Best Dishwasher Detergent Powder of 2026

"I wanted to stop using pods because I heard they don't always dissolve completely and can cause build-up in the dishwasher. So, I switched to this powder. It works effectively as long as you don't use too much. The box is quite heavy and it's a bit awkward to pour it into the machine. It might be best to transfer some into a smaller, more manageable container. Overall, I would recommend it."

"I prefer powder over liquid, pacs, or gel. This product usually offers the best value per ounce and it's very effective. The fragrance isn't too strong. It leaves the dishes clean without any slimy residue. I use less than the recommended amount, so the box lasts a long time. It's quite heavy, so I pour smaller quantities into a quart pitcher."

"I'm a big fan of Cascade powder detergent. I find it easier to use and more effective than the newer gels and tablets. For those who have issues with a white film, it might be your water rather than the detergent. We have very hard water with a lot of lime. It even ruined a dishwasher before we installed a water softener. If I forget to add salt to the softener, I end up with a white film on my glasses! Once I add salt to the softener, the problem is resolved!"

"I chose this detergent primarily because it's in powder form. I was fed up with large plastic bottles and brightly colored pods. The powder allows me to control the amount used and it appears to clean more effectively. The only issue I encountered was that the bag didn't seem to be biodegradable, but it's still more eco-friendly than those large green bottles. I've grown to like the powder and I believe my wife has too. Sometimes we unconsciously choose detergents that continue to harm the environment for decades after they're empty."

"So far, it's cleaning very effectively, not leaving any spots or residue, even on my clear glass dishes. I haven't had to rewash anything like I did with my previous detergent. I've been using it for a couple of months now and plan to subscribe to it since it has proven its worth. I recommend adding some white vinegar to the rinse aid compartment to prevent water spots."

"This detergent works wonderfully! It doesn't leave any streaks or chemical smells. It cleans my dishes perfectly every time and I appreciate that it contains natural ingredients. My only complaint (and the reason for deducting one star) is that it's expensive and the bag is only half full, which is both wasteful and misleading."

"Our water is extremely hard due to calcium, not iron. There are only a few dishwashing products that work with our dishwasher, particularly those that aren't harmful. Nellie's has once again come to our aid! A single scoop of this, combined with vinegar for shine, leaves our dishes spotless. Best of all, they have no scent, which is exactly how it should be!"

"Most well-known dishwasher soaps compete with each other, promising to remove the most grease and grime from your dishes. Over time, I found that they gradually stripped the outer layer and colors from my best plates. I sought a gentler option and discovered Nellie's. I've been using it for over a year and it does a fantastic job."

"I've used Cascade my entire life. I had to add Lemmishine to try to remove the film on my dishes. I essentially had to wash my dishes before putting them in the dishwasher. I assumed it was due to my hard water or my dishwasher. I was astonished by how clean my dishes were after using Nellie's! Even dishes with dried food on them come out clean and I use half the amount of product I used to. I've told everyone I know about this incredible product."
