just wanted to drop my 2 cents by but as far as using dish soap on cars I personally would NEVER use it simply wash a car. Dish washing soap contains strong detergents that strip off any protective wax off from the clear which in turn exposes the clear to the elements (UV rays, bird crap and so forth), which over time is EXTREMELY harmful to your cars paint job. Now if thats what your goal is and your planning on using cleaner wax to remove oxidation and so forth with the intentions of waxing it after than thats another story. Basically DO NOT use it unless your going to wax it after!!!!!
