Understanding the Source of the Smell

The first step in tackling your dishwasher’s unpleasant odor is to understand where the smell is coming from. This is your smell diagnosis. It’s not a pleasant job, but someone’s got to do it.

The odor causes are usually old food particles that have become trapped in the filter or the corners of the machine. Over time, they start to decay and produce a nasty smell.

Understanding the source of the smell is vital to effectively clean your dishwasher and get rid of the stench.

Gathering Your Cleaning Materials

Before you start scrubbing away the stink, you’ll need to gather some essential cleaning supplies. Your cleaning solutions choices can range from commercial dishwasher cleaners to natural, eco-friendly alternatives. If you opt for the former, ensure you choose a product specifically designed for dishwashers.

Additionally, you’ll need a soft cloth or sponge for scrubbing, a toothbrush for hard-to-reach areas, and a pair of rubber gloves to protect your hands.
