Like Rich says, what you are felling is the adhesive oozing out from the fanric of the vinyl itself. You will scrub until the cows come home. You just may get it "clean" for a little while.
One common sense thing to remember is that if you do ever get it clean, what has happened to the adhesive then?
Clean off any dirt or bugs and solve the problem by "encapsulating" the adhesive with some Future floor wax. Don't overthink this.
