If you own a dishwasher, you already know it saves a lot of time and effort in the kitchen. However, many people forget that the dishwasher itself needs cleaning too. Over time, grease, food particles, and limescale build up inside, causing bad smells, cloudy dishes, and even machine breakdown. That’s where Finish Dishwasher Cleaner Tablet comes in—a product designed to clean the parts of your dishwasher you can’t see. Using it is simple, but there are important details to get the best results and keep your dishwasher running smoothly.
This guide will show you exactly how to use Finish Dishwasher Cleaner Tablet, why it matters, and how you can avoid common mistakes. Whether you’re new to dishwashers or want to extend the life of your machine, you’ll find practical advice and clear instructions here.
What Is Finish Dishwasher Cleaner Tablet?
The Finish Dishwasher Cleaner Tablet is a specially made cleaning product for dishwashers. Unlike regular dish soap, this tablet is not for washing your dishes—it’s designed to clean the inside of the dishwasher itself. The tablet works by releasing powerful cleaning agents during the wash cycle. These agents break down limescale, grease, and food residue from hidden parts like the spray arms, filter, and pipes.
There are two main types: single-use tablets and multi-use packs. Both kinds do the same job, but the multi-use pack gives you more tablets for regular cleaning.
Key Ingredients
Finish Dishwasher Cleaner Tablets usually contain:
- Citric acid: Breaks down limescale and hard water deposits.
- Surfactants: Remove grease and fats.
- Sodium carbonate: Helps soften water and boost cleaning power.
These ingredients are safe for dishwashers and won’t harm the machine’s metal or plastic parts.
How It Differs From Regular Detergent
Some people think regular dishwasher detergent will clean the machine. But dishwasher detergent is made to clean dishes, not the dishwasher itself. It doesn’t reach or dissolve the grime stuck in the pipes, spray arms, or hidden corners. The Finish Dishwasher Cleaner Tablet’s formula is stronger and targets the places you can’t see or reach.
Why Clean Your Dishwasher Regularly?
It’s easy to assume your dishwasher stays clean because it washes dishes every day. However, grease, soap scum, and food particles still build up inside the machine. If you ignore cleaning, you might notice:
- Bad odors: Trapped food and grease start to smell.
- Cloudy glassware: Limescale and residue make clean dishes look dirty.
- Poor cleaning results: Dishes come out with bits of food or water spots.
- Shorter machine life: Build-up can clog parts and strain the motor.
According to the National Sanitation Foundation (NSF), dishwashers can harbor bacteria like E. coli and salmonella if not cleaned regularly. Using a cleaner like Finish can reduce these risks and keep your appliance safe and efficient.
How Often Should You Clean?
- Monthly: For most homes, using the cleaner once a month is enough.
- Heavy use: If you run your dishwasher daily or have hard water, clean every 2-3 weeks.
- After repairs or maintenance: Always clean the dishwasher after fixing leaks or replacing parts.
How To Prepare Before Using Finish Dishwasher Cleaner Tablet
Before you use the tablet, a little preparation helps the cleaning work better. These steps take just a few minutes and make a big difference.
1. Empty The Dishwasher
Remove all dishes, utensils, and racks if possible. The tablet is designed for an empty dishwasher. If you leave dishes inside, the cleaner might leave a strong smell or taste on them.
2. Check The Filter
The filter at the bottom of the dishwasher collects food particles. Take it out and rinse it under hot water. If it’s greasy or clogged, scrub with a soft brush. This step stops large debris from blocking water flow during cleaning.
3. Wipe The Door And Seals
Food and grease can collect around the door seal. Wipe it with a damp cloth. Pay special attention to the edges and corners where mold or grime can hide. Doing this first means the tablet can focus on the inside, not just the door.
4. Inspect The Spray Arms
Check the spray arms for any blocked holes. If you see any, use a toothpick or soft brush to clear them. This helps water flow freely during the cleaning cycle.
5. Read The Instructions
Every dishwasher is a bit different. Take a moment to read both your dishwasher manual and the instructions on the Finish Tablet package. Some dishwashers have a special cleaning cycle; others do not.
Step-by-step Guide: How To Use Finish Dishwasher Cleaner Tablet
Now you’re ready to clean your machine. Follow these simple steps to get the best results.
Step 1: Place The Tablet
- Take one Finish Dishwasher Cleaner Tablet out of the packaging.
- Do not unwrap the tablet if it comes in a dissolvable film.
- Place the tablet flat on the bottom of the empty dishwasher. Do not put it in the detergent dispenser—this is a common mistake.
- Placing it on the bottom lets the tablet dissolve at the right time and spread the cleaning agents everywhere.
Step 2: Choose The Right Cycle
- Select the hottest wash cycle available. Most dishwashers have a “Heavy,” “Intensive,” or “Sanitize” option.
- Using a hot cycle helps the tablet dissolve fully and activates all the cleaning ingredients.
- Do not use quick or eco cycles for cleaning.
Step 3: Start The Dishwasher
- Close the door and start the cycle.
- Let the dishwasher run through the entire cycle without interruption.
Step 4: Wait And Air Out
- When the cycle finishes, open the door and let the dishwasher air out for 15-30 minutes.
- This helps remove any strong smells and lets the inside dry completely.
Step 5: Wipe Down If Needed
- After cleaning, check the inside for any loose debris.
- Wipe the bottom and door seal again if you see leftover grime.
