When it comes to keeping dishes spotless and maintaining the performance of your dishwasher, choosing the right detergent is crucial. To find out which dishwasher detergent comes out on top, we asked three experienced plumbers for their professional opinions. Remarkably, they all agreed on the same one.

The consensus was clear: Cascade Platinum ActionPacs are hands down the best dishwasher detergent according to the plumbing experts we consulted. Each plumber emphasized that Cascade Platinum’s powerful formula not only removes stubborn food residue and grease but also helps keep dishwasher drains free of clogs.

One of the plumbers explained that a good dishwasher detergent should be tough on food remnants but also designed to protect the inner workings of the dishwasher. The enzymes and surfactants in Cascade’s formula work effectively to disintegrate food particles, which can prevent blockages and extend the lifespan of a dishwasher.

Another plumber noted that Cascade Platinum ActionPacs leave dishes with a streak-free shine—indicating that cleanliness doesn’t come at the expense of aesthetics. This is particularly important in hard water areas where water spots on glassware can be a persistent issue.

The third plumber pointed out that these ActionPacs work exceptionally well even on short cycles or lower temperatures, which can reduce water and energy usage. This makes them an eco-friendly choice for environmentally conscious consumers.

It’s rare to have such agreement among professionals, so when you’re next in need of restocking your dishwasher detergent, consider reaching for Cascade Platinum ActionPacs—the unanimous choice among our sample of plumbing professionals.
