Oh, so common.
I believe the answer is what I have done. Prior to moving in, when the garage floor was completely bare, from side to side, I rolled out thin indoor-outdoor carpeting. I cut it exactly to the ends, and it is excellent. Once a month or so, I vacuum it (since the vacuum is in the garage anyway), and it looks great. Haven't had a problem, and if you saw it (and you're welcome to), you'd agree.
