The role of oxalic acid in cleaning

1. Remove rust
Function: oxalic acid can react with metal oxides to produce soluble compounds,

which can effectively remove rust on metal surfaces such as iron and steel.

Application: Often used to clean metal tools, pipes, machinery and equipment.

2. Remove scale
Function: oxalic acid can react with calcium and magnesium ions to form soluble salts,

which can effectively remove the scale on the surface of ceramics, tiles, glass and so on.

Application: Suitable for bathroom, kitchen, sanitary facilities, etc.

3.Bleach
Function: oxalic acid has reducibility, can decompose pigment molecules, play a bleaching role.

Application: Used for bleaching of natural materials such as textiles and wood.

4. Decontamination
Function: oxalic acid can decompose organic stains, such as ink, tea stains, coffee stains, etc.

Application: Suitable for a variety of hard surfaces, such as stone, ceramic, metal, etc.

5. Restore shine
Function: oxalic acid can remove the surface oxidation layer and dirt, restore the luster of the material.

Application: Often used for stone, metal and other materials cleaning and maintenance.

6.Disinfect
Function: oxalic acid has a certain antibacterial effect, can kill some bacteria and microorganisms.

Application: For cleaning and disinfection of health facilities.
