I now retract my previous statment...
Bought Tide Ultra HE for the neptune today. After several loads, all I can say is OMG.. It is like having the best of both worlds. It does just as well on colors and brights as liquid, no stiff scratchiness, no little white flecks. And though I always thought my whites looked good, now they look amazing! I gave it a real test, didn't pretreat anything, even the oil and grease stains on white towels and rags from cleaning up after the failed Atlantis. Everything came out. I used bleach with my whites as always, but with the Oxydol powder I was using before, I would have been hard pressed to get those stains out even with Spray and Wash.
Same thing on muddy and grungy lights and brights, everything came out perfect. This just became my new favorite all around detergent.
