That is certainly the more comprehensive clean if the dust has etched in, I was erring that day old dust shouldn’t be too bad once it’s been softened by the snow...Not far off what i would do John. This is what I would do in this instance from how the car is described. May change once i saw it as can never really tell until you physically see the car.
Pressure washer rinse.
Snowfoam (with Traffic Film Remover and All Purpose Cleaner added) and leave to dwell for 20mins assuming not in direct sunlight
PW Rinse again
Spray the car with Iron-X whilst still wet and let dwell for 5 mins
PW Rinse
Iron-X again whilst still wet to see how last application did. Dwell no longer than 5 mins
PW Rinse
Snowfoam (only) again and leave to dwell for 5-10 mins to ensure no Iron-X remains.
Wash using a lambs wool mitt
PW Rinse, dry off and wipe the whole car down with IPA (isopropyl alcohol not the beer! )
If that didn’t remove it then next step would be to clay the car. But that would introduce micromarring so as wouldn’t be machine polishing would try and avoid.
Once happy then reapply protection of choice. AG SRP would useful if you clay the car as it is full of fillers so would hide the micromarring.
Regards the power level of the pressure washer. When rinsing the car I always use full power. I never get closer than a couple of feet to the car so wouldn't make any differnce. Anything loose/lifted will be caught up in the water until it gets outside the spray area. After that it doesn't matter what setting you're using as it's going to run along/down the paintwork anyway.
Something i forgot to mention Peter is rinse from the top down. Only because anything that is falling down the paintwork is falling along the other crud on there so will negate any minimal damage it could potentially cause. It also helps you see what has/hasn't been done.
Like your approach much better, hadn’t thought of using iron x.... still so much to learn( and get obsessed with )