Quick Reference Table
Here’s a summary of the steps for easy review:
| Step | Action | Why It Matters |
|---|---|---|
| 1 | Place tablet on bottom | Ensures full dissolving and coverage |
| 2 | Select hottest cycle | Activates cleaning agents |
| 3 | Run cycle empty | Prevents smell or residue on dishes |
| 4 | Air out after cycle | Removes smells, dries interior |
| 5 | Wipe any debris | Finishes the cleaning process |
Tips For Best Results
To keep your dishwasher in top shape, try these extra tips:
- Use the cleaner regularly: Don’t wait for bad smells. Monthly cleaning keeps buildup away.
- Check for hard water: If you see white spots on glassware, your water may be hard. Clean more often and consider a water softener.
- Don’t skip the filter: A clogged filter reduces cleaning power and makes the machine work harder.
- Run hot water before starting: Run your kitchen tap until the water is hot before starting the dishwasher. This ensures the cycle begins with hot water, improving cleaning.
- Don’t mix with bleach: Some people use bleach for cleaning. Never mix it with Finish Cleaner, as this can release dangerous fumes.
Common Mistakes To Avoid
Even with clear instructions, some mistakes can reduce the cleaner’s effectiveness or even damage your machine.
Putting The Tablet In The Detergent Dispenser
The cleaner tablet must be placed at the bottom of the dishwasher. If you put it in the detergent cup, it may not dissolve properly or release at the right time.
Running With Dishes Inside
Always clean with an empty dishwasher. The cleaner is too strong for dishes and can leave a chemical taste or smell.
Using The Wrong Cycle
A cold or short cycle won’t dissolve the tablet fully. Always use the hottest, longest cycle.
Skipping Pre-cleaning Steps
If you don’t clean the filter or wipe the seals, the cleaner can’t do its job properly. Big pieces of food or grease block water flow and reduce cleaning power.
Overusing The Cleaner
More is not better. Using multiple tablets at once can damage rubber parts or over-sud the machine. Stick to one tablet per cleaning.
What If You Don’t Have A Special Cleaning Cycle?
Some modern dishwashers have a “Machine Care” or “Self-Clean” button. If yours does, use it with the Finish Tablet. If not, just select the hottest normal wash cycle—this works just as well. The cleaning tablet is designed to work in any dishwasher, old or new.
How Finish Dishwasher Cleaner Compares To Other Cleaning Methods
You may wonder if you can clean your dishwasher with home remedies like vinegar or baking soda. Let’s compare:
| Cleaning Method | Pros | Cons |
|---|---|---|
| Finish Dishwasher Cleaner Tablet | Easy to use, strong cleaning power, safe for all parts | Costs more than homemade solutions |
| White Vinegar | Cheap, removes some limescale | Can damage rubber seals if used too often |
| Baking Soda | Deodorizes, mild abrasive | Doesn’t remove limescale or grease well |
| Bleach | Kills bacteria | Corrosive, not safe for stainless steel or rubber parts |
The Finish Tablet is designed for deep cleaning without harming your dishwasher. It’s tested by manufacturers and safe for all materials inside your machine.
Real-world Example: Cleaning In A Hard Water Area
Suppose you live in an area with hard water. Hard water leaves white spots on dishes and builds up inside the dishwasher fast. If you use the Finish Dishwasher Cleaner Tablet every three weeks, you’ll notice:
- Fewer white spots on glassware
- Less limescale in the spray arms
- No strange smells after running cycles
Some users report that after just one use, their dishwasher smells fresher and runs quieter. But the real difference shows after regular cleaning over several months—your dishes will look cleaner, and the machine will need fewer repairs.
The Environmental Impact
Finish Dishwasher Cleaner Tablets are designed to be eco-friendly when used as directed. The cleaning agents break down safely, and the packaging is recyclable in many areas. Using a cleaner also extends the life of your dishwasher, reducing electronic waste.
However, don’t use the cleaner more often than needed. Overuse won’t help and adds unnecessary chemicals to the water system. Follow the recommended cleaning schedule.
How To Store Finish Dishwasher Cleaner Tablets
Proper storage keeps your tablets effective:
- Keep in a cool, dry place: Humidity can make tablets stick together or dissolve early.
- Close the box tightly: This keeps air and moisture out.
- Keep away from children and pets: The tablets are not food and should not be handled by kids.
- Avoid storing near heat: High temperatures can break down the ingredients.
If the tablet gets soft or broken, it may not work as well. Always use a whole, solid tablet for best results.
When To Replace Your Dishwasher Cleaner
Each Finish Tablet is for one use only. If you notice the following, it’s time to use a cleaner again:
- Dishwasher smells musty or sour
- Dishes come out with food bits or streaks
- Visible limescale inside the machine
- Your area has very hard water
If you clean monthly but still see problems, increase cleaning frequency or check for other issues like blocked spray arms or a broken filter.

Troubleshooting: If You Don’t See Results
Sometimes, even after cleaning, your dishwasher may still smell or perform poorly. Here’s what to do:
- Check for blockages: Make sure nothing is blocking the spray arms or filter.
- Use a second cleaning: If the dishwasher has never been cleaned, do a second cleaning cycle a week later.
- Check water temperature: If your water heater is set too low (below 120°F/49°C), the tablet may not dissolve fully.
- Inspect the drain hose: A kinked or blocked drain hose can trap dirty water inside.
- Contact support: If problems persist, contact your dishwasher manufacturer.
Is Finish Dishwasher Cleaner Safe For All Dishwashers?
Yes, the cleaner is tested for use in all common brands, including Bosch, Whirlpool, Samsung, LG, and more. It’s safe for both stainless steel and plastic interiors. If you have a very old or special dishwasher, check the manual or the Finish website for guidance.
