Water with high iron content can easily stain the inside of your dishwasher. However, it is easy to get it looking sparkling again. Fill the soap dispenser of your empty dishwasher with powdered citrus drink mix. Begin the wash cycle, stopping it midway and leave the door cracked open for about an hour. Complete the cycle, and you’ll have a super-clean washer again.
