An earth friendly dishwashing liquid is pretty low-impact, FWIW.

Alternatively, a lot of other create your own cleaning recipes use loquid Castile soap, which is a plain soap liquid based on olive oil & glycerine.

I find bicarb & vinegar to be useful but only when used separately, because the addition of the vinegar (acid) to the bicarb (alkaline) neutralizes both. I use bicarb when I need scrub or deodorize factor, and vinegar when I need to cut thru grime/grease.
