We have over 35 years of experience with performing tests on different types of products in various industries and have learned the usefulness of creating categories during our process. The categories allow us to rate each product and compare them to one another. The testing categories for the powdered dishwasher detergent products that we tested include power, convenience, and odor.
Power: The power of each powdered dishwasher detergent was one of our main categories for testing each product to determine how well it cleaned the dishes and if any of the dishes needed to be rewashed during a second load. We evaluated how much food was left behind on the dishware and if water spots were present once everything dried.
Convenience: One of our top categories was the convenience of using each product when handling it and adding it to the dishwasher. The packaging contributed to how convenient the product was to use and also details the clarity of the instructions that were provided.
Odor: We evaluated the odor and scent of each dishwashing detergent powder to determine if it smelled natural or overpowering, which contributed to its appeal and value. We also considered if it smelled like chemicals or had a natural aroma.
