Of the 20 products tested, those with enzymes did a much better job, which is why some brand name enzyme-free gels pulled low marks.
The clear winner: Cascade 2 in 1 Action Pacs. It rated 95 out of 100 points. It's also one of the higher-priced products.
Looking to save some money? Cascade Pure Rinse rated an 87 and earned a CR Best Buy. The editors say it does "an excellent job of getting rid of gunk baked onto plates" and it's reasonably priced.
Trader Joe's powder (with an overall score of 83) is another CR Best Buy. It's also a green choice, since it does not contain phosphates.
Ecover tablets, which tied for second place in the ratings (scoring 89) are also phosphate-free.
Consumer Reports found that some detergents are hard on utensils made from silver. That's why the magazine says it's best to play it safe and wash silver by hand; same goes for crystal.
