Ah, yes , the best wash soap/ best car wax saga continues!
I will throw my two cents worth of opinion for Meguiar's Professional No.62 Carwash shampoo and conditioner. I have used this shampoo in the past after reading somewhere (probably Meg's website) that it was used at a well-known car museum for their collection, so I figured it had to be good for my daily driver. Before this, I had been using whatever I could find OTC. Like many of you I have used Meg's Gold Class and before that some citrus-base soap that came from Big Lots (Don't laugh! it cleaned very well.) While No.62 is relatively expensive compared to OTC soaps, it lathers and suds very well, but the big thing is it rinses clean. I bought a gallon of Optimum's Car Wash (OCW) AND 32 oz. No-rinse (ONR) when I ran out of No.62 based on the reviews I read from Detailed Image and within this forum. Like many of you, I found it does not rinse as clean as No. 62, for whatever reason. Cleans very well and the suds lasts, but the" film" it left behind on windows meant I would have to clean the windows with a window cleaner to see out of them decently. Maybe it was the water and yes, like many of you, I mixed ONR with OCW soap to supposedly "soften" the hard water when I washed vehicles for friends and family at their house. But at my home that has a municipal water supply that is not that hard and using just OCW, I still got film streaks on my windows. So I bought new gallon of No. 62 with about a 1/4 gallon of Optimum Car Wash left. Still will use OCW, but for maintenance 2-bucket traditional car washes, I prefer No.62
