YES WE CAN REMOVE RUST STAINS!!!
Rust comes from a variety of sources, mainly from metals, fertilizers and water that contain iron.
If untreated it will spread through the concrete.
We can remove 80-99% of it depending on the source and age of the stain. It is amazing!
The problem with most rust removers on the market is that they contain acids that “eat” the concrete. They strip the concrete of its cement paste and create a micro-aggregate or “etched” surface surrounding the rust or orange acid burn. When these cleaners eat the cement, they only take a minimal amount of the stain with it and cause deep, permanent damage to your concrete. Almost all other concrete rust removers formulated to remove rust will discolor the concrete, turn it white or may even turn it more orange. This is not good because now your problem is two or three fold and you have sustained permanent damage to your concrete.
