Remove Offgas on Windshields

So you’ve cleaned the exterior of a client’s ride, but why is it still greasy or hazy looking? This may be due to ‘offgas’ which is basically a process in which the sun vaporizes the plastic on a car’s dashboard, causing it to evaporate and stick to the interior windshield as it cools.

Offgas usually happens on newer vehicles, but can be removed by cleaning the inside of a client’s windshield with Super One glass cleaners. You may have to agitate a little more than normal to remove it.
