Bob, part of the problem is that I don't think most of the soiled items are sturdy enough to stand up to the sanitize cycle. With industrial strength pre-treating (aka a nozzle tip on the garden hose) and some additives like borax and/or all-fabric powdered bleach, I can get by with heavy duty/high soil/stain clean/hot wash/extra rinse, which takes an hour (not counting time for balancing acts). Also, now that I have a pull-out faucet with a long hose on the adjacent laundry sink, I can easily add more non-dumbed-down hot water to the load.
I don't think there's any question that the above procedure is far more effective than what I could manage with the average top loader, even a vintage one that filled completely, but yes, if I had a FL machine that employed the heater on more cycles than just "sanitary" I'd be using that option regularly.
