Efflorescence is the appearance of white crystalline deposits of calcium carbonate or calcium sulfate on the surface, joints, or cracks of stone materials. It may present itself in a powdery or solid form.

Before discussing methods of treating and preventing efflorescence, it's essential to understand its causes. Unlike soap scum, efflorescence occurs due to the leaching of calcium hydroxide from the cement paste used in bonding stone materials. This leached calcium hydroxide then permeates the stone surface or emerges from joints and cracks. Upon reacting with carbon dioxide in the air or rainwater, it forms calcium sulfate or calcium carbonate. As the moisture evaporates, white crystalline deposits appear. (Editor's note: Too many chemical terms, don't worry about memorizing them! In simple terms, it's similar to the concept of stalactites.)

Efflorescence is related to moisture and humidity, which can include rainwater, air humidity, water leaks from pipelines beneath the stone, prolonged use of wet mops, and water usage in shower areas or bathtubs. Consequently, efflorescence is more likely to occur in areas with a water source, such as outdoor stairs or walls, joints in exterior walls, bathroom floors or walls, indoor floors in humid or mountainous regions, and stone floors frequently cleaned with wet mops.


When you notice efflorescence, it's crucial to address it promptly, as it will continue to spread and grow, increasing the difficulty of future treatment.

So, how do you deal with stone that has already developed efflorescence?

Please use XShine "Stone Efflorescence Remover." With its unique dissolving formula, the efflorescence remover can quickly melt and dissolve white crystalline deposits such as calcium carbonate and calcium sulfate. If the efflorescence is thick, you can apply the remover multiple times or use a super-thin blade or a brass wire brush for assistance. For detailed usage instructions, please refer to: https://bit.ly/398G0VN.


After completing the efflorescence removal, it's important to focus on prevention. As long as environmental humidity or water sources are present, efflorescence may reoccur in the future. For effective prevention of efflorescence, please use XShine "Stone Efflorescence Prevention Agent" and ensure the stone remains dry. Indoors, ventilate to eliminate moisture, avoid using excessively wet mops for cleaning, and wipe the bathroom dry after use. If there is water seepage or pipeline leaks underground, please cut off the source of underground water seepage.
