Never use dish soap to clean a car as most of them have detergents that will eat into a car’s clear coat.

Even though the detrimental effects of using dish soap on a car have been proven time and again, people still use it in a pinch, often with irreparable results. Many of the detergents and degreasers in the common bottle of kitchen soap will eat into a car’s clear coat, thus causing premature fading and corrosion.
Paint job issues are an expensive fix. And because car cleaning supplies are sold at every grocery chain and dollar store out there, taking a quick trip down the street remains a sensible solution when a big bottle of dish soap is the only thing on hand.
