I was right about dishwasher pods, and now I can prove it

Quick Overview

The dishwasher powder formula, which lacks the pre-wash detergent step common in pods, successfully cleans dishes using hot water, but the overall cleaning cycle is significantly longer due to the machine's lower heating element wattage compared to models designed for pods.

Key Points: The dishwasher powder formula, tested against store-brand pods, achieved comparable or better cleaning performance across various food soils (cheese, bolognese, tea, egg yolk, starch, minced meat) in ASTM D3556 testing. The powder formulation cleans effectively without requiring a pre-wash detergent step, unlike the pods which are designed to release detergent in two stages. Dishwashers sold in North America, like the tested Frigidaire, often have lower heating element wattage (800-1000W) compared to other regions, making hot water pre-soaking necessary for optimal cleaning with powder. The test demonstrated that the powder fully dissolved during the pre-wash (9 minutes, 40 seconds), while the pod's PVA film took significantly longer to dissolve. When using the dishwasher's hot water supply (81°F/27.2°C pre-test), the powder's main wash cycle was notably shorter than when using cold water, which required an extra 20 minutes of heating time. The experiment confirmed that the powder's ingredients, including enzymes like protease and amylase, effectively break down fats and proteins, showing superior performance on greasy items like peanut butter when compared to pods. The manufacturer's design, which relies on the main wash to dispense the pre-wash detergent, is ineffective if the water entering the machine is cold.

Context: The video features a product review and demonstration comparing a new dishwasher powder formula (Green Llama Dishwasher Powder) against pre-measured dishwasher pods, focusing on cleaning efficacy, especially for tough, oily soils like peanut butter. The presenter conducts controlled tests using a portable dishwasher hooked up to a utility sink with a temperature logger to measure water temperature throughout the cycles, aiming to prove that powder detergents can outperform pods, even when the machine lacks high-wattage heating elements common in some older models.
