cheap detergents.
Have a friend and his wife who are cheap, cheap ,cheap.
Saw a jug of the nastiest, cheapest laundry detergent on the face of the planet sitting on the washer.
Load of washed whites were piled in (and above) the laundry basket.
They were so *unintentionally* uniformly yellow (unlike that flea-bay auction prior post which is a whole other story).
screamed either or both:
1) bad techinque
2) soil is not suspended and flushed away, but rather re-deposited.
Ii there a bigger clue that one is buying water with scent and color and suds, not decent detergent?
I was a good boy and kept my mouth shut!
