How to Clean Dishwasher without Using Chemicals

This appliance thoroughly cleans kitchen utensils, saving us time and money; however, if you notice that the dishes do not come out clean or there is a disgusting smell inside, Your dishwasher needs an urgent cleaning!

We will use baking soda and white vinegar for this task, an economical and ecological solution.

From time to time, it is necessary to carry out deep cleaning of this appliance. The reasons? On the one hand, the appliance’s filter accumulates the remains of the food, so it is susceptible to generating bad odors, mold, and blockages.

On the other hand, it should be borne in mind that the lime and the impurity of the water cause the appliance to deteriorate and function incorrectly.

For this reason, it is advisable to remove as much as possible the remains of food adhering to a utensil (for example, with kitchen paper) and clean this appliance at least once a month. And this is where products such as white vinegar or baking soda come into play.

How to clean the dishwasher inside

1. Filter cleaning

To make this appliance shine, the first thing you should clean is the appliance’s filter. It is a small, elongated basket located in the lower part, just below the blades.

If you notice a foul odor when unscrewing the dishwasher filter, you need to soak it for 30 minutes in a bucket with 2 cups of hot water, 2 cups of white vinegar, and a splash of soap.

After the soak time, you need to remove all the dirt with the help of an old toothbrush you no longer use. If the filter is dirty or has never been cleaned, you can soak it in hot water for 15-20 minutes. Afterward, add soap and a pinch of baking soda. Be careful not to break any of the items you are handling.

When you finish cleaning the filter, please put it back in the dishwasher. The next step will be creating a homemade solution that effectively cleans the entire appliance.
