To lubricate lock cylinders, apply graphite lubricant sparingly through the key slot. Insert the key and operate the lock several times to be sure that the lubricant is worked into the lock cylinder.
At least once a year, use a multi-purpose grease to lubricate the body door hinges, including the hood and fuel door hinges and latches. The glove box, console doors and folding seat hardware should also be lightly lubricated. Open and close the door several times to be sure that the lubricant is evenly and thoroughly distributed.
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. Clean leaves from vent and cowl areas.
To preserve the appearance of your car, it should be washed periodically with a mild soap or detergent and water solution. A detergent specifically designed for automotive use should be used to loosen dirt or grease from the vehicle. Dishwashing detergent contains degreasers which will strip the vehicles surface of wax. Only wash the vehicle when the metal feels cool and the vehicle is in the shade. Rinse the entire vehicle with 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 polishing and waxing will remove harmful deposits from the vehicle's surface and protect the finish. If the finish has dulled due to age or neglect, non-abrasive cleaner may be necessary to restore the original gloss.
