Recently, a friend asked what to do if the stone is yellowed after cleaning with oxalic acid, in fact, this problem is very common in the usual cleaning and maintenance, and the following will share with you some ways to solve the yellowing of stone.
Stone is a natural material that is susceptible to contamination and corrosion due to its porosity and water absorption. Therefore, when cleaning stone, it is necessary to use special cleaners and maintenance agents. If you find that the stone is yellow after cleaning with oxalic acid, you can try the following methods to solve it:
1.Use Sino 307 cleaning agent.
Sino 307 is a cleaning agent specially for hard materials such as stone, with strong detergency and permeability. When using, you can pour Sino 307 on a clean rag, wipe the yellowed stone surface, and then rinse it with water. If the effect is not obvious at one time, it can be repeated multiple times.
2.Use a professional stone care agent.
Professional stone maintenance agents can improve the surface properties of stone and enhance its resistance to stains and corrosion. When using, you can follow the instructions of the maintenance agent, and generally need to apply and care for it several times to achieve the best results.
3.Redox agents are used.
A redox agent is a chemical agent that restores the yellow substance on the surface of stone to its original color. When using, you need to operate the redox agent according to the instructions and pay attention to safety precautions. If it turns yellow during use, you can try to increase the amount of redox agent or extend the reaction time.
4.Use an acidic detergent.
Acidic cleaners can remove stains and corrosion from the surface of the stone, but you need to pay attention to the method and concentration of use to avoid damage to the stone. To use, an acidic detergent can be applied to the yellowed stone surface and rinsed off with clean water.
In short, it is necessary to use special detergents and maintenance agents when cleaning stone, and avoid using strong acids such as oxalic acid for cleaning. If there is yellowing after using oxalic acid cleaning, you can try the above methods to solve it. At the same time, it is necessary to pay attention to safety matters and use concentration to avoid damage to the stone.
