I say if you’re man enough to go with the Charles Bronson look for three decades, you’re man enough to do the job with two shots of Jack, a Bowie knife, and some Aqua Velva. Good luck, stud.
Be a real man. For hair removal tips watch The 40 Year Old Virgin.
I second the motion to use a two-blade razor over a three-blade or more. (Do they even make single-blade cartridges any more?)
I find the multiple-blade razors more comfortable for everyday shaving, but if I have more than a day or two of growth, they just seem to glide over it (and you can only get so close with scissors).
Maybe it’s because this thread is only a few days old, but I really expected someone else on the SDMB to have awoken to the fact that the double-edge safety razor is the only way to shave. GESancMan, I’d second or third or whatever the stuff others here have said: trim your stache down with a pair of scissors first, use a few passes with your usual razor to remove it, and then try to avoid constantly licking and running your finger over your upper lip for a few days.
It’s really hard for me to avoid getting on a soapbox and telling everyone who’ll listen how great a wet-shaving setup is. Badger-hair brush, high-quality cream, nice weighty razor and good double-edge blades… it’s really an amazing feeling after doing the Mach 3 thing for the first 15 years of my shaving life.
I don’t see the need to trim it first because you can’t get it short enough to matter. The razor doesn’t care if it’s 1/8 inch or a foot long. It’s always a bad idea to use a cheap razor. You will draw blood. Better to use a Gillette Mach 3. You don’t the newest version of it but the basic vibrating blade system will be a huge improvement over a standard blade.
I just shaved my mustache after 30 years and my upper lip was much more sensitive to shaving than any other spot and still is to some extent a month later. An even more important reason not to use a cheap razor.
Too modern for me. I learned with a straight razor and while I have tried electric, safety and double-bladed I keep going back to that old “Cossack Butterknife” of mine.
After getting the stache off consider treating the skin under it as you would a light sunburn for a while - some lotion or medicated powder at night until it weathers in a little. And if you are somewhere sunny use a clear sunblock for a week or so. First time I dropped mine after having it for 35 years, I got a nasty burn just over my lip that gave me a very strange look almost like I had been branded.
Everytime there’s a thread about shaving someone jumps in with “take it to the shower.”
I’ve always had great eyesight… until I hit 40. Then my eyesight went to hell in a handbasket.
So… while shaving in the shower was a great idea when I was younger… I don’t think I can wear my glasses in the shower. Shaving in the shower is out for me. 
I’m blind as a bat, but I shave in the shower purely by feel.
Thanks for the replies, everyone. Still haven’t worked up the courage to do it.
As for my hair: no mullet here. It’s long all the way around. 
Yup. I’m blind as a bat as well, though a bit younger. But shaving in the shower is just so much cleaner and easier.
Scrape, then feel. If it’s still prickly, scrape again.
I haven’t shaved in front of a mirror for years. I cut myself maybe thrice a year; I always look fine (once I get out of the shower, towel off, put on the glasses and inspect in front of the mirror).
My sweetie is the same way about his set up; he even got his dad into it, and THAT was a tough sell. I think part of the ‘fun’ is the ritual; perhaps by simply taking more time with it, it’s a better job all around than swiping the face and expecting the razor to do most of the work.
That being said, no thank you to the same setup for me and my legs. :eek:
p.s. Shaving legs and other stuff in the shower when you’re blind as a bat is also ‘fun’, for a given measure of ‘fun’. 
I wonder if the OP will have a paler area when his stache is shaved?
I wound up ignoring the advice given here - once I worked myself up to it, I just did it; if I’d gone out and bought a mirror and a better razor I probably would have talked myself out of it. 
One of my double-bladed disposables did the job just fine, with no pre-trimming, in about ten minutes. It’s only been about six hours, but so far there’s been no irritation or anything. My lip feels a little cold, though.
I keep getting up and looking at myself in the mirror, and I think I look better. I should have shaved a long time ago.
Now the next step is going out in public and enduring the comments from people I know… the main reason I’ve dreaded doing this.
Congratulations! Goodbye, '70’s, hello 2010’s! Next, we’ll get to work on updating the 'do. Practice on it here.
Hey, to you guys who shave in the shower by feel; do you use shaving cream? How do you handle the sideburn area?
