Many fertilisers, including some Scott products, contain iron. If you don't sweep excess fertiliser off concrete driveways and sidewalks, orange rust stains will appear when it rains or gets humid. Fertilisers containing iron may also stain the concrete floor of the garage or shed in which they are stored. Super Iron Out and CLR are two products that can help you remove Scott fertiliser stains from concrete.
