Keeping your dishwasher clean is just as important as loading it correctly. Food particles, grease, and limescale can build up inside, making your dishes less clean and even causing bad smells. Many people think their dishwasher cleans itself, but that is not true. Even the best machines need extra care. This is where Finish Dishwasher Deep Cleaner comes in. If you want your dishwasher to work well for years and keep your dishes spotless, learning how to use this cleaner is a smart move.
This guide will show you everything you need to know. You will learn step-by-step how to use Finish Dishwasher Deep Cleaner, why it works, and how it keeps your machine at its best. We will answer common questions, compare this cleaner to others, and give you tips that only experienced users know.
Whether you are a beginner or want to improve your routine, you will find all the details here.
What Is Finish Dishwasher Deep Cleaner?
Finish Dishwasher Deep Cleaner is a special liquid designed to clean the inside of your dishwasher. Unlike regular detergents, it does not wash dishes. Instead, it targets the hidden parts of your dishwasher—places you cannot see, like the spray arms, filter, and pipes.
This cleaner removes limescale, grease, and odors. Over time, these build up from hard water, leftover food, and soap. If not removed, they can cause your dishwasher to smell, leave spots on your dishes, or even break down.
The bottle is small, usually 250 ml, with a special wax plug that melts during the hot cycle. This makes sure the cleaner is released only when the water is hot enough to activate its cleaning power.
Why You Should Deep Clean Your Dishwasher
Many people do not realize that dishwashers collect dirt, grease, and limescale. Even if you use it every day, some food and minerals stick to the inside. This can lead to:
- Bad smells coming from the machine
- Cloudy glasses or dishes that do not feel clean
- Reduced cleaning power
- Breakdowns that can cost a lot to fix
According to a survey by the National Sanitation Foundation, 30% of dishwashers tested contained harmful bacteria like *E. coli* and *Salmonella*. Cleaning with a deep cleaner reduces this risk and keeps your kitchen safe.

How Finish Dishwasher Deep Cleaner Works
Finish Dishwasher Deep Cleaner uses a special formula. When you place the bottle upside down in your empty dishwasher and run a hot cycle, the wax plug melts. This releases the powerful liquid, which:
- Breaks down grease from food and soap residue
- Dissolves limescale left by hard water
- Neutralizes odors caused by bacteria and mold
Most users see results after just one use. Dishes become cleaner, and the machine smells fresh. The cleaner also reaches places you cannot scrub by hand.
When And How Often To Use Finish Dishwasher Deep Cleaner
The company recommends using it once a month. If you have hard water, a large family, or use your dishwasher daily, you might need to clean it more often.
Signs that your dishwasher needs a deep clean:
- Unpleasant smells after running a cycle
- Dishes feel gritty or look cloudy
- White spots or streaks on glassware
- Machine sounds louder than usual
Cleaning once a month is enough for most homes. If you notice problems sooner, increase the frequency.
What You Need Before You Start
Using Finish Dishwasher Deep Cleaner is simple, but you should prepare:
- An empty dishwasher: Remove all dishes, racks, and utensils.
- A bottle of Finish Dishwasher Deep Cleaner: Make sure it is sealed and not expired.
- A high-temperature program: The hottest cycle works best.
- A clean filter: Take out the filter and rinse it under hot water before using the deep cleaner.
A common mistake is to use the cleaner with dishes inside. This can waste the product and leave residue on your plates. Always clean with an empty machine.
Step-by-step Guide: How To Use Finish Dishwasher Deep Cleaner
Here’s a clear, practical process you can follow:
1. Empty The Dishwasher
Remove all dishes, cutlery, and racks if possible. This allows the cleaner to reach every corner.
2. Check And Clean The Filter
Find the filter at the bottom of your dishwasher. Twist it out and rinse under hot water to remove food bits. Put it back in place.
3. Remove The Sticker
Open the Finish Deep Cleaner bottle and peel off the sticker from the top, but do not remove the cap. The cap stays on; the wax plug inside will melt during the cycle.
4. Place The Bottle Upside Down
Put the bottle upside down in the bottom rack or the silverware basket. Make sure it is secure and will not fall over.
5. Run The Hottest, Longest Cycle
Choose the hottest wash program (usually called “Intensive” or “Heavy”). Do not use a pre-wash or quick cycle. The high heat melts the wax plug and releases the cleaning liquid.
6. Wait For The Cycle To Finish
Let the cycle finish completely. Do not open the door during cleaning.
7. Remove The Bottle
When the cycle is done and the machine is cool, take out the empty bottle and throw it away.
8. Wipe Down The Door And Seals
Take a damp cloth and wipe the inside edges, door, and rubber seals. This removes any loosened dirt.
If you follow these steps, your dishwasher will be cleaner, fresher, and work better.
What Makes Finish Dishwasher Deep Cleaner Different?
There are many dishwasher cleaners on the market, but Finish has a few unique features:
- Wax plug technology: Releases cleaner at the right temperature
- Removes both grease and limescale: Many cleaners only handle one
- Trusted brand: Finish has won awards for cleaning products
Let’s compare Finish with a few other popular brands:
| Brand | Removes Grease | Removes Limescale | Odor Neutralizer | Release Method |
|---|---|---|---|---|
| Finish | Yes | Yes | Yes | Wax plug (temperature-activated) |
| Affresh | Yes | No | Yes | Tablet (dissolves in water) |
| Somat | Yes | Yes | No | Liquid (opens on contact) |
| Glisten | No | Yes | Yes | Liquid (opens on contact) |
Finish’s unique release method means the cleaner only works when the water is hot enough. This prevents waste and improves cleaning.
Common Mistakes And How To Avoid Them
Even though the process is simple, people make a few easy-to-miss mistakes:
- Using with dishes inside: Always run the cleaner with an empty machine.
- Wrong cycle: Quick or cold washes do not melt the wax plug, so the cleaner stays inside the bottle.
- Forgetting the sticker: If you forget to remove the sticker, the cleaner cannot come out.
- Not cleaning the filter: A clogged filter blocks the cleaner from reaching all parts of the machine.
- Using too often: Overuse can waste money and is not needed. Monthly use is enough.
If you avoid these mistakes, you will get the best results from your deep clean.
Tips For Best Results
Here are some tips from experienced users and experts:
- Use before holidays: Clean your dishwasher before big events, like family dinners, so dishes come out spotless.
- Pair with regular cleaning: Wipe down the door and seals weekly to prevent mold.
- Check your water: If you have hard water, use a cleaner more often or install a water softener.
- Keep the spray arms clear: Remove and rinse spray arms every few months to prevent blockages.
A non-obvious tip: If your dishwasher smells bad even after cleaning, check for food stuck in the drain or under the bottom spray arm. Sometimes, a piece of food gets trapped and needs to be removed by hand.
How Finish Dishwasher Deep Cleaner Affects Dishwasher Performance

