If you tow a camper, boat, or trailer you may notice your trailer hitch rusting. Prevent this with proper maintenance, regular use, and wax or paint. But if you have an existing hitch that's rusted, there are several ways to remove the rust.
Removing Rust From Chrome Hitch
If you have a chrome ball or chrome hitch that's showing signs of rust, simply ball up a piece of aluminum foil, dip it in white distilled vinegar or Coca-Cola and lightly rub the rusty spots. Rinse with warm water and dry with a soft, clean rag. Follow up by polishing with two coats of carnuba car wax.
Removing Rust from Iron Trailer Hitch
If you have an iron trailer hitch or hitch ball that's beginning to rust you can remove the rust with Naval Jelly. First, remove any loose or flaking rust with a wire brush. Then apply Naval Jelly and allow it to sit for 5 to 10 minutes—no longer than 15 minutes. Rinse and repeat if any rust still remains. Dry the metal and paint with an oil-based paint within 24 hours to prevent the return of the rust.
