You can either use the rust detergent you put on clothes, pour very cheap dark wine on the rust, or make a mixture with bleach and other detergents.

Rust stains can be removed from concrete using mild acid, and many people have found success using fresh lemon juice or undiluted white vinegar. Spray either of these on the stain and let sit, then rinse. If the stain persists, head to your hardware store for a chemical rush remover containing oxalic acid. Be careful, as it is very toxic.
