<span style="text-decoration: underline;">Linens, towels, sturdy cottons</span>: Tide HE or Gain HE, powder only. Liquids gunk up the dispenser and tend to leave residue. Powders don't leave a dispenser mess, and presumably rinse cleaner out of clothes as well.
<span style="text-decoration: underline;">Work clothes (office casual, 100% cotton with wrinkle-free finish): </span>Henkel Persil, Unilever Persil/Via, or Ariel, all brought over from Europe by friends returning from Europe or from my own travels there. Just returned from UK with four boxes of Ariel. All of them bio powder, and since I have very few white pieces of clothing, all of them are the color formulation. My favorite is Henkel Persil Megaperls for color.
