Detailing your vehicle may improve the cabin's air quality as well as the overall performance of the vehicle. The first step in the process is removing floor mats, seats, and anything else that can be easily and safely removed from the car's interior. It may also be a good idea to remove the wheels before thoroughly cleaning them.
Be sure to rinse the car before you apply soap or water to ensure that you remove as much dirt, grime, and debris as possible. Waxing your car after cleaning it can help to protect the paint from being scratched or from fading after spending time outside.
Finally, be sure that you spray oil on hinges and other components that need to be lubricated to work properly. If you feel comfortable doing so, it may be a good idea to change the engine oil or filter while detailing your vehicle.
