The scrubber may do several more items without having to use any more. The oat meal, egg or cheese residue may just need to soak a little longer just leave tm in the sink while rinsing other things.
I do the same, except that I have noted that Dawn PowerSpray, as the spray form is called, is somewhat more efficient in cleaning greasy things, so I buy PowerSpray refills as needed. Both formulas seem to have left the competition "in the dust" (or the grease

).
As you noted, a little goes a long way, a point I think Paul undersold. I'm on a well and septic system and can see no negative consequences from any of the soap/detergent that my wife and I use. We use water-efficient appliances, treat our well water for unpleasant mineral content, and get the 50 year old septic tank pumped out about every 8-10 years (whether it actually needs it or not) and have never experienced any sign of a problem. For me, efficiency is the primary consideration, whether of amount of cleaner and water used or the time and physical effort required to do the job.
By the way, the last time I did my semi-annual car wash, I discovered that Dawn PowerWash worked as well as specialty sprays for cleaning road "tar" from the door bottoms and rocker panels.
