I recently washed my battery. The acid build-up landed on my concrete driveway. It left a rust-colored stain on my concrete. How do I get rid of this stain?? Thanks, Jerry
get a good deck wash(like behr)pour some onto the stain and scrub it in with a deck brush.let it set for awhile then rinse it off with a garden hose.use caution and read the directions on the container and wear safety glasses.it has acid in it but it works when other cleaners fail.
