Unless you've given up and let the fur cascade over your whole mouth, you, like me, have to trim the 'stache above my upper lip. Clippers are quick but....can lack the definition I like leaving, as they do, straight lines. My preferred way is to use scissors made for that purpose and while they work, hair falls on my basin but, more unpleasantly, in my mouth. I was complaining about this to the guy who does my tats and who also has a moustache and he had a helpful tip. He suggested that I take a very small bit of the Aquaphor petroleum jelly I put on new tats on both edges of the scissors. Again, you only need a very little. First time I tried this, worked as advertised. When I was through I had the shape I like and the stray bits of coarse hair on my scissors. Depending on how much work you're doing you may wish to clean it once or twice and reapplying the gel. The one thing to remember here is to remember to use a very thick gel, Vaseline and similar don't work nor do anything that has "cream" as part of the title. Hope this helps if this is a problem you've encountered.
