Tide 洗衣粉 - 1.4 盎司

That concentrated formula really is no joke — a third of what I used to scoop did a full load and the Acti-Lift crystals got out a set-in grass stain I'd basically given up on. Only gripe is I keep over-pouring out of habit.

I honestly expected to rewash my husband's grass-stained work shirt twice, but the Acti-Lift Crystals got it clean on the first cycle. A single scoop handled a whole load since the formula's so concentrated.

The powder dissolved fine in cold water and got out a set-in coffee stain I'd given up on. Only downside is the single-use packet size, which feels wasteful if you do a lot of loads.
