I remember watching a movie years and years ago, where this old man used Windex!
But on a serious note..........how about Sea breeze? I remember my Mom telling me to use that for acne when I was a teen. Haven't tried it myself so I wonder????
I know we're talking about AS, and thought I'd throw this out here. Pre shave, sometimes I use baking soda, and give the old chrome dome and mug a scrub down, I usually get exceptional shaves after doing this FWIW.......
