The cold-water cycle still got a stubborn coffee stain out of my white shirt, which surprised me since I didn't pre-treat it at all. It's also nice that there's no optical brightener smell lingering on my towels afterwards.

The bottle lasted way longer than my usual detergent since it's ultra-concentrated, and the enzyme mix lifted a week-old coffee stain out of a white tee in cold water without any pre-soaking. Front loader had zero residue, and I didn't catch any chemical smell on my clothes afterward.

I was skeptical about switching to a detergent without optical brighteners, but my white shirts look just as crisp after a month of use. The ultra-concentrated formula means one tiny capful handles a full load, and it works in warm water without any residue.
