Tide Liquid Detergent
I swear by tide laundry detergent. I use either just the regular scent, or their newer simple pleasures detergent (just because it smells so darn good).
I have used both powder and liquid forms, and I prefer the liquid. This also works really well in pre-treating any major stains. The newer concentrated liquid detergent seems to work great as well.
The only complaint I have about the concentrated kind is that it sticks to the dispenser cup in a bad way. But keep rinsing and it'll come off. :)
Tide is a little more expensive than other detergents, and when money started to become an issue I did branch out and try other brands.
However, you get what you pay for, and Tide definitely made me the most happy. One great thing about Tide is that it is a popular brand and you can always find coupons or a sale on this detergent.
You just have to look around a little bit more!
Tide does a great job getting out stains without any extra work. It also keeps colors bright and whites white. When you spend so much money on clothes, the worst thing is to wash them and have them come out looking less than new. Tide helps keep my clothes looking in great shape. I love the brightness in color that it helps maintain!
Finally, I love tide because it smells good. There is nothing like a load of laundry that smells freshly of Tide. :)
