* Place the hat in the washing machine and put the machine on the quick wash setting. Let the machine do its work and then place it in the dryer when done.
