haha I do the same thing, using any old cup or mug to do the catching, then just washing it and putting it back into regular rotation. I... still don't really see anything wrong with it.
Any bowl with soap water mixed with vinegar will do the same. Put it near a hole in the wall and you will end up with at least a few dead in there. But again, I hate to kill, so I rarely do that. But you're right—maybe next time I'll drink enough to get over my morals. ;)
I use that line all the time:) Just wash it. That’s why we wash things. If you use soap, things become clean. What’s the big deal? But I’ve heard that Even with soap, it’s still gross retort so many times, part of me believes that too now.
