Well, it would be Tide,
but the question remains--which variety of Tide?
I really liked the early 90s "refill" package in the plastic bag, but the "Sanitizing" Tide of the late 90s was useful then (I know, I know, dryer temperatures can deal with most common microbes.)
I haven't tried the current variations, though Tide Cold Water powder sounded intriguing.
I guess it might be Tide with Bleach Alternative liquid, but only in the 300 ounce size (most of a
year, for me.)
