What to do if rust appears on the granite surface?

Golden hemp is a commonly used granite stone. This granite has dense structure, hard texture, good acid and alkali resistance, and good weather resistance. It can be used outdoors for a long time. However, during use, due to water soaking, oxidation and other reasons, golden hemp may appear rusty, which affects the decorative effect. So how to deal with this kind of rust spots?

1. Try to avoid using acidic cleaners to directly clean the rust spots on the stone surface. Because some acidic cleaners simply oxidize and reduce the rust spots, the oxidized and reduced iron ions are still unstable and easy to contact with the air again. The oxidation reaction of water and oxygen regenerates rust, and the golden granite will further expand the rust area with the flow of acid solution. This is why the rust spots will be removed more and more when using acid cleaners to remove rust.

2. When choosing the rust remover, the golden granite must choose the products of the manufacturers with better reputation and quality. A good rust remover contains an appropriate amount of additives in addition to acid components to maintain the stability of iron ions in the oxidation-reduction reaction. The rust spots of the golden granite granite treated with this rust remover are not protected, and the effect can be maintained for a long time.

3. Because the basic chemical composition of marble and granite are different, the main component of marble is calcium carbonate, which is alkaline; the main component of granite is silica, which is acidic. Therefore, when choosing a rust remover, golden granite must be distinguished between marble rust remover and granite rust remover. Granite rust remover must not be used for the rust treatment of marble. Marble rust remover cannot be used for granite. The rust spot treatment.

4. When dealing with rust spots on the surface of the stone, you only need to apply the rust remover to the surface of the stone evenly. Golden granite can also be treated by surface grinding and polishing; the treatment of deep rust spots is relatively more complicated, requiring a certain amount and reaction time, and sometimes needs to be reused.

Granite is a kind of stone commonly used in daily life. Because of its strong hardness and good structure, it is especially suitable for long-term use outdoors. However, if it is left outdoors for a long time, due to bad weather and many reasons of dampness, some embroidery will appear. Traces greatly affect the visual effect.
