I was bored last weekend and decided to see what would happen. I took some QEW and then mixed it into a spray bottle. I say about 1/8 of inch to the rest of the bottle of water. Sprayed down the car, then rinsed on the mist setting on the hose. I notice a lot of the dirt washed off. I did a reg car wash afterwards just to be sure. I thinking maybe this way I am reducing the chance of large dirt scratching the car and making the mit dirty. (Sometimes no matter how hard I clean it, it still a little dirty). I didn't use very much of the bottle. I think I still have about 3/4 of the spray bottle left. Am i wasting QEW or Car soap. Anybody else tried this?
