What would you recommend for removing rust on concrete? I just applied fertilizer to my lawn and it left several rust spots on my driveway and sidewalk.

Many fertilizers on the market today contain a small percentage of iron. Fertilizers with iron are commonly used to create a greener, stonger lawn by preventing and correcting yellowing from iron or manganese deficiencies.

We have two products that we recommend for removing rust stains on concrete. The first is Singerman Concrete Rust Remover. This is a good solution when the rust stains cover a large area. Sold in a 22 oz. powdered concentrate, it can simply be mixed with water to form a gel that will cover approximately 60 square feet of concrete. After standing for approximately 15 minutes it can simply be washed away with a hose. More importantly it will not harm your grass or vegetation.

The second option for removing rust stains from concrete is Magica. We recommend using Magica when the rust stains are smaller or in a more concentrated area. Magica gel can be applied with a cloth or directly to the rust stains from the 8 oz. bottle. No rubbing or scrubbing is needed. When the stain is removed, thoroughly wash the area with water. Magica will not harm the adjacent lawn or plants.
