as long as you stick with a name-brand premium, you're OK

sigh...placebo effect at work, gentlemen

it doesn't matter so long as it's a high-quality premium. most detergents are the same these days, just like most cleansers, regardless of brand, use the same detergents and surfectants. everything else is hype and marketing.

brad is right. most major names are the same at the premium level. start going to costco or big earl's gas hut and laundry emporium, then caveat emptor.
