Post blizzard wash .. post ski trip wash

New England vehicle here I've used ONR veryy happily since October but it's been a heck of a winter The Gx470 does ski mtn duty and it's covered in post blizzard salt snow etc as I ride it get thru the snow storms to help neighbors and family.

Game plan to clean her up? Self service wash then soap , let it soak then rinse , then soap with mitt then rinse rinse and rinse ? Then ONR?

Last time I did the soap, rinse, soap, mitt and rinse and still had soapy streaks. Didn't have time to ONR with a trip up north .

Not looking for perfection. Just minimize within reason any major swirling/ scratches It's undercoated with woolswax so no worry about rust
