Don't you guys still trad french windows and sliding patio doors? I do. Hand prints don't come off with pure water, its the only thing it won't shift.

Ahh, you just have to watch carefully, so long as you spot the offending marks a bit of extra scrubbing will get handprints off no problem.
I cope with it on the plate glass of shop windows all the time, in fact, the thing that tee's me off most of all is women who snog pub windows!!!
lipstick is a sod to shift
People who bleed on shop windows after they've bean beaten up also bug me...no consideration some people
Kebab gunge is hard to get off with WFP too, vomit isn't too bad, at least with WFP you can clean it at a distance of 6ft! And use the edge of the brush to shift stuck on lumps
For those of you that don't do shops, you won't have had to scrub off 'Green Gilberts' with your applicators...always made me gag...at least with WFP that's easy to get rid of too
