IIRC many fabric softeners today contain whitening agents/OBAs. Normally don't use FS, but on those rare occasions one does use Ecover's version. Nice scent and just the right amount of softness.
Speaking of "blue" detergents, just nabbed a case of the old "Biz" laundry bleach/pre-soak. Love the scent and was totally ticked of when Lever Bros sold off the brand and couldn't find the old formula anymore. If one had only known, since K-Sears had a shelf full of the stuff, but alas who knew?L.
