Can Dishwasher Tablets Remove Odors? Here’s What You Need to Know
For many families, the dishwasher is a household hero. It saves time, effort, and keeps the kitchen organized. But what happens when your dishwasher starts to smell? That sour, musty odor can quickly become unpleasant—and may even transfer to your dishes.
More people are turning to dishwasher effervescent tablets (sometimes called dishwasher cleaning tablets or machine cleaner tabs) as an effective solution. But do dishwasher tablets actually remove odors, or is this just a marketing gimmick?
In this article, we’ll explore how dishwasher tablets work, whether they truly tackle bad smells, and how to get the most out of them. If you’re seeking a cleaner, fresher kitchen environment, this is for you.
What Causes Dishwasher Odors?
Before diving into how cleaning tablets work, it’s important to understand why dishwashers develop unpleasant smells:
-
Trapped food particles: Even the best dishwashers may leave behind tiny bits of food that rot over time.
-
Grease buildup: Oils and fats can coat internal components, providing a breeding ground for bacteria.
-
Moisture and humidity: Dishwashers are damp environments, which promote mold and mildew growth.
-
Clogged filters and spray arms: These can harbor food gunk and sludge that leads to bad odors.
Simply running your dishwasher regularly may not be enough. That’s where cleaning tablets come in.
How Do Dishwasher Effervescent Tablets Work?
Dishwasher cleaning tablets are specially formulated with powerful cleaning agents that break down residue, limescale, and grease inside the dishwasher. They usually contain:
-
Sodium bicarbonate (baking soda): Neutralizes odors.
-
Citric acid: Dissolves mineral buildup and soap scum.
-
Surfactants: Break down grease and stuck-on food.
-
Effervescent agents: Help distribute cleaning power evenly during the cycle.
When placed inside your empty dishwasher and run on a hot cycle, these ingredients reach places normal dishwashing detergent cannot, including filters, spray arms, and hidden corners.
Do Dishwasher Cleaning Tablets Really Remove Odors?
Yes—if used correctly. While results may vary depending on your dishwasher’s condition, most high-quality dishwasher cleaning tablets are designed to:
-
Eliminate odor-causing bacteria
-
Remove built-up grease and food residue
-
Freshen the interior with a neutral or light citrus scent
The key is consistency. Using these tablets once a month can prevent odor from developing in the first place. If your dishwasher already smells bad, a couple of back-to-back cleaning cycles may be required to reset it.
Additional Benefits of Dishwasher Tablets
Besides tackling bad smells, dishwasher tablets offer a range of benefits that support long-term dishwasher health:
| Benefit | How It Helps |
|---|---|
| Removes limescale | Improves dishwasher efficiency and longevity |
| Cleans hidden parts | Keeps spray arms, filters, and hoses clear |
| Saves time | One-step cleaning with no disassembly required |
| Eco-friendly options | Many formulas are biodegradable and safe for septic systems |
How to Use Dishwasher Cleaning Tablets (Step-by-Step)
Using a dishwasher cleaning tablet is simple. Here’s a quick guide:
-
Empty the dishwasher completely. No dishes or utensils should be inside.
-
Place the tablet in the detergent dispenser or directly on the bottom of the dishwasher (check product instructions).
-
Run a full hot cycle—ideally the longest, hottest setting available.
-
Leave the door open after the cycle to help the interior dry and prevent moisture buildup.
-
Repeat monthly for best results.
Pro Tip: Some brands offer tablets specifically designed for both dish and washing machine cleaning. Double-check the packaging before use.
Other Tips to Keep Your Dishwasher Odor-Free
While cleaning tablets do a great job, it’s best to combine them with good dishwasher hygiene practices:
-
Scrape food before loading (but no need to pre-rinse).
-
Clean the filter manually every 2–4 weeks.
-
Run hot cycles at least once a week to prevent buildup.
-
Leave the door slightly ajar between uses to prevent mold.
-
Use vinegar rinse occasionally for an extra cleaning boost.
What to Look for When Choosing a Cleaning Tablet
Not all dishwasher tablets are created equal. Look for products that meet the following criteria:
✅ Citrus or baking soda base for odor control
✅ No harsh chemicals—especially if you have children or pets
✅ Safe for septic systems and eco-friendly
✅ Brand reputation—read reviews from other users
If you prefer natural alternatives, consider DIY dishwasher cleaners using baking soda, vinegar, and essential oils. However, store-bought tablets offer stronger cleaning for heavy-duty needs.
Final Thoughts: A Fresh Start for Your Dishwasher
To sum it up:
Yes, dishwasher cleaning tablets can effectively remove odors, especially when used regularly and combined with smart cleaning habits.
For busy households, a simple monthly clean with a quality effervescent tablet can make a big difference. Not only will your dishwasher smell fresher, but your dishes will also be cleaner—and your appliance will last longer.
So next time your kitchen doesn’t smell quite right, the solution might be just one tablet away.
