He was saying, during the polishing process, fine pieces and specs of steel wool will come off and get in the cracks and crevices of the vehicle and they will then rust (when they get wet) and you'll have a mess.
Maybe after use a good dusting with compressed air is in order.
That's what I've always done.
He also suggested using bronze wool instead.
