*** HOW TO CLEAN YOUR DISHWASHER ***
* Place a dishwasher-safe cup filled with plain white vinegar on the top rack of the dishwasher. Using the hottest water available, run the dishwasher through a cycle – except for the cup of vinegar, the dishwasher needs to be empty.
The vinegar will help to wash away the loose, greasy grime, sanitizes, and helps remove the musty odor.
* After using the vinegar to sanitize the inside of the dishwasher, sprinkle a cupful of baking soda around the bottom of the tub and run it through a short but complete cycle using the hottest water. The baking soda will help freshen the smell of the dishwasher as well as brighten up the look of the inside of your appliance by removing stains.
* Now that the dishwasher is clean and running right………here are a few IMPORTANT tips to KEEP it that way….until the next cleaning. (A routine dishwasher cleaning is a good habit to get into. And you have to admit…now that you know how it’s done…it’s not that hard.)
*Run the garbage disposal before starting the dishwasher. The dishwasher drains into the same pipe as your sink, so that drain must be clear.
*Run a bit of hot water in your sink before running the dishwasher. You will get cleaner dishes if the water starts hot. You can collect the water you run and use it for watering plants or other purposes. Run the water until what comes out of the tap feels hot.
*Make sure your water starts hot enough. Set the thermostat on your water heater to 120F (50C). Water that is cooler than this won’t do a good job cleaning. Water that is hotter could scald.
*Run full loads to conserve water and energy, but don’t pack dishes too tightly. Dishwashers wash dishes by spraying water over them, so the water needs to be able to get to the dishes to clean them.
*If you are inclined to pre-wash your dishes before you put them in the dishwasher, consider this. Dishwasher detergent NEEDS a certain amount of grease and dirt in order to do its job. Otherwise, it actually foams up during the cycle which is not good for your dishwasher.
