Squeaking Brand new squeaking

I imagine if 106 people have responded then at least one may have asked if the squeak is coming from the wheels. I see it every week under warranty. the ramps and wheels need time to wear a little and until then they can be hideous. its counter intuitive being as that the ramps and wheels are supposed to be cleaned all the time. BUT, when new they make a racket and the easiest way to shut them up is a to rub a bar of soap on the ramp where the wheels travel. it shuts them up and holds a little dust over time to wear the shine off the wheels and make them act as they should. Beyond that I would need to know where the sound was coming from if not there.
