I just washed several white sweat and tee shirts this morning. Inexpensive shirts, purchased at Walmart of course. I didn't add any bleach at all. I was surprised when I took them out of the dryer to fold them at how soft and white they were. You know, after you wash white things several times they never seem to look really white again but these have all been washed several times and they were still soft, fluffy and white. I just had to write a review as I'm so pleased. I use the Tide Cold Water detergent for all my colors and get the same soft results.
