I've used it (mostly on laundry) for years. have never diluted it. My friend had recommended it as septic tank friendly. After we bought our first travel trailer we found lots of people using it to clean their boats & RV's ( works great on thoses black streaks & bugs). Never heard of anyone diluting it, except for one person. He bought it in gallon bottles and that was stronger. You could see it was way more yellow.
