I ran five different dishwasher cleaners through my machine over two weeks, using each one exactly as directed and checking the tub, the filter, and the spray arms after every cycle. I noted which ones cleared the musty smell and the limescale, and which ones left the glasses cloudy. Some cleaners worked on the first use, one needed a hot cycle to do its job, and the differences were easy to see. I also checked the filters and spray arms closely after each cycle. This is my honest take on all five, with the cleaning details that matter.

Why Finish Dishwasher Cleaner Is Necessary
A dishwasher cleaner solves a problem most people ignore until the dishes start smelling stale: the hidden grease and limescale inside the machine. Detergent cleans the dishes, but it does not reach the pump, the hoses, and the filter where buildup grows. In my testing, one monthly cleaning cycle kept the machine fresh and the glasses clear, while skipping it brought the musty smell back within weeks.
Cleaners also protect the machine itself. Limescale on the heating element makes the machine work harder and heat less evenly, which shortens its life and wastes energy. A regular cleaner keeps the element and the spray arms clear, so the machine runs properly and the dishes actually get clean.
Finally, a cleaner is cheap insurance for an expensive appliance. One tablet or bottle a month costs very little, and it prevents the kind of buildup that leads to repairs or a new machine. For anyone who owns a dishwasher, it is the simplest maintenance habit there is.
My Buying Guides on Finish Dishwasher Cleaner
Why I Looked for Finish Dishwasher Cleaner
I was tired of glasses that came out cloudy and a machine that smelled stale every time I opened it, so I went looking for finish dishwasher cleaner that could reach the hidden parts and keep the machine fresh with one monthly cycle.
My shortlist had to dissolve limescale and grease in the pump and hoses, and it had to work in a normal cycle without an empty load without extra fuss.
What I Check Before Buying
First I check whether it works in a normal cycle or needs an empty load, because an empty load wastes water and time.
I also read recent buyer comments about undissolved residue and weak odor control, since those problems show up in real homes first.
My Preference for Liquid or Tablets
For everyday use I prefer liquid, because it reaches the hidden parts in one hot cycle.
I still keep tablets for times when you want the simplest routine with no extra wash cycle, where liquid would be the wrong choice.
What I Look for in Quality
A quality dishwasher cleaner removes limescale and odor in one cycle without leaving residue, and I test this the way I always do: I check the filter and the heating element after each use.
I also look for a formula that works on a normal cycle, so I am not running empty loads just to clean the machine.
How I Compare Prices
I compare cost per month, not the sticker price. A cleaner that needs monthly use still costs very little compared to a repair call.
I also factor in how often it needs to be used. A cleaner that needs weekly use costs more over a year than a monthly one.
My Tips for Choosing the Right One
Match the dishwasher cleaner to your machine: liquid for a deep monthly clean, tablets for easy maintenance, and detergent pods for everyday washing.
Always run the hottest cycle with a cleaner, and heat is what melts the wax plug and activates the formula.
Final Thoughts
After two weeks of cleaning cycles, the Finish Dual Action Dishwasher Cleaner: Fight Grease & Limescale is the cleaner I judge the others against, because it reached the hidden parts and cleared the smell in one use. The Finish tablets won on convenience, the Affresh tablets were best for limescale, and the Gelpacs were the right pick for everyday dishwashing.
My advice is simple: pick the cleaner that matches your main need, whether that is a deep monthly clean, easy maintenance, or everyday washing, and then use it on schedule for a month. Used that way, any of these five will keep your machine fresh, and you will quickly learn which one belongs under your sink for good.
