Are degreasers suitable for cleaning stone surfaces?

Degreasers are chemical cleaning agents specifically designed to remove grease, oil and other organic contaminants, and are widely used in industrial, household and commercial cleaning fields. However, for the cleaning of stone surfaces, the use of degreasers needs to be particularly cautious. As a natural material, stone has unique physical and chemical properties, and inappropriate cleaning agents may cause irreversible damage to it. This article will discuss in detail whether degreasers are suitable for cleaning stone surfaces, analyze its potential risks and alternatives.

1. Characteristics and cleaning requirements of stone

Stone is a naturally porous material that can be divided into two main categories: natural stone (such as marble, granite, limestone, etc.) and artificial stone. Each stone has different chemical composition, hardness and porosity, and therefore has different tolerance to cleaning agents.

1. Sensitivity of natural stone

Natural stones such as marble and limestone belong to carbonate stones, the main component of which is calcium carbonate (CaCO₃), which is easily corroded by acidic substances. Although granite has a high hardness, long-term exposure to strong acid or alkali environments may also cause surface roughness or discoloration.

2. The porosity of the stone

There are tiny pores on the surface of stone, which easily absorb liquids and pollutants. If the wrong cleaning agent is used, it may penetrate into the stone and cause permanent damage.

3. Decorativeness of stone

Stone is often used for decorative purposes such as floors, countertops, and walls, where surface gloss and texture are important values. Improper cleaning agents may cause the stone surface to lose its gloss or become spotted.

2. The composition of degreasing agent and its influence on stone

The main ingredients of degreasing agents usually include surfactants, solvents, alkaline or acidic additives, etc., which are used to achieve the cleaning effect by dissolving or emulsifying grease. However, the impact of these ingredients on stone may not be ignored.

1. Surfactants

Surfactants are the core ingredients of degreasers, which can reduce the surface tension of liquids, making grease easier to remove. However, some surfactants may remain on the surface of the stone, causing discoloration or loss of gloss.

2. Solvent

Common solvents used in degreasers include alcohols, ketones, and hydrocarbons, which may penetrate the pores of the stone and cause internal structural damage or discoloration.

3. Acidity and alkalinity

The acidity and alkalinity of degreasers vary from product to product. Acidic degreasers will corrode carbonate stones (such as marble), while strong alkaline degreasers may damage the surface structure of the stone, causing powdering or flaking.

3. Potential risks of cleaning stone with degreasing agent

1. Corrosion and discoloration

If the degreasing agent contains acidic or alkaline components, it may react chemically with the minerals in the stone, causing surface corrosion or discoloration. For example, marble will "burn" after contact with acidic substances, and the surface will become rough and dull.

2. Residue and contamination

The chemical components in the degreaser may remain in the pores of the stone, and long-term accumulation may cause the stone to discolor or produce odor.

3. Decreased glossiness

The glossiness of the stone surface is an important indicator of its aesthetics. The solvent or surfactant in the degreasing agent may damage the polishing layer on the stone surface, resulting in a decrease in glossiness.

4. Structural damage

If the degreasing agent penetrates into the interior of the stone, it may cause the stone structure to become loose, or even crack or peel.

4. Alternatives and Suggestions

In view of the potential risks of degreasers to stone, it is recommended to choose more suitable cleaning agents and methods when cleaning stone surfaces.

1. Special stone cleaner

There are many cleaners on the market that are designed specifically for stone. These products generally have a neutral pH and are able to effectively remove stains without damaging the stone surface.

2. Gentle cleaning method

For minor stains, use warm water and a soft cloth or sponge to wipe. Avoid using hard brushes or abrasive cleaning tools to avoid scratching the stone surface.

3. Regular protective treatment

Regular protective treatment of the stone surface (such as applying stone protective agent) can effectively prevent grease and other pollutants from penetrating into the stone.

4. Professional cleaning service

For stubborn stains or large area cleaning, it is recommended to seek professional stone cleaning services to ensure cleaning results and stone safety.

5. Conclusion

Although degreasing agent is an efficient cleaning agent, it is not suitable for direct use on stone surfaces. The natural characteristics and porous structure of stone make it very sensitive to chemical cleaning agents. The use of degreasing agents may cause corrosion, discoloration, loss of gloss and even structural damage. In order to protect the beauty and durability of the stone, it is recommended to choose a special stone cleaner or a gentle cleaning method and perform protective treatment regularly. For uncertain cleaning needs, consult professionals to ensure the long-term maintenance and cleaning effect of the stone.