- Longer machine life: Removing limescale and grease reduces wear on pumps and heaters.
- Lower energy use: Clean machines use less power because parts work better.

Is Finish Dishwasher Deep Cleaner Safe?
Many people worry about using chemicals in their kitchen. Finish Dishwasher Deep Cleaner is designed to be safe for household use. It contains cleaning agents similar to those in dishwasher detergents, but in higher strength.
- No residue: The product rinses away during the cycle and leaves no harmful residue.
- Septic safe: It is safe for most septic systems.
- No harsh fumes: Unlike some cleaners, it does not leave a strong smell after use.
Still, always follow the instructions and keep the bottle away from children and pets.
Environmental Impact And Disposal
Finish is aware of environmental concerns. The bottle is made of recyclable plastic. After use, rinse it and put it in your recycling bin if your local area accepts this type of plastic.
The cleaner itself breaks down in water and is not harmful in the small amounts used. If you want more details, you can check the manufacturer’s sustainability page at Finish Sustainability.

What To Expect After Using Finish Dishwasher Deep Cleaner
After the first use, you may notice:
- A clean, fresh smell inside your dishwasher
- Cleaner dishes and glasses, with fewer water spots
- Less noise during washing (if build-up was causing blockages)
- Quicker drainage at the end of cycles
If your dishwasher was very dirty, it may take two cleanings to fully remove old build-up. For most users, one cleaning is enough.
Comparing Deep Cleaner With Other Cleaning Methods
You might wonder if home remedies, like vinegar or baking soda, work as well as Finish. Here is a simple comparison:
| Cleaning Method | Removes Grease | Removes Limescale | Odor Removal | Safe for Machine |
|---|---|---|---|---|
| Finish Deep Cleaner | Yes | Yes | Yes | Yes |
| Vinegar | Yes | Weak | Yes | Can damage rubber parts |
| Baking Soda | No | No | Yes | Yes |
| Lemon Juice | No | Weak | Yes | Can damage rubber parts |
While vinegar and baking soda are cheaper, they do not remove limescale as well, and vinegar can wear out seals over time. Finish is designed for dishwashers and is safe for all parts.
Real-world User Experiences
Here are a few stories from real users:
- Maria, 42, from Texas: “I used to have white spots on my glasses all the time. After one use of Finish Deep Cleaner, they came out shiny. I now use it every month.”
- Ahmed, 35, from London: “My dishwasher was starting to smell. I tried vinegar but it did not last. Finish Deep Cleaner fixed the smell, and it has not come back.”
- Li, 28, from Toronto: “I did not know you had to clean dishwashers. After using the cleaner, the inside looked like new. It was easy and took no extra time.”
One non-obvious insight: If you live in an area with very hard water, deep cleaning alone may not prevent all white spots. In that case, using a rinse aid with every wash helps even more.
How To Store And Handle Finish Dishwasher Deep Cleaner
Store the bottle in a cool, dry place away from sunlight. Do not freeze or overheat it. Keep it out of reach of children and pets. Do not open the cap; only the sticker should be removed before use.
If any cleaner spills on your skin, wash with soap and water. If it gets in your eyes, rinse with plenty of water. See the safety instructions on the label.
