What is pH Neutral Soap?

pH neutral soap refers to a cleaning agent that has a pH level close to 7, which is considered neutral on the pH scale that ranges from 0 (highly acidic) to 14 (highly alkaline). This type of soap is designed to minimize the impact on the natural pH balance of the surfaces it cleans, whether they are human skin or various materials, including stones.

Marble and calcite-based-stones are sensitive to acidic environments, which can etch and damage their polished surfaces. Using a pH neutral soap ensures that the cleaning process is gentle, preserving the integrity and appearance of the stone. 

Does Regular Hand Soap Stain Marble & Calcite Surfaces?

Yes, regular hand soap can stain marble. Marble is a porous and sensitive material, particularly vulnerable to both chemical and physical damage. Here are several ways regular hand soap can cause issues for marble surfaces:

Chemical Reactions

Regular soaps often have a pH that is either acidic or basic. Marble, being composed primarily of calcium carbonate, reacts adversely to acids. Acidic soaps can cause what is known as etching on marble, which results in dull and discolored spots where the finish of the marble has been corroded.

Alkaline soaps might not etch marble as acids do, but they can still degrade the sealer used on marble, potentially leading to stains.

Dyes and Colors

Many hand soaps contain dyes to make them more visually appealing. These dyes can seep into the pores of the marble, leading to permanent discoloration if the marble is not properly sealed or if the sealant has worn down.

Soap Scum

Soap residues that linger on the marble surface can attract and bind with dirt, leading to a buildup of soap scum. This is not only unsightly but can also be difficult to remove, requiring more aggressive cleaning methods that could potentially harm the marble.

Oil and Fat Content

Some soaps include oils or fats to enhance their moisturizing properties. These substances can penetrate into marble and leave behind stains, especially if the marble is not adequately sealed.

For the reasons above, it is generally recommended to use pH-neutral, dye-free, and oil-free soaps for areas with marble surfaces to avoid potential staining and etching.

How do I know if my soap is pH neutral?

Here’s a guide on how to check the pH of your soap:

Materials Needed

• pH test strips or a digital pH meter
• Distilled water
• A container for mixing
• A spoon or stirrer

Procedure

• Create a soap solution. Shave or grate a small amount of the soap into the container.
• Add a small amount of distilled water (enough to fully dissolve the soap with stirring) to the container.
• Stir the mixture thoroughly until the soap is completely dissolved in the water, creating a soapy solution.
• Dip a pH test strip into the solution, ensuring it’s fully saturated, or use a digital pH meter to dip into the solution. Follow the specific instructions provided with your pH strips or meter for the most accurate results.
• Compare the color change on the pH strip to the chart provided with the strips, or read the value shown on the digital pH meter.

Interpreting Results

If your soap has a pH of 7, it is neutral. If it is higher than 7, it is alkaline, and if it is lower, it is acidic.

It's important to buy soap from reputable brands like MB Stone that adhere to manufacturing standards to ensure you're getting a product that is accurately labeled and has been tested for safety and effectiveness.
