I'm just curious, because I don't. It seems to leave a bit of powdery/salty film, but it goes away once I apply my post-shave Nivea Sensitive. Wondering what everyone else out there does.
I leave it on my face for 30 seconds or so while I wash out my brush or scuttle then wash it off.
^^^^ This is what I do.
And also pointed earlier I use it to judge the quality of my technique. I don't use it all the time, I use witch hazel.
I wash it off with cool water after I clean my razor and brush.
