What is important, however, is that the acid levels in carnauba aren’t so great for your car’s paint. The majority of your car wax is filled with emulsifiers and stabilizers to control the carnauba’s pH to be as close to 7 (neutral) as possible. What this means is that while the wax is in the jar, all is well. Take the wax out of the jar, apply it to your paint, remove excess, and watch it shine… then there’s a slight problem. The longer the wax stays on your car, the more acidic it gets – the stabilizers diminish from being exposed to the environment (sun, water, etc.) and you’re left with a somewhat acidic substance “protecting” your paint.
