I take back everything negative I said about Persil
Curiosity got the better of me and I bought a bottle of 2 in1 and the Power Pearls, and I tried again.
The first time I tried it again, I had an oversuds in the SQ FL and the load did not get clean, as with any oversuds. Once I figured out the right dose, I started getting fantastic results. My window washing and housecleaning rags are noticeably cleaner after a few washes. It seems easier on colors than Tide, and rinses out way easier. In the FL a dab of 2in1 in the pre wash cup, 1/2 teaspoon Power Pearls in the main wash cup and a scant Tablespoon Clorox chlorine bleach, plus some extra rinses, yields dazzling white tidy whities. (That's with a water softener, BTW -- probably more would be needed in unsoftened water or with really big loads.)
Unlike the first time, I've never again had an unpleasant or overpowering scent with these 2 formulas either. If there's any scent left, it's very subtle and is like the fresh, outdoor line-dried scent reminiscent of childhood -- nothing like the scent of the detergent itself. To me the detergent itself has a kind of cherry scent, on the masculine side compared to the others, and then during washing it smells different, sort of like bananas. It's interesting how it changes. Either that or there's something way wrong with my sniffer. I dunno. A lady in the store opened a bottle and said it smelled like a Christmas tree. I don't smell any pine scent but she might very well be right.
