So I live in Alberta where it is against the law to drain out water from washing your car into the storm drains. So unless you are just spraying down your car you have to go to a self wash to clean you car. During the winter they use gravel and dirt (instead of salt) to combat icy roads so my car does get dirty quick during the winter. My question is this:

Can I use ONR (cut with water maybe!) in a spray bottle to loosen the dirt and then use a high pressure wash to rinse it? Right now all I do is spray down the car about once a week so the dirty doesn't cake up, but I still ahve residue dirt left on the car. Will using ONR help?

I'd spray it down at the self wash like you're doing, then go home and do a regular ONR wash. That way you're getting rid of all the dirt with the spray, then cleaning the paint with ONR.

Use the presoak feature at the wash, then spray the majority of the crap off your car and then just do a regular wash.
