Rust stains on your driveway are not only unsightly, they reduce the curb appeal of your property, and therefore, its value. However, most rust stains can easily be removed from concrete driveways in just a few simple steps using a combination of natural or commercial rust cleaners or the help of an expert. Follow these easy tips to help you get rid of rust stains on your driveway.
When tackling your driveway's rust stains, start by using soap and water on the affected areas to remove any grease or dirt that may prevent acidic cleaners from working effectively. Any soap that cuts through grease will work, so regular dish soap should be all you will need. Also, take your driveway's finish into consideration before you begin applying the acids. If your driveway is painted, you will want to dilute any acidic cleaner with one-part water and use a brush that does not strip away the paint. A wire brush is ordinarily recommended for concrete driveways without paint.
Natural solutions work best for minor rust stains and can remove them with one or more treatments. Lemon juice and white vinegar have highly acidic natural compounds that break down rust and eliminate the reddish orange stains found on driveways and other concrete surfaces. Undiluted application of each may be required to remove the stains as you allow the area to soak for a minimum of 10-15 minutes; however, if your driveway is painted, you'll want to dilute these acids before application. Then, you can begin scrubbing with a noticeable difference occurring after your first rinse.
Major rust stains can be more challenging to eliminate and usually require stronger acidic solutions for their complete removal. Common commercial rust cleaners use oxalic acid, trisodium phosphate and hydrochloric acid, which need to be diluted before they are applied to the rust stain. If you choose to use hydrochloric acid, be careful not to leave it on for too long as it can turn your concrete blue. Follow the same procedure for these cleaners, reducing soak time to 5-10 minutes, and be sure to wear protective eyeglasses, gloves and clothing that protects your skin when handling these acids.
