Tested powdered Tide Professional on a purposely stained kitchen towel, this time using cool water. I paused the washer as it began to drain the wash water—it still drained the rest of the water, but I was able to stick an instant read thermometer into the load and it registered 74 degrees F. As it had just completed a 50 minute wash tumble, I assume the water was at least a few degrees higher earlier in that portion of the cycle.
Interestingly, although it may be hard to discern in the photos, Tide Professional was slightly better at removing the very tough stains in warm water—around 100-105 degrees F.
Several other items in the load had smaller, garden variety stains on them: chocolate syrup & Rao’s marinara on a cotton/poly blend shirt; soy sauce, blood, blue shaving cream and Colgate charcoal toothpaste on kitchen and bath linens. All of those stains were completely removed.
FYI: Cold tap water here—having purged the pipes of the warmer “indoor” water—is currently 57 degrees F. Since the cool water test was not an improvement on the warm water test, I’m not going to bother testing Tide Pro in tap cold.
For this latest—and last—test:
Washer: front-loading Speed Queen model 7009; Normal cycle; max soil level (50 minute wash tumble); cool water setting.
Detergent: 60g powdered Tide Professional detergent.
Kitchen towel was stained, then allowed to dry for 12 hours before laundering.
