...As I mentioned before, soap is based on surfactants that are designed to emulsify oils or waxes and it is a fairly old technology. No Rinse, however, is based on substantive polymers that bond and trap dirt and therefore act as a barrier to protect paint from marring. The dirt particles trapped by the polymers will flocculate and drop to the bottom of the bucket. Additionally these polymers provide greater lubrication than any soap without any foam. You can pre-rinse before using No Rinse but it is not necessary. You can also use two buckets if you like, however, it is much less needed with No Rinse than soap.
In the past 8 years, over 5 million washes have been done with No Rinse and we constantly get emails from customers who have eliminated their marring issues after switching to No Rinse. If you like a just waxed look, you can use No Rinse Wash & Wax instead! Let me know if I can be of further assistance.
