F9 Battery Acid Restoration Cleaner (BARC) is specifically formulated to remove BOTH battery acid staining AND rust stains. This includes the entire spectrum of the rust family- thin, thick, topical, embedded, and fertilizer staining. F9 BARC rust remover is easy to apply and does not require scrubbing, brushing or elbow grease. BARC is ready to go upon arrival and does not require mixing. F9 BARC chemically locks into the concrete, reversing 80-100% of the orange staining and restores concrete to its natural bright gray color.
