Quartz cleaner: Does oxalic acid wash stone work?

The acidity of oxalic acid is relatively weak, and the resulting calcium oxalate is also insoluble. It is not recommended to use oxalic acid, which simply oxidizes and reduces rust (Fe2+).

Sodium carbonate can only wash off excess oxalic acid, but sodium carbonate, a substance formed by the reaction between oxalic acid and stone, cannot be washed off.

It is recommended not to use oxalic acid for cleaning, because oxalic acid is unstable, its solubility is too high, and it is still a strong acid. Even if it is cleaned off, it will come back later, and it cannot be eliminated from the root cause, like SINO306 marble and granite.

Oxalic acid is a complexing agent, and its function is a reducing agent and a bleaching agent. Generally, it is used to clean the stone with alkaline substances, such as precipitated calcium and magnesium ions, and the surface attachments of the stone are basically silicon and calcium substances, and PH test paper can be used. Measure the acidity and alkalinity of the stone skin. If it is alkaline, you can soak the stone in a 3% oxalic acid solution and observe the reaction. The general alkaline rust sand bubbles can be removed.
