I know .. I know it doesnt necessarily make sense to clean a dishwasher thats cleans. A dishwasher takes in food particles and minerals can build up in and around your dishwasher. Which this will prevent it from cleaning thoroughly and we all want to long the life of our dishwashers. Especially during a time like now we want it to work properly and kill all germs inside. Your dishes will be cleaner and your dishwasher will run more efficiently. I suggest cleaning the dishwasher every 3 months with vinegar or a good all purpose cleaner that kills germs.
I love cleaning around all door seals, inside door, remove trays and wipe all interior walls down. The bottom I like to wipe down and remove any food trap/ filter that are removable ( some people dont realize there is a food trap down there). If your dishwasher always smells this may be the cause. Once I remove the trap/filter I scrub it with a toothbrush. Afterwards I place everything back in the bottom of the dishwasher. Then I place a cup of vinegar in the bottom of the dishwasher, close the door and perform a quick, hot santized wash. Any of the mineral build up is washed away.
Cleaning the dishwasher will take about 5 minutes of hands on cleaning. Try this QUICK and EASY method every 3 months.
