Do you find adding dishwashing helps for other weeds also ?

It has nothing to do with the type of weed. It acts as a surfactant.

let's say for fun that none of us actually know the purpose
of a surfactant is to cause the active ingredient of the
herbicide to stick longer on the surface of the foliage of
the undesirable plant. so, we'll look the word up in the
dictionary.

surfactant :a surface-active substance (as a detergent)

detergent :that cleanses : cleansing

so, the undesirable plant dies a clean death?
