I don’t think a full traditional wash is better than rinseless!

How do RW users clean their undercarriages?

Sure, I can do them on the Garage Queens (well, the ones that don`t leak much) with a RW..*for a while*..but eventually even those need conventional washing under there. And those aren`t even being driven through Ohio winters...I can`t imagine just RWing the underneath of the winter-time Daily Drivers and even if my mechanics and I didn`t care, they`d be messes (how could I spot any new leaks or an emergent need for service?) and would simply rust out in no time if I let `em go.

I have Woolwax on my undercarriage. I will lightly hose it down periodically in the winter to remove salt but that is about it.

Eh, I suspect that the undercarriages are one area where I`m more Autopian than I usually am these days

Even before my vehicles all got so old as to need regular inspection under there, I`ve just always been kinda fanatical about keeping `em as close to white-glove clean as I can Heh heh, if nothing else, my Techs love it, so that helps make up for my "never touch my paint!" stuff.
