They Figure No One Uses Bluing Anymore
Give that man a Kewpie doll! *LOL*
With most major laundry detergents and other additives packed with OBAs and other whitening agents, bluing pretty much as died out. Damn hard to find the stuff in many areas. Besides in the long run, OBAs work much better over a wider array of man made and natural textiles than bluings ever could.
Being as the above may, use bluing now and then for certian linens and other whites. When one does use bluing it goes in the final rinse, or starch bath.
Rarely use fabric softener, but for loads that require extra brightening and plan on adding the stuff to the final rinse, one just uses any detergent with OBAs, such as Persil or Tide "Pro-Line", for the wash.
Never liked using bluing in the wash bath because long contact time with bluing can make laundry grey and dull. Besides the wash cycles on my Miele are too long for such things.
