One: acid attack

The slight infiltration and erosion of the micropores of the stone by the acidic substance are more obvious for the marble stone.

Two: pigment contamination

Generally fruits and beverages come with natural or artificial colors, which are difficult to clean when they penetrate into the stone. The micro-corrosion causes the surface of the stone to become rough for a long time, and the acid pigment is easy to cause the surface of the stone to yellow and darken.

Solutions:

1. Just contaminated

If the stone has just been contaminated, it must be cleaned up immediately.

2. Moderate penetration

If it has been dyed or caused a yellow or dark surface, it can be cleaned with a neutral stone cleaner.

3. Deep penetration

Assuming that the neutral stone cleaner still cannot be removed, it is recommended to use the rust removal method and the pigment paste mixed dressing to remove it. The method is the same as that of the cream cleaning agent to remove rust. When the pigment is removed, remove the dressing and use Wash with clean water and dry, use a protective agent to maintain.

4. The surface is eroded

If the surface of the stone has been eroded and rough, tarnished, you can use polishing powder to polish again, and then apply a stone protection agent to treat.

5. Serious damage

If the damage is serious, ordinary cleaning methods can not help you, please ask a professional stone maintenance company to handle it.
