My car battery was slowly leaking acid on my driveway for days before I noticed it. The concrete has turned a deep rust color and I can't get the stain out. I tried scrubbing it with laundry soap and a wire brush but no luck, I think I may have to chemically bleach the stain or I was thinking about sand blasting (but I'm not sure how deep the stain penetrated the concrete).
The driveway is 2 years old and was never sealled when it was poured.
