I have been trying this new way of washing. Now it may seem counter productive to efficiency.
I have heard from someone (possibly Ivan) about presoaking with ONR then rinsing the car with water prior to anything.
This is my current experimental routine which applies to ALL washes for the sake of consistency everytime I wash a car with a water source. I personally use a hose with garden sprayer attachment on a "flat" spray setting (similar to pressure washer). I also wash my vehicle in NIGHT TIME as I am in the desert heat. The following steps can still be applied without a water source, which would increase efficiency, but I would take POWER Clean out of the routine and also not work in the wheel barrel for wheel cleaning.
1. Presoak the car with ONR and let it dwell. Spray Tires/Wheels with Power Clean. Take the ONR wet wheel/body brush and go over all the wheel faces, tires quickly. Rinse off ONR/PowerClean with hose/pressure washer.
*The dirt should be encapsulated and some of the dirt/grime should be rinsed off better this way.
2. ONR wash with BRS. Rinse again with hose/pressure washer.
*The contact wash should break off any bonds (static) that some dirt/grime had on the paint which should now be rinsed easily off the car. I noticed that if you pressure wash a dusty car, some dust may still be stuck on paint due to static, which requires contact wash to break this bond.
3. ONR wash with Cyclone wash mitt.
*This should be a quick step as most of the dirt/grime is gone from the car. Using this step ensures whatever was not picked up by the BRS/Rinse cycle would be picked up here so that the drying towel would not pick up any unforeseen dirt/grime.
4. Spray down entire car with ONR. Dry the car with Plus Twisted Loop towel
5. Use ONR wet microfiber towel on wheels, tires, brake calipers. If working into the barrel with Wheel Woolies, I would spray the wheel down again with hose after the wash.
6. Dry Wheels with Opti Seal and Microfiber towel .
7. Apply Last Step Product of choice on the paint/windows/soft top/tires
