If I'm not able to fully rinse the vehicle, I will use the Spray and Wipe and go over the vehicle with WET microfiber towels, then come back and use the Spray and Wipe again with the some dry microfiber towels.
This has worked out really well.
I had considered using wet MF towels for the first wipe off of the S&W. Actually, I was thinking of using warm water for the first wipe.
My reservation was the possibility that the water would dilute the S&W and keep it from doing its job properly.
If I'm going to go that far, I just as well do a hybrid job. S&W where I feel comfortable with it. (Most of the area above the midpoint of the doors and fenders)
4 in 1 for the lower panels and any really dirt areas.
Maybe even mix up some 4 in 1 in a spray bottle to saturate the caked dirt before using the S&W. The 4 in 1 would make a much more economical soaking solution than the S&W.
Usually, I go to the DIY spray wash for a first rinse when the vehicles are bad, but there are times when it is much more convenient to just leave the vehicles in the garage. Opening the garage door to leave and return loses any residual heat the garage had and also gets the vehicle it self colder.
Since I seem intent on making this into a big deal, maybe I can try all the above.

By the time I figure it out, spring might be here.
