This is a unique gel formula cleaner used for removing rust and iron oxide-based stains from surfaces, both internal and external.
It was specifically formulated to safely dissolve rust stains left by metal garden furniture, leaking heating systems and grass fertilizer overspray. Rust Off has a unique colour marker that causes the gel to turn purple when it comes in contact with rust / iron oxide so you know that it is working to break down and dissolve this type of stain. It is also very effective at removing iron oxide blooming that can occur naturally in some types of natural stones ie granite, marble and travertine. It is ideally suited for use on a multitude of surfaces, an extremely effective and popular product.
