I've never underestood the need/fascination with having a varietyt of detergents as I see it totally superflous and a waste of funds. Always had just one brand of detergent at a time and it was usually the same brand for years. The only reason it changed to having two (see my post above) is because I expanded to adding powdered Tide w/bleach alternative was because I started having front loaders with onboard heaters raising wash temps to 140-150F degrees and taking advantage of oxygen bleach prowess. Same with fabric softeners and chlorine bleach when I did use it--which hasn't been since 2010 with the WP Duet HT.
