Strange I've always found Tide to be suds happy. Persil can easily suds up, but it also seems to "deflate" just as fast. I was staying at my parents and did laundry there. They have an older LG front loader (it has the soap dispenser on the top of the unit under a door, and an almost front loader style control panel.) And with the permanent press cycle, and about 1/2 the way up the first bar it gets really sudsy. My dad thought I had put in too much soap because of how bad it was getting. It rinsed out clean though, no issues at all.
The worst detergents I found for suds have been: All (blue bottle from Sam's Club), ERA, and Arm and Hammer. The cheer I use now can get sudsy, but they all rinse out just fine.
I honestly just want something that doesn't make me stink like a flower, doesn't have an overpowering scent, and cleans well. Is that too tough? I'm considering mixing half a bottle of Persil regular with Persil unscented. Might do the trick. Would still rather have their powder though.
