Discover the Top 8 Dishwasher Cleaners of 2025: In-Depth Review

Even the best dishwasher detergent cannot produce spotless glasses and plates if your machine is dirty. Considering all the bits of food, grease, and hard-water minerals that collect inside your dishwasher, regular cleaning is crucial to maintain its performance. A dirty, smelly interior can keep a dishwasher from performing at its peak and is simply disagreeable to use. A fresher, better-functioning machine is just a cycle away with the best dishwasher cleaners. Dishwasher cleaners power away grime, food residue, and mineral buildup from inside the machine. Keeping the dishwasher gunk-free will improve cleaning performance, cut down on odors, and help maintain a hygienic appliance. Formulated to banish grime from hard-to-clean areas such as the racks, drains, and spray arms, a good dishwasher cleaner is key for dishwasher maintenance.

Here are the top eight dishwasher cleaners for 2025, carefully selected based on performance, ease of use, and customer feedback. Each product has been tested for its ability to remove grease, limescale, and odors, ensuring your dishwasher stays in top condition.

1. Cascade Platinum Dishwasher Cleaner

Cascade Platinum Dishwasher Cleaner comes in a convenient, single-dose packet you can pop into your dispenser every month. In our Lab tests, the concentrated powder-gel formula effectively removed bad odors, limescale, mineral deposits, and grease. While a dishwasher may appear clean, these deposits can settle on the spray arms, the tub, and parts you can’t see of your appliance. This heavy-duty dishwasher cleaner is one we’ve happily restocked and one that several of our editors and writers reach for monthly¡ªeasily making it our top pick. To use this dishwasher cleaner, you simply add it to an empty dishwasher and then run a normal cycle. The pod does the rest of the work, leaving you with a shinier wash tub and less stains, in our experience. It effectively removes grease, and gets into the hard-to-reach and tight corners of your dishwasher.

• Benefits: Easy-to-use pod format, removes grease and limescale effectively, fresh scent comparable to Dawn dish soap.
• Drawbacks: Not suitable for those sensitive to fragrances, does not clean the filter.

2. Affresh Dishwasher Cleaner

If you’re looking for a cleaner that’s also in tablet form, like our overall best, but want something with less package waste, consider this editor-loved pick, the Affresh Dishwasher Cleaner. Nearly 28,000 reviewers give this dishwasher cleaner five stars, and many agree that it works miracles on extra grimy dishwashers. “We haven’t done any cleaning on our dishwasher in five years, and the sliding dish trays were tough to pull out or push in, there was detergent build up all over the inside, and there was a milky film on all our cups,” one reviewer says. Simply place the tablet onto the floor of the machine and your detergent in the dispenser and run like usual. In just one cycle, these tablets cleaned plates, added a lemon scent to the machine, and busted limescale and mineral deposits from hard water in our Cleaning Lab tests.

Then I read about this product and decided to give it a try,” they write. “It is simply amazing! I ran it through the regular cycle once and 95 percent of the stuff was just plain gone.” Since then, they’ve used the powder with every wash, “and the dishwasher looks brand-new!

Buying Guide for Dishwasher Cleaners

To keep a dishwasher in top shape, it’s important to clean it regularly, about once a month for most machines and households. However, it’s difficult to reach all the interior parts, and that’s where a dishwasher cleaner comes in. The factors and features to keep in mind when evaluating the performance and safety of the best detergent to clean dishwasher interiors include ingredients, certifications, ease of use, and scent.

• Ingredients: Dishwasher cleaning products contain a variety of active ingredients to scrub the inside of dishwashers clean, including citric acid, alcohol, borax, surfactants, and antibacterial agents. Avoid cleaners with bleach, which can damage the stainless steel components of some dishwashers.
• Certifications: The main logo to look for is EPA Safer Choice certification. Products that are EPA Safer Choice certified have been evaluated by the EPA and confirmed to have ingredients that are safer for human health and the environment.
• Ease of Use: All of the best dishwasher cleaners are designed for ease of use, but each type comes with its own benefits. Pod and tablet cleaners are extremely convenient; just place them in the dishwasher and run the cycle. Pods tend to have a dissolving plastic layer around the liquid or powder cleaner inside, whereas tablets resemble small, hard pucks made of concentrated cleaning powder.
• Scent: Some cleaners leave a fresh lemon or neutral scent, while others may be fragrance-free for sensitive users.

For those with a septic tank, it’s crucial to use a dishwasher cleaner that is suitable for this type of wastewater management system. Look for products labeled as “septic safe,” as these cleaners will have gentler ingredients that won’t disrupt sensitive septic tanks. In areas with very hard water, look for a dishwasher cleaner formulated to tackle the extra mineral buildup. These cleaners are often advertised as suitable for hard water and often include such ingredients as citric acid, sodium carbonate, and sodium citrate to break down residue and soften water.

Best Dishwasher Recommendation

For optimal performance with these cleaners, we recommend the Bosch 500 Series SHP65CM5N. This dishwasher delivers across the board and is quiet to run, has a generous capacity, and a third rack. Plus, it’s Energy Star certified, making it an efficient choice for regular cleaning cycles with the above cleaners.
