How to Clean the Bottom of Your Dishwasher

Have you ever wondered why your dishes aren’t as sparkling clean as they used to be? It might not be your detergent’s fault – your dishwasher might need a little TLC. In this guide, we’ll delve into the often-overlooked area – the bottom of your dishwasher – and explore the secrets to keeping it clean for optimal performance.

How to Clean the Bottom of Your Dishwasher?

Cleaning the bottom of your dishwasher is an important task to ensure that it functions efficiently and effectively. The first step is to remove the bottom rack and inspect the drain area for any food scraps, debris, or hard water deposits. Use a toothbrush or a small brush to scrub away any buildup, and then use a mixture of vinegar and baking soda to clean and deodorize the area. Run a hot water cycle with a cup of vinegar to further eliminate any remaining residue.

Additionally, it’s essential to regularly check and clean the filter located at the bottom of the dishwasher. Remove the filter and rinse it under running water to dislodge any trapped food particles or grime. For stubborn stains or odors, consider using a commercial dishwasher cleaner according to the manufacturer’s instructions. By following these steps, you can maintain a clean and well-functioning dishwasher for years to come.

Understanding the Need for Cleaning
