How did the rust on the granite come from? Due to the natural characteristics of granite, each type of granite itself contains more or less iron. There is a lot of rain in summer. When rainwater comes into contact with the iron in the granite, an oxidation reaction occurs and rust spots are formed. Similarly, the remaining steel grit during the processing, the iron tools and scaffolding during the installation process, and the decoration during the construction process and other metal-containing appliances, if cleaned or improperly used with granite cleaners, will cause rust spots on the granite surface. After construction.
Some people like to clean granite with acidic substances such as ordinary hydrochloric acid. Doing so can only temporarily remove the rust spots, not completely, and it will also accelerate the rust inside the granite, making the rust spots more serious. Therefore, the rust spots must be cleaned with a special granite rust remover to completely remove the rust spots and convert them into stable colorless substances.
Cleaning and rust removal of smooth granite
Processing material: special granite rust remover
Construction method:
1. Protect non-granite and granite cleaning parts.
2. Clean the dirt and sinking surface on the granite.
3. Mix the cleaning and rust remover and water at a ratio of 1:1 (do not dilute the granite when it is severely rusted), and apply it directly to the rusty place of the granite.
4. After all the rust has faded (it takes about several minutes to several hours, depending on the specific situation of the rust, the original iron rust spots on the granite, such as rust stone, etc., will take longer to remove the rust), and then wash with water .
5. If the rust is severe, the rust cannot be removed at one time, but the rust can be removed repeatedly.
Cleaning and Derusting of Coarse Granite
Method 1: Derust the smooth surface of granite.
Method two: (only applicable to light-colored granite):
Material: Hemp special cleaning and refurbishing agent.
Construction method:
1. Protect non-granite and granite non-washable parts.
2. Clean the dirt and surface dust on the granite.
3. Stir the granite cleaning and refurbishing agent and water in a ratio of 1:1 (the granite surface may not be diluted when the dirt is particularly serious), and directly apply to the surface to be cleaned.
4. Clean the granite surface with water for about one minute.
5. If the local rust spots are serious and cannot be completely removed after one cleaning, the above operation can be repeated.
