Where to Buy

Finish Quantum (*Est. 23 cents per load) is the only dishwasher detergent that all three of our top sources recommend:, Good Housekeeping and Real Simple. In Good Housekeeping's test, Finish Quantum tackled cooked-on food better than any other detergent, editors say, and they name it the "crusty cookware champ." Real Simple's reviewers say Finish Quantum "got dishes shockingly clean," and it is named the best detergent pellet in their test.

At, the review is positive overall, though when hard water performance was factored in, Finish Quantum fell from first place to third. User reviews seem to dispute this, however. At, more than a few reviewers specifically mention how well Finish Quantum works in their hard water.'s housekeeping guide Sarah Aguirre rates it highly as well. Aguirre names Finish the best tablet detergent, although her review criteria are unclear, as is how she tested these detergents. (Note: ConsumerSearch is owned by, but the two don't share an editorial affiliation.)

With more than 100 reviews and an average score of 4.7 stars, Finish Quantum is the top-rated dishwasher detergent on, but a couple consumers do note drawbacks in their reviews. Like many dishwasher tablets, Finish Quantum doesn't always dissolve completely in short-wash cycles, and a couple users complain of a very strong and unpleasant chemical smell when first opened. We found a handful of similar complaints at, too. But in general, the vast majority of consumers at both sites say Finish Quantum works very well.

If Finish Quantum does, in fact, fail to work in your hard water (leaving a filmy white deposit), Cascade Complete Pacs (*Est. 23 cents per load) are almost as highly reviewed, and some users say they're better for hard water. It's hard to predict how either will perform in a given user's water, though.
