Strange as it may seem, this will work. Last year, on Halloween, my car was egged. The next morning, I THOUGHT I washed it all off, but the next time I washed the car, I realized there were still specks of egg yoke on the car -- from the size of a pinhead up to the size of a pea. Since then (about a year) I have tried everything I could think of to remove the spots -- waxes, polishes, bug removers, etc. Nothing worked. I did a Google search and found this question on several sites, but no answers. So...I decided to try to find a real solution. HERE IT IS: MATERIALS: 1. a package of enzymatic cleaner for contact lenses 2. distilled water 3. cotton balls 4. paper towels 5. a syringe (about 3 cc) or an eye dropper PROCEDURE: 1. park the car in a shady spot and let the surface cool off. 2. prepare the enzymatic cleaner (using distilled water) at TWICE the strength recommended. (In other words, 2 tables per vial instead of one.) 3. as soon as the enzymatic cleaner is dissolved, fill the syringe/eye dropper with the solution 4. for small spots, just place a drop of the solution on the spot, For larger spots, saturate a cotton ball with the solution and place it on the spot. 5. Let the solution remain on the spot for up to 10 minutes, but before the solution dries, wipe it away with paper towel. You will notice that some or all of the egg will come off with the solution 6. it may take several "cycles" to remove all of the egg, but the enzymatic cleaner will eventually break down the protien in the egg allowing you to wipe it off.

The person who suggested enzymatic contact lens cleaner is on the right track. It might be expensive to clean a whole car though. I would suggest laundry detergent and water. Most laundry detergents contain enzymes to aid in the removal of protein based stains such as food and blood. Our car was egged while we were on vacation in August so the egg was REALLY dry by the time we found it. I kept the stain soaked in laundry detergent and water for several hours and it completely removed the stain.
