Their info states "pH-neutral formula lifts dirt and grime away from paint where it can be safely rinsed away " which to me seems to say just spray wash and rinse away all the dirt with out have to hand wash. Doesn't work that way. I bought a foam gun that connects to a garden hose, I've tried different ratio of dilution and even full strength in the foam gun's container. First I rinsed the car with fresh water then use the foam gun. it doesn't make solid foam that clings to the car but rather a watery foam that runs off as applying the foam. After going around the car several times "foaming" it I then used fresh water from garden hose to rinse it off. Car looked shiny but after the water dried I noticed there was still a layer of grime left behind. Second time washing I used one of those pole brushes that connects to garden hose to rinse the foam off, worked better but still left areas where I can see dirt was left behind. I bought the car 9 months ago new and have only 600 miles on it, so it isn't like it's on the road every day getting road crap on it. I'm retired and am disabled so drive it once or twice per month. Because of being disabled i was hopeing this spray foam and rinse would work as they claim but it doesn't. So looks like will still have to use sponge or something to do the actual washing after foam is applied. At least the garden hose foam gun is better then having to use a bucket of soapy water. As for the foam car wash soap i think if could find a cheaper car wash soap it will do as good a job. Re-watching the videos of this product i noticed they always use a high pressure pressure washer that uses less water per minute then a garden hose produces which could be why they show such thick foam... but also after useing foam and rinsing they also finish by hand washing. So if product is suppose to be so good why the second hand wash? Don't they know their product "pH-neutral formula lifts dirt and grime away from paint where it can be safely rinsed away"?
