On reading the splashes on windows -
This is not a general solution, as I believe in taping up/protection . An ounce of prevention is worth a pound of cure and all that.
Anyway,
When working to a surface where masking up is not practical, s spray of WD40 or vegetable oil will stop stuff sticking to the surface, and you can then wipe clean.
We first started doing this on metal frames in Police holding cells, where there were 2 sbr/opc slurry coats and three coats of sbr render applied. As coats had to be left for a while, and the tape removed after each coat, we found that WD40 worked better. I sometimes use a spray of vegetable oil on door/window frames when plastering as they clean more easily, but as I said above - taping up etc is best for most things.
