My husband was trying to be nice, and pull my car into the garage for me. He slipped the clutch, and my car jumped into the side of the garage door leaving house paint on my bumper. My car is yellow. How do I safely get white house paint off the bumper without damaging my paint?

Using a soft cloth with many of the cleaner-polishes on the market might work. First try soap and water, since most house paints are water based latex products.

Good 'ole car wax and elbow grease. Ruba-dub-bub, babe. Second thought, put that hubby to work. He did it!!
Next get an automatic, preferably a nice blue, or maybe a firethorn red.

Regards. :)
