At least once a year, use a multi-purpose grease to lubricate the body door hinges, including the hood, fuel door and trunk or liftgate hinges and latches. The glove box, console doors and folding seat hardware should also be lightly lubricated. Be careful not to stain the interior fabrics with the grease.
The door and window weatherstripping should be lubricated with silicone lubricant. Flush the underbody using plain water to remove any corrosive materials picked up from the road and used for ice, snow or dust control. Make sure you thoroughly clean areas where mud and dirt may collect. If necessary, loosen sediment packed in closed areas before flushing.
To preserve the appearance of your car, it should be washed periodically with a mild soap or detergent and water solution. A liquid dishwashing detergent that DOES NOT contain any abrasives may be useful in loosening dirt or grease from the vehicle, while not endangering the finish. Only wash the vehicle when the body feels cool and the vehicle is in the shade. Rinse the entire vehicle with cold water, then wash and rinse one panel at a time, beginning with the roof and upper areas. After washing is complete, rinse the vehicle one final time and dry with a soft cloth or chamois. Air drying a vehicle, by driving at highway speeds for a few miles, may quickly and easily dry a vehicle without the need for excessive elbow grease.
Periodic waxing will remove harmful deposits from the vehicles surface and protect the finish. If the finish has dulled due to age or neglect, polishing may be necessary to restore the original gloss.
