I have a relatively new car with nice clean paint. I've read and been told that cleaning bugs and bird debris off of my car quickly is important because it can damage the paint.

Do I really need to wash it off quickly?

Can it really damage the paint?

Yes, you should try to remove it as soon as possible.

When a bug is smashed into the front of your car all of its guts are allowed to mix together. Most bugs will result in an acidic goop that sticks to your car. You can see it on your windshield, but you won't see it very well on your front grille until the damage starts to accumulate.

This acid will etch and scrape into the clearcoat paint, then eventually it will work its way deeper and cause deep damage. This kind of damage can only be properly repaired by a paint shop.

Similar reactions happen with bird debris. The goop will sit and etch into the paint, causing weakening of the clearcoat.

Here's an example of what happens if you leave bird droppings too long:bird damage

In order to have long lasting paint that looks good, it is important to get any damaging material off of the paint quickly. With modern bug and tar remover products available at your local auto care center the job shouldn't take more than a few minutes.

    I don't think that linked answer is a good one: using sandpaper to remove a bug sounds like crazy talk

    I definitely agree with @BobCross ... I'd remove the link, or make sure it's pointed to "mikes" answer. Three or four of the "accepted" answer's suggestions are plain crazy talk I tell yah! Oct 19, 2015 at 23:17
  • Agreed, I had only skimmed the top answer when I first added the link. Hopefully someone can provide a nice clear answer somewhere for how to remove bug gunk.
