Default Pre-treat weeds with soapy water before spraying weed killer?

I mix concentrated Ortho Weed B Gon (Plus Grabgrass Control) with water

I suppose that it works, but I don't exactly see the spray "wetting" the
leaves and stems of the stuff I'm spraying. Looks more like most of it
beads up on the leaves and runs off.

I'm thinking that this stuff would be more effective if it "stuck" to
the leaves, and I think that's only going to happen if the surface
tension is reduced, possibly by pre-spraying the weeds with soapy water,
or alternatively maybe adding soap in with the weed killer and water.

Does anyone have a clue regarding if the effectiveness of water-soluble
weed killer is increased if a surface-tension reducing agent is used?

And just for clarity, Ortho Weed B Gon contains:

2,4-D (Dimethylamine salt)
Quinclorac
Dicamba (dimethlamine salt)

Hi,
In this city chemical week killer wass banned few years ago.
We use DW liquid+salt+vinegar to kill weeds and use arm
strong power to physically remove weeds in our small city lot.


Bu . . bu . . but:

DW liquid+salt+vinegar is a chemical weed killer


Hi,
You're right but it won't make our dog or neighborhood small
children sick or who knows even die.
