Over on "that other detailing board", I kinda have a rep for my incredibly OCD "touchless car wash" method. In a nutshell, when my car is really dirty:
High pressure rinse. (John Deere gas powered pressure washer)
Foam cannon using Chemical Guys Citrus Wash & Gloss
High pressure rinse. (using a CRSpotless so I don't have to touch the paint to dry it)
Normally, the above steps are all that's necessary to get my car completely clean. That is, until the LSP starts to fade a bit. If that happens, I follow up with another round of foam, brushed off gently with a long hair boar's hair brush. If stuff still remains on the paint after that, I ONR it.
My car seldom gets that dirty nowadays, so most of the time I just ONR it. But on the occasions that it gets too dirty for me (in my mind, anyway) to just ONR it, I use the above technique. The reason I have been dedicated to the CG CW&G is that it has a fairly high concentration of detergents, and not just lubrication agents. It seems that most of the car soaps on the market now days are nothing more than lubrication in a bottle. I need the chemical cleaning, since there just isn't any mechanical agitation in this process.
So this all (finally!) leads up the question: Does Optimum Car Wash have much in the way of detergent action, or is it pretty much just lubrication for a wash mitt? I know it's a fine line to walk; too much detergent in a car wash = removing the LSP, while not enough leads to dirty cars. And since the majority of car washers use some sort of wash mitt, lubrication becomes the focus point of most car soap makers.
I've literally spent hundreds of dollars on different car soaps, trying to find one that has a decent amount of detergent that can be diluted down to where you still get detergent action without stripping the LSP off. Unfortunately, I never gave OCW a try. CG's quality control has gone down hill *a lot*. The last several gallon jugs of CW&G I've bought have been terribly inconsistent. So I'm looking for a replacement.
I've been using the above car wash method (and variations on it) for years now. I've been able to keep my two cars *completely* swirl free with this technique. On my own cars, polishing is a thing of the past, although I still can't help but see if I can't amp the gloss "just a bit more" quite frequently by using various finishing polishes, but this is simply to enhance gloss, never to remove swirls.
