In order to check your polishing progress you can wipe down car with Alcohol, or use Menzerna's Finishing Spray as desired. Rewashing can often be done at end of polishing to assure finish is best possible for your addition of wax or sealant. I do it, often to get all the dust off the car and not trapped in wax but thats personal preference.
