I don't think you need to use dish soap to remove the wax, this idea was started by zaino. I just wash my car using zaino soap. But it probably won't hurt the paint if you do use dish soap. When you clay be sure to spray a mixture of car soap and water as you clay, don't just spray and start claying. If you're going to clay the car I recommend you buy a porter cable polisher, it will make it easier and quicker to remove any scratches you create after claying and also the swirl marks the dealer made. There is a ton of info on this forum and online how to get things done.
