How to Get Rid of Smell in Dishwasher Drain

Tools:

- E-Cloth
- White vinegar
- Baking soda
- Lemon (slices or juice)
- Warm water

Clean the Filter

Remove the dishwasher filter and rinse it thoroughly to eliminate built-up food particles and grease.
Use warm water to wash it carefully, ensuring no residue or debris is left behind.

Clear Out the Drain Area

Inspect the drain area for any hidden bits of food or buildup and remove them manually.
Wipe the interior surfaces around the drain with a damp cloth to clear away any lingering debris.

Run a Vinegar Rinse Cycle

Place one cup of white vinegar in the bottom of your dishwasher or in a dishwasher-safe container on the top rack.
Start a hot water cycle to help break down grease and neutralize unpleasant odors.

Use Baking Soda for Extra Freshness

After the vinegar cycle, sprinkle one cup of baking soda evenly on the bottom.
Run a short, hot cycle to activate its deodorizing properties and boost freshness.

Add a Citrus Boost (Optional)

If you prefer a zesty scent, place a few lemon slices or drizzle a small amount of lemon juice inside before running a final rinse cycle.
This step infuses a natural, clean aroma without overwhelming your senses.

Safety Precautions

Unplug or turn off power to the dishwasher before removing the filter or cleaning near electrical components to avoid electric shock.
Wear rubber gloves to protect your hands from sharp debris, hot water, and cleaning agents.
Allow the dishwasher to cool completely after use before starting any cleaning to prevent burns.
Use only food-safe cleaning agents like vinegar and baking soda; avoid harsh chemicals that can damage the appliance or leave harmful residues.
Handle glass or ceramic containers with care during the vinegar rinse to prevent breakage and injury.
Ensure proper ventilation in the kitchen when using vinegar or lemon to avoid inhaling strong fumes.

Common Mistakes When Cleaning How to Get Rid of Smell in Dishwasher Drain

Not Decluttering Before Cleaning

Clear the clutter: Before you start scrubbing, take a few minutes to tidy up. Without clutter, surfaces are easier to clean and you won't miss dirty spots hidden behind random junk.
Simplify your process: Removing excess items not only speeds up cleaning but also reduces stress by creating a more open, manageable space.
Boost efficiency: A clear area means you’re not just shuffling chaos around. You’ll have a better overview, making it easier to spot where the mess really is.

Using the Wrong Cleaning Products

Know your surfaces: Different materials need different care. For example, granite counters require pH-neutral cleaners while tile floors often do better with a slightly acidic solution.
Avoid harmful mixtures: Mixing cleaning agents can create toxic fumes. Stick with one product per surface and follow manufacturer guidelines.
Invest in multi-surface cleaners: When in doubt, a good multi-surface cleaner can handle daily dirt without the risk of damaging your favorites.

Neglecting Often-Forgotten Areas

Mind the nooks: Areas like baseboards, behind appliances, and ceiling fan blades easily gather dust but are often neglected. A focused effort on these spots brings a noticeable difference.
Don't skip the corners: They hide grime—so, use tools like an extendable duster or a microfiber cloth to reach the tough-to-clean areas.
Regular touch-ups: Incorporate these into your routine cleaning schedule. A little extra effort now saves you a major overhaul later.

How Often to Clean How to Get Rid of Smell in Dishwasher Drain

Recommended Frequency for Cleaning the Dishwasher Drain

Monthly Cleaning: If you use your dishwasher frequently or have a busy household, cleaning the drain once a month is ideal. This schedule prevents the buildup of food particles, grease, and soap scum that can trap odors.
Every Two Months: For households with lighter dishwasher use, cleaning the drain every two months should be sufficient. Less frequent use means fewer residues accumulate, reducing the risk of persistent smells.
Why This Frequency: Over time, residual food and detergent can clog the drain, leading to stagnant water and a musty smell. Regular cleaning—whether monthly or bi-monthly—ensures that the drain remains clear, water flows properly, and odors are kept at bay.
Proactive Prevention: Keeping to this cleaning schedule also minimizes the risk of bacterial growth and unpleasant foul-smells, making your dishwasher and kitchen environment healthier and fresher.
