I have to say that Optimum No Rinse is a really slick piece of chemical engineering. It does exactly what it says it does, just follow the directions. And here is one of my all-time favorite YouTube videos, giving you the directions in the first 1 minute and 40 seconds, but keep watching until you see the end:
ONR and The Big Red Sponge - YouTube
It's really that easy and simple to do. (Yvan LaCroix does not waste a syllable or a gesture.) The Big Red Sponge is available from Opti-Coat.net. Optimum also offers the Opti-Mitt, another sponge applicator. I prefer the Big Red Sponge. The Opti-Mitt is great on flat, horizontal surfaces, but it looses a lot of its ability to hold onto the ONR solution when washing a vertical surface.
The sponges are not necessary for washing, but they rinse easily and reduce the amount of really dirty microfiber laundry. Tesla Service uses only 16x16 inch micofiber towels for washing with ONR, yellow for the upper half of the body, and blue for the lower, dirtier half. Fold the towels in half along both axes so that you have 4 cleaning faces on each side of a towel. (Larger towels make it harder to keep track of where the clean faces are and harder to stabilize your folds.) As you move one face across a dirty panel, the leading edge will turn dark with dirt. By rotating your hand, you can lift the leading edge of the towel off the panel, so that the dirt is more evenly distributed across the width of the face. (YouTube has videos on how to rotate your hand as you move the towel through a cleaning stroke on each face.) The Tesla techs know how to do this well and fast, leaving no swirls when you get one of those great ONR service washes. IIRC, Tesla uses the one bucket wash method with a grit guard, using clean towels as needed.
I'm old and less coordinated than the Tesla techs, so I follow Yvan's method with the Big Red Sponge. I use 16x16 microfiber waffle-weave towels for drying. Wiping a clean surface is a lot easier and less dangerous than wiping a dirty one. TheRagCompany.com.
By the way, the techs know all four ONR dilutions and make them up at each Service Center:
1. Undiluted as a _really_ great tar remover. Apply directly to tar, let it stand briefly, wipe tar off with microfiber towel.
2. 1:8 as a detailing spray
3. 2 oz ONR into 1 gallon of water for a clay bar lubrication
4. 1 oz ONR to 2 gallons of water as a car wash solution
This is an Arthur C. Clarke moment: ONR is a technology advanced sufficiently to appear to be magic.
