How do i clean rust from under my car?

Answer 1

Prevent rust by keeping the underside of your car clean also. Place a lawn sprinkler under your car and turn on full blast. Move occasionally so it will reach all areas. This is a good way to remove all salt and road grime. If you chip the paint on your car, clean promptly and apply touch-up paint or clear nail polish to the area.

If the carpet in your vehicle is subjected to a lot of salty water over the winter, rust could be forming where you can't even see it, underneath the carpet. A good rug shampoo, either a do-it-yourself project or professionally done, will help remove the salt from the carpet fibers. Be sure to clean the upholstery too.  

Answer 2

id use a drill and one of those bits that has a wire wheel on it

Answer 3

If there are no holes in the floor or structural members from  the rust, take a wire brush and scrub the rust. After the loose stuff and dirt are gone, take POR15 and brush it over the rust. You can get this in a pint. Make sure you wear gloves because this stuff  will stain your hands for a long time. Try to let it  dry for 24 hours before driving it so it doesn't sling onto something you don't want it on.  

Answer 4

Rust is called CANCER OF THE METAL - because no matter how your grind them away they always come back.

You can try to grind it away, but to do a permanent job, you have to cut them out - and replace the metal piece.

Good luck...
