How to Clean Gua Sha Tools – The Differences Between Different Gua Sha Materials
In both professional wellness settings and daily personal skincare routines, Gua Sha tools are used in direct contact with the skin. From a manufacturer and wholesale perspective, proper cleaning is not only about hygiene, but also about material protection, product longevity, and regulatory compliance. At Deyi Gems, with years of experience in Gua Sha production and global wholesale supply, we have observed that incorrect cleaning methods are one of the most common reasons for premature product damage and customer complaints. Different Gua Sha materials react very differently to water, oils, detergents, alcohol, and temperature changes. A jade Gua Sha board, for example, cannot be cleaned in the same way as stainless steel or resin. Understanding these differences is essential for wholesalers, brands, spas, and end users alike. This article focuses on how to use gua sha tools, explaining correct methods for different materials while providing authoritative data and standards to support best practices. Understanding Gua Sha Tool Cleaning as a Core Usage Practice Why Cleaning Is a Functional Part of Gua Sha Usage Gua Sha is not a disposable skincare practice. Each tool is designed for repeated use over months or even years. During use, the tool comes into contact with facial oils, massage creams, sweat, and exfoliated skin cells. If residue accumulates, it can reduce glide performance, affect skin comfort, and increase the risk of bacterial growth. According to the U.S. Centers for Disease Control and Prevention (CDC), non-porous personal care tools that contact skin should be cleaned after each use to reduce microbial contamination. While Gua Sha tools are not medical devices, this hygiene principle still applies, especially in spa or professional environments.

Clear cleaning instructions reduce product returns, extend service life, and help brands comply with consumer safety expectations. The U.S. Food and Drug Administration (FDA) emphasizes truthful usage and care instructions for consumer products to prevent misleading claims. Source: https://www.fda.gov/consumers Material Differences: Why One Cleaning Method Does Not Fit All Natural Stone vs. Man-Made Materials Gua Sha tools can be broadly divided into natural stone materials and engineered materials. Natural stones such as jade, rose quartz, and obsidian are formed with microscopic pores and natural fissures. Man-made materials such as stainless steel, resin, and glass are more uniform and generally less porous. This structural difference directly affects water absorption, resistance to chemicals, and tolerance to temperature. Ignoring these material properties during cleaning can lead to cracking, discoloration, or surface dulling. Porosity and Absorption Explained According to geological material studies published by the U.S. Geological Survey (USGS), many natural stones exhibit micro-porosity even when polished. These pores are invisible to the naked eye but can absorb oils and moisture over time. Source: https://www.usgs.gov How to Clean Jade Gua Sha Tools Safely Characteristics of Jade Relevant to Cleaning Jade, including nephrite and jadeite, is valued for its density and smoothness. However, despite its hardness, jade can still absorb oils through micro-pores. Excessive soaking or harsh detergents may weaken the stone over time. In manufacturing, jade Gua Sha tools are usually polished to a mirror finish, but polishing does not eliminate internal porosity. This makes gentle cleaning essential. Recommended Cleaning Method for Jade Gua Sha For daily clean gua sha tools, lukewarm water combined with a mild, fragrance-free soap is sufficient. The tool should be rinsed quickly and wiped dry with a soft cotton cloth. Prolonged soaking is not recommended, as water penetration can cause internal stress. According to material care guidance from the Gemological Institute of America (GIA), jade should never be exposed to harsh chemicals or ultrasonic cleaners. Source: https://www.gia.edu How to Clean Rose Quartz Gua Sha Tools Properly Material Properties of Rose Quartz Rose quartz is a crystalline form of silicon dioxide with a Mohs hardness of approximately 7. While relatively hard, it is more brittle than jade and prone to internal fractures when exposed to sudden temperature changes. From a wholesale perspective, rose quartz tools often receive complaints related to cracking caused by improper cleaning or storage. Cleaning Best Practices for Rose Quartz Rose quartz Gua Sha tools should be cleaned using warm water and a mild cleanser, similar to jade. Alcohol-based disinfectants should be avoided for frequent use, as they may dull the surface polish over time. The National Institutes of Health (NIH) notes that overuse of alcohol on consumer-grade tools can degrade surface finishes, even when microbial reduction is achieved.

While it appears solid, its internal structure is glass-like and can be sensitive to impact and temperature shock. This makes cleaning practices especially important. Unlike jade or quartz, obsidian is less porous but more brittle, meaning physical handling matters as much as chemical exposure. Proper Cleaning Approach for Obsidian A soft cloth dampened with water is often sufficient for routine cleaning. Mild soap can be used occasionally, but the tool should never be soaked or exposed to boiling water. Abrasive sponges must be avoided, as they can cause micro-scratches. Stainless Steel Gua Sha Tools: Industrial Hygiene Advantages Why Stainless Steel Gua Sha Is Easier to Clean Stainless steel Gua Sha tools are increasingly popular in professional settings due to their non-porous surface and high resistance to corrosion. Medical-grade stainless steel, such as 304 or 316L, does not absorb oils or bacteria. According to ISO 7153-1 standards, stainless steel used in surgical instruments demonstrates high resistance to repeated cleaning and disinfection cycles. Source: https://www.iso.org Cleaning and Disinfection for Stainless Steel Stainless steel Gua Sha tools can be cleaned with warm water, soap, and even alcohol-based disinfectants without damage. For spa environments, they can be sanitized between clients using 70% isopropyl alcohol, which the CDC identifies as effective against most surface pathogens. This durability significantly reduces maintenance concerns for wholesalers and professional buyers. Resin and Acrylic Gua Sha Tools:
