Sorry, (IMO only slightly) off topic but: Even if you don't polish the car, you should get some sort of LSP on there. There are lots of good options for Wipe On Walk Away style sealants that not only help the car look better, but to your wife's point: Cut down on time required to clean the car. Possibly even easier are the Sio2 "Mist on, hose off" options like Hydro Blue, etc.
I put more focused attention to my wife's car than my own, including always having some sort of wax or sealant on it (even though I haven't had time to give it a proper compound/polish), and the difference in time and effort required for a basic car wash is noticeable. Cleaning my car sped up noticeably when I started using Optimum Optiseal as a drying aid (no more time required than drying the car normally - actually, drying goes faster) or recently when I tried McKee's Hydro Blue.
On topic - For a strong soap, Car Pro Reset comes up often as a leaves-nothing-strips-everything car wash (usually referenced for coated cars where you want to restore the coating's properties).
