Handlebar Mustache vs. Straight Razor

[MisterMoo]

I used to carelessly ding a handful of mustache handlebar hair about once a week. At one point I finally cut off the ends thinking a too-thin handlebar was worse than none at all. Rookie stuff. Thing is, prewash the face and mess a little soap into the handlebars and I have a slippery mess. I can't prewash without taking off most of yesterdays wax; neither can I lather my face without adding a little soap to mustache ends. However I do it, the stache usually ends up limp and hanging in the free-fire zone at shave time. I have taken to grabbing a handful of handlebar and holding it clear while the razor does it's work but, this way, I end up with soapy fingers a couple of times during a shave. I hate that.

Any advice to a chronic mustache handlebar chopper? Wiping off soapy fingers isn't the end of the world a couple of times per shave but, still, I feel like there is a code to be cracked which has so far evaded me. I admit it has been many months since major accidental mustache chopping on one side or the other but I hate the soapy fingertips.
