How to Remove Rust from Concrete
Removal Method

Scrub with a stiff wire brush.
3
Rinse with clean water. For stubborn stains, apply a paste of lemon juice and borax, let sit 30 minutes, scrub, rinse.
💡 Alternative Method
Muriatic acid (diluted 10:1 water to acid) for severe rust on concrete. Requires full PPE: goggles, gloves, respirator, and outdoor ventilation.
