Learn how to deeply clean your dishwasher using tablet refills. This step-by-step tutorial covers pre-rinse, cleaning the filter, running a tablet cycle, and maintenance tips for a sparkling machine.
Your dishwasher works hard every day, cleaning plates, glasses, and utensils so you don’t have to. But over time, grease, food particles, and hard water minerals build up inside the machine, leading to odors, poor cleaning performance, and even clogs. A deep clean is essential—and using tablet refills is one of the most effective ways to restore your dishwasher’s performance without harsh chemicals or single-use plastic. In this tutorial, we’ll walk you through a thorough dishwasher cleaning routine using tablet refills, keeping your appliance fresh and efficient.
Why Deep Clean Your Dishwasher?
A neglected dishwasher can develop a film of residue that traps bacteria and causes musty smells. Hard water deposits can clog spray arms and the filter, reducing water pressure and leaving dishes spotty. Regular deep cleaning not only extends the life of your machine but also ensures your dishes come out truly clean. Using tablet refills offers a convenient, eco-friendly solution: they dissolve completely, leave no plastic waste, and are free from phosphates and chlorine bleach.
What You’ll Need
Before you start, gather these items:
- A high-quality dishwasher cleaner tablet (we recommend the Dishwasher Detergent & Toilet Bowl Cleaner Duo for a dual-purpose clean)
- White vinegar (optional, for extra deodorizing)
- A soft brush or old toothbrush
- A microfiber cloth
- Baking soda (for stubborn stains)
Step 1: Pre-Rinse and Remove Debris
Start by removing all dishes, racks, and silverware baskets from the dishwasher. Check the bottom of the machine for large food particles or broken glass. Use a damp cloth to wipe away any loose debris from the door gasket and edges. This step ensures that the tablet refill can work directly on the interior surfaces.
If you have a Pop-Up Sponge, it’s perfect for wiping down the gasket and corners—just be sure to rinse it thoroughly afterward.
Step 2: Clean the Filter
The filter is often the dirtiest part of a dishwasher. Locate it at the bottom of the tub (usually under the bottom rack). Twist or lift it out, then rinse under hot water. Use a soft brush to scrub away any trapped food or grease. For a deeper clean, soak the filter in a mixture of warm water and a few drops of dish soap. Rinse thoroughly and replace it. A clean filter improves water flow and prevents odors.
Step 3: Run a Hot Cycle with a Tablet Refill
Place one tablet refill in the main detergent compartment (or directly on the bottom of the tub if your cycle recommends it). Close the door and select the hottest, longest cycle available—usually the “Heavy” or “Sanitize” option. The heat activates the tablet, dissolving grease and mineral deposits. If your dishwasher has a self-clean cycle, use that instead.
For best results, we suggest using the 1 Year of Dishwasher Detergent refills: they are concentrated, plastic-free, and formulated to tackle tough buildup.
Step 4: Wipe Down Interior Surfaces
After the cycle finishes, open the door and wipe down the interior walls, door gasket, and the bottom of the tub with a microfiber cloth. You may notice a bit of residue—this is normal. Use a cloth dampened with white vinegar to remove any remaining film. Pay special attention to the spray arms: if the holes are clogged, use a toothpick or brush to clear them.
Step 5: Deodorize and Polish (Optional)
If your dishwasher still has a lingering smell, sprinkle a cup of baking soda across the bottom of the tub and run a short hot cycle. This neutralizes odors naturally. For a sparkling finish, you can also run a cycle with a cup of white vinegar placed in a dishwasher-safe bowl on the top rack (never mix vinegar with bleach or other cleaners).
How Often Should You Deep Clean?
For most households, a deep clean every 3–4 months is sufficient. If you have hard water or run multiple loads daily, consider doing it every 2 months. In between deep cleans, you can maintain freshness by running a monthly hot cycle with a tablet refill.
Benefits of Using Tablet Refills for Dishwasher Cleaning
| Feature | Traditional Liquid/Pod Cleaners | Tablet Refills (e.g., Bluelandoutlet) |
|---|---|---|
| Plastic packaging | Often single-use plastic | None—tablets packaged in paper or compostable wrappers |
| Chemical load | Often contains chlorine bleach, phosphates | Free from harsh chemicals, biodegradable |
| Cost per use | Varies, often higher | Lower long-term cost with refill subscriptions |
| Effectiveness on buildup | Good, but may leave residue | Excellent with hot water activation |
Switching to tablet refills not only deep cleans your dishwasher but also reduces your household’s plastic waste—a win for your appliance and the planet.
Common Mistakes to Avoid
- Overloading the dishwasher before a deep clean—always run the cycle empty for best results.
- Skipping the filter cleaning—a dirty filter undermines the tablet’s performance.
- Using too many tablets—one tablet per cycle is enough; more can cause oversudsing.
- Ignoring the door gasket—mold and mildew love this area; wipe it regularly.
Maintenance Tips for a Longer-Lasting Dishwasher
To keep your dishwasher running smoothly between deep cleans:
- Scrape food off plates before loading (no need to rinse).
- Run hot water in the sink before starting the dishwasher—this ensures the first wash is hot.
- Leave the door cracked open after a cycle to let moisture escape.
- Use a Hand Soap Duo set for hand-washing delicate items—it reduces the load on your dishwasher and keeps your hands soft.

Deep cleaning your dishwasher with tablet refills is simple, effective, and eco-friendly. By following these steps—pre-rinse, clean filter, run a hot cycle, wipe down, and deodorize—you can restore your machine’s performance and keep dishes sparkling.
