In order to simplify things as much as we could, we want to make our rubric easy to follow. That is why we decided to focus on three important attributes for a washing machine cleaner: power, application, and odor.
We will now take a moment to break down how those categories specifically apply for each and every product that we reviewed.
Power: Where power was concerned, we were mainly focused on how concentrated the formula was and how much of the bottle we needed to clean out our washing machines in one standard cleaning session. If we felt the formula was watered down in any way or was not concentrated, we lowered the product’s score in this particular category.
For the purposes of complete transparency, we will mention that we weighed this category more heavily than the other two in terms of developing our final composite score. The reason for this is that the less powerful a washing machine cleaner is, the more of it you will have to buy to complete the task at hand. We felt that it was important to protect consumers from ineffective products, so we reflected that feeling in our scoring system.
Application: In this category, we were mainly focused on how easy the product was to use, in terms of getting it from the bottle or box to the washing machine, and the overall conditioning of the packaging itself. If the packaging was in any way, shape, or form defective, or if we had trouble simply using the product in general, we lowered its score in this category.
Odor: Of all three of our grading categories, this one was by far the most straightforward to grade on. There is no reason that a cleaning product should have an unpleasant or nasty odor, and if we did notice one among the washing machine cleaners that we were testing, we made note of it and lowered its score on this part of the review gradient.
