A car's paint job receives a glutton of punishment from the sun's rays, chips from gravel and even water. Metals and minerals found in water supplies leave behind a residue when left to dry on a car's surface. When the car is left in the sun the sun bakes the residue right into the paint. Rain that contains air pollutants can also damage a car's paint job. Fortunately, eliminating water spots already on your car's paint is not difficult.

Step 1

Wash the dirt off your car with a bucket of warm water mixed with two or three drops of dish detergent. Wipe the car down with the sudsy water and a large sponge.

Step 2

Rinse the car with a garden hose. Remove all soap residue from the car paint.

Step 3

Mix ½ gallon of distilled water with ½ gallon of white vinegar. Sponge the mixture on one section of the car such as the hood or the car door.

Step 4

Allow the mixture to sit for 30 seconds, then rinse it off with the hose. Repeat sponging on the vinegar solution one section of the car at a time and rinsing off. Rub harder on water spots that are baked into the paint.

Step 5

Re-wash the car with the dish detergent and warm water and rinse thoroughly. Dry the car with clean towels or rags.
