So we're finally on the road; I took out my can of Kwikee Kwik Lube and rolled under the step. Luckily no dirt anywhere, so I started spraying the Kwik Lube. The stuff comes out of the can like any aerosol (WD-40, silicone spray or whatever) but after the carrier (aerosol) evaporates, Kwik Lube leaves a very sticky (in a grease type way) film, slightly red in color. Makes me think of Marvel Mystery Oil. Cycled the steps a few times, all OK; now, onto cleaning the windshield, windows, wheels, well, you get the picture.
Wishing all the best as we emerge and travel about!
