I bought a jug of it several weeks ago and put a red tee shirt, a pair of denim jeans and a white baby diaper in a load among other mixed colors. The white diaper was white after washing. I've about used up the bottle and so far everything has been clean. The next new pair of denim jeans I buy I'll wash them with some yardage of white muslin fabric for the ultimate test. Being paranoid of detergent is for real?
