Stone rust treatment skills

Treatment Techniques for Stone Rust Stains:

Rust stains on stone surfaces can be caused by two main factors. Understanding the root cause is essential in choosing the right cleaning and prevention method.

The first type of rust comes from iron naturally present within the stone itself. Most natural stones contain trace amounts of iron, which can react with moisture—especially rainwater—to form unsightly rust spots over time. These types of stains are often stubborn and difficult to remove. A specialized product like Kelin KL608 Strong Rust Remover is recommended, as it has strong penetrating properties that can reach deep into the stone’s pores, ensuring a thorough clean without damaging the surface. Avoid using harsh chemicals like industrial hydrogen peroxide or strong acids, as they can worsen the problem. After removal, it's crucial to apply a protective treatment to prevent water from seeping into the stone and causing future rust formation.

The second type of rust comes from external sources, such as leftover steel sand during processing, metal fixtures used in construction, or decorative elements made of iron. These types of rust stains are usually easier to remove, and products like KL308 Rust Remover can be effective. However, once the stone is installed, removing rust becomes more challenging due to accessibility issues. That’s why applying a protective coating before installation is highly recommended. Once the stone is in place, especially on exterior walls, it becomes harder to treat and may be exposed to acid rain or other environmental damage. Therefore, proactive protection before installation is always the best approach to prevent rust and dirt buildup in the long run.
