isn't diluted car wash soap. It's concentrated. You wet the vehicle, apply one or 2 squirts to a body panel, and then use your mitt to wash the vehicle in the regular manner.
The water on the vehicle dilutes it. A real advantage is you don't use too much soap (a common problem for most folks), and you don't need a bucket full of water.
I've used the product for 3 years now - one testing and 2 years of use. I find it's about 15 minutes faster per car than the bucket method of washing, since you're not constantly going back and forth to the bucket for your mitt. It also saves my back from so much bending over. I hang the bottle on my pocket with the trigger to keep from setting it down.
It's also great for pretreating caked on bird droppings, so you don't scratch the paint.
If you could get the consistency of any car wash product right, you could do the same thing is a spray bottle.
Obviously, it's not for the double throw down detail. For for a quick, everyday wash I think it's great. One problem you will find is the need to reverse rinse/flush the mitt out to remove contaminants.
In testing, we were able to wash over 50 vehicles with one 16 ounce bottle. (Disclaimer - this was typical SoCal slightly dusty vehicles. I'd expect 20-25 vehicles in more "real world" conditions, but that's still better than using 1 oz of car soap per gallon of water in the bucket method, which would be 8 or so buckets of car wash, assuming a 2 gallon fill in a 3 gallon bucket. Of course, your mileage may vary.)
) and my rinse bucket at least 5 times at most 15 or so times, so I have plenty of chances to put fresh clean suds on my car.
