Let's just say my 8 year old kid if I had one could do a better job. It was quick and convenient but the job was half ass. If you don't have time to do it yourself or pay a detail company I would use this as a quick fix or as a pre-clean before you ckean it yourself. My rims are still covered in soot and oil, my windshield has streaks, and the front seat still has something spilled on it and down the crack.
