How to Remove Rust Stains

Rust Stains in concrete can be caused by a variety of reasons. Every rust stain must be investigated to determine what caused the stain. Once the cause has been determined, then the correct method and application for removing the rust stain can be applied. The sooner we can get to the rust stain after it has formed the easier it will be for us to remove it. So, when we are asked How to remove rust stains we often answer that we really need to see them first. Rust Stains can be caused by irrigation systems, fetrilizer granules, battery acid, metals, and a host of others. A local Church here in Houston Texas recently called Clean and Green Solutions to remove some rust stains they said were caused by battery acid from a leaking golf cart. We were told the rust stains were little drops all throughout the concrete. We found that the Church had Rust Stains actually caused not only by battery acid from the Gold Cart, but also, from fertilize granules that were applied with the use of a fertilizer spreader. After applying the fertilizer, the surrounding concrete was not swept or blown off properly, and the granules were left on the concrete. Once the irrigation system was turned on to water the grass, the water and the granules caused the rust stains you see here. Rust caused by Fertilizer Granules will always have a small round circle with a bleeding or running drip look that runs away from the granules in the direction that the water drains. Inside the circle you will see a small cleaner spot that was caused by the granule sitting there and not moving while it was wet. The battery acid rust stains are much larger and are congregated in a specific area where the golf cart sat. Both of these types of rust stains are the hardest rust stains to remove. With the right cleaning equipment and cleaning solutions, knowledge and experience the concrete can be restored to it’s original condition. The use of a pressure cleaner, pressure washer , or any other high pressure cleaning equipment in the wrong hands can cause damage that can not be repaired. The damage caused in this concrete can not be repaired and was performed by someone with out the proper knowledge and experience to operate the equipment. This concrete is fairly new and should never have had high pressure applied to it as it caused the top coat of the concrete to be removed.
