How to clean insects off a car's exterior
Soak the affected area with a hose.
Rather than blasting your car with a high-pressure stream, which could potentially damage the paint, wet troublesome spots thoroughly, then leave them to sit for several minutes. This will rinse off loose debris and help soften dried residue.
If you only have a smattering of insects stuck to your car, a light soak may be all you need to get rid of them. Apply a generous amount of car wash soap.
