Is this salty enough for you?
We often go for many weeks without seeing one day above freezing. I prefer not to leave my car covered with all the road crap for that long, so QEW is a total lifesaver to me.
I tried washing the Maxima with the hose once, when it was below freezing. It doesn't take long for it to freeze, and it looks worse covered in ice than it does with the dirt/salt on it. Leave it alone unless you are washing one panel at a time with QEW.
Neo - the polymers in QEW and QD encapsulate the dirt particles on the paint, breaking their contact with the paint. This is also what causes them to fall to the bottom of the rinse bucket faster. Many of the particles are so small that they would take a VERY long time to settle out on their own. The polymers bond with the dirt particles, and increase their density in the rinse bucket. The same process is used in wastewater treatment plants to remove the dead bacterial cells, which would take far more time to naturally settle out than could ever be allowed.
