Stainless steel is a common term for an alloy which exhibits exceptional strength, resistance to rust, and is visually appealing due to its shine. This material is utilized in many items ranging from jewelry, kitchen tools to various appliances. However, many ask, "Does Stainless Steel Turn Skin Green?" The short answer is yes, but only at times. This article will delve deeper and explore why stainless steel causes green discoloration on skin, prevention methods, and how to treat it if it occurs.
What Causes Stainless Steel to Turn Skin Green?
Usually, when a chemical reaction occurs, this is why stainless steel may turn skin green. This typically takes place when certain metals within the alloy react and combine with the moisture or perspiration present on your skin. It would now be better to take a closer look at these reactions.
The Metals In Stainless Steel
Stainless steel is defined as an alloy which is made out of various metals with iron being the base metal. To enhance properties such as durability, strength, and resistance to rust, other metals such as Chromium, Nickel, Molybdenum, and Carbon are added. The metals present in stainless steel are:
Chromium: (at least 10.5 %) — This prevents rust.
Nickel: Provides corrosion resistance and shine.
Molybdenum: Increases strength while providing acid resistance.
Carbon: Imparts hardness to the stainless steel.
On the other hand, the presence of copper in stainless steel, even in low-quality variants, can pose serious issues.
Copper and Oxidation
Copper is the primary reason behind the green stains that can potentially form on your skin as a result of wearing stainless steel jewelry. When worn, copper reacts with sweat, moisture, and oxygen, resulting in a green-colored substance known as patina. This is known as green patina and it can easily rub itself onto your skin, resulting in green color stains.
Over oxidation is common regarding inexpensive stainless steel products, as they are made with a higher amount of copper and other oxidizing metals. Diamond-embellishment plated alloys made with lower-quality stainless steel have a thin layer of stainless steel, so copper is exposed and results in quick oxidation.
Body Chemistry and External Factors
Each individual is different, therefore stainless steel affects each person differently. A small portion of the population has more acidic skin and greater levels of moisture or sweat, leading to quicker oxidation. For example, wearing stainless-steel jewelry during a workout or in hot weather will cause sweat to oxidize the metal and leave the wearer with green staining.
To summarize, the presence of a body’s copper combined with moisture and body chemistry can, in certain circumstances, result in green discoloration on the skin.
Does All Stainless Steel Result in Green Skin Discoloration?
The stainless steel that green skin discoloration is associated with does not apply to all stainless steel. The type of stainless steel and its quality are very important factors when determining if skin will be affected. Let us identify some types of stainless steel that are less likely to result in discoloration.
High-Quality Stainless Steel Grades
Some stainless steel grades are known to be skin-friendly and are not likely to cause discoloration. These are the types that are less prone to having copper and other alloys that result in oxidation:
304 Stainless Steel: It is a grade of stainless steel used in kitchenware and jewelry. It has 8% nickel and 18% chromium. This grade is also known for resistance to rust and is mostly used in high-quality products.
316L Stainless Steel: 316L is well known for its ability to resist corrosion. Its foremost application is in medical instruments and in jewelry of the upper class. It has molybdenum added to it which helps further increase strength and resistance to rust. It is hypoallergenic and is less likely to cause reactions.
Such high-quality grades are considered safe for many people and are not likely to result in green discoloration of skin.
Mixed Alloys and Lower-Grade Stainless Steel
Alloys that contain higher copper content, or those that are classed as lower quality, are more likely to cause green discolorations. Some jewelry or items manufactured in low-grade stainless steel are known to have copper that undergoes oxidation due to sweat and moisture.
If you are particularly concerned about green stains, you should only purchase high-quality stainless steel.
Skin Green Mark Prevention for Stainless Steel Items
In case you do not want to deal with the fuss of skin green marks, there are a few measures you can take. Let’s examine some simple ways to safeguard against skin green discoloration.
Buy High-Quality Stainless Steel
The most effective solution to stop stainless steel from discoloring your skin is to use high-quality products. Select stainless jewelry or products from brands that offer surgical grade or 316L stainless steel items. These steels are hypoallergenic and have reduced chances of skin irritation or reactions.
Reduce The Level of Moisture
Moisture is one of the leading causes for oxidation. If you desire to prevent green stains, it is best to avoid stainless steel jewelry in these scenarios:
During exercise routines: Sweating increases moisture and acidity on the skin, which further drives oxidation.
While swimming: Chlorine as well as saltwater can promote oxidation, which leads to a green stain.
Long showers: Providing prolonged exposure to water, which can adversely affect the metal, especially if the stainless steel is of poor quality.
If you maintain your stainless steel pieces dry, it will limit its chances of reacting with your skin.
Avoid Exposing Your Skin to Moisture
Shower and gradually dry your body. Before applying jewelry, you can apply a light coating of either talc powder or an antiperspirant. This powder will aid in reducing sweat and moisture while assisting in preventing oxidation from occurring.
Establish a Protective Covering
In case you put on jewelry that has a high probability of tarnishing the skin to green, then polish the edge of the jewelry with a fine layer of clear polish. This will assist in keeping the skin and the jewelry away from each other, restricting further oxidation.
What To Do If You Get a Green Stain from Stainless Steel Jewelry
Even while taking precautions, it is possible to still be stained green from your stainless steel jewelry. However, these stains should not affect your health and can be washed away gently. Here’s how you can eliminate the green marks:
Rinse Your Skin: To remove the discoloration, scrub the area with warm water and a mild soap. Avoid excessive scrubbing, as that may irritate your skin further. Continue rinsing the affected area until the stain disappears.
Hydrate Your Skin: After the skin cleanup, rub a gentle lotion without fragrance to help moisturize and soften the skin. This will also take away irritation caused by the stain.
Maintain Your Jewelry: Make sure to regularly clean your stainless steel jewelry. If not, you will have future discoloration. Replace any dirt or oils that may have accumulated on the pieces with a soft cloth and mild soap.
Microsoft Steel to Maintain Proper Usage
Regular maintenance of stainless steel appliances can enhance their look as well as save your skin from discoloration. To further assist you here are some useful tips:
Wipe Thoroughly After Cleaning: Every time you clean stainless steel appliances, make use of a microfiber cloth cleaning as it guarantees no leftover wet spots and rust. Do not leave the appliance to air dry.
Use Dish Soap at Least Once a Week: A mixture of warm water and mild dish soap is the most simple yet effective method of cleaning steel appliances. Dip the appliance in the warm soapy water for a few minutes, then massage it with a soft-bristle toothbrush, rinse the soap with lukewarm water, and wipe dry immediately.
Clean Steel with Natural Ingredients Only: Harsh ingredients like bleach or ammonia should be left unchecked as using them will permanently ruin the stainless steel surface. Stubborn stains can be easily fixed with natural alternatives like soda and vinegar.
Decrease Salt Usage: With continuous use, salt can weaken the stainless steel. If saltwater is used, the steel must be rinsed thoroughly and dried in order to stay intact.
