How do get turtle wax out of rags

After buffing my car with TurtleWax and new rags, I washed the rags in the washer. When I went to use them again, I noticed they were leaving streaks that weren't there when they were new. I can only surmise that machine-washing them did not get the Turtle Wax out entirely.
