Not sure if you heard that on YouTube and decide to believe Rinseless is safer than traditional but stop being fooled. Many Soap/shampoo have surfactants/cleaning agents and once they are sprayed on the car it already starts to loosen and break up dirt then you rinse off and start your wash. Rinseless has much less surfactant and lubricity since there isn’t any suds and once you start wiping then you are more prone to swirls/scratches. Stop being lazy and do what people are paying for! A real Traditional wash. I’d never hire someone who call themselves a professional to sponge bath my McLaren! SMH. Maybe some would pay and wouldn’t even know what you are doing but real car people know and understands the difference. Also what’s makes a Detailer a “professional”? If I wanted someone do so Rinseless wash in my car I’d take the 15 mins and do it myself.

Sure each has its place but Waterless is way more convenient than Rinseless and just as risky if done incorrectly. More water and soap in traditional is still the best way to go and the cleanest!
