These deposits can trap moisture and surface dirt, causing stains.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Cosmetics and perfumes: these can form a dull film that traps dust and affects the jewelry\u2019s shine.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">External iron contamination: prolonged contact with carbon steel particles (tools, steel wool, or metal dust) can leave iron residues on the jewelry. These particles can oxidize, creating \u201cbrown spots\u201d without the 316L itself rusting.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\">Corrosion in small areas: this can occur in tight areas of the jewelry where dirt, moisture, or salt accumulates for long periods. It is very rare in jewelry and can usually be prevented with regular cleaning.<\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Harsh chemicals: bleach, strong cleaning products, concentrated acids, or poorly balanced pool chemicals can cause stains or surface damage.<\/span><\/li>\n<\/ul>\n<h2><span style=\"font-weight: 400;\">How to treat persistent stains (without damaging the piece)<\/span><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Step 1 \u2013 wash: use warm water and mild soap, gently brush, rinse, and dry.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Step 2 \u2013 focus on specific spots: for stubborn areas, gently brush for 20\u201330 seconds without applying too much pressure.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Step 3 \u2013 check: if the stain was caused by an external deposit, it should disappear or become noticeably lighter.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Step 4 \u2013 targeted cleaning: if the stain persists, use a mild household stainless steel cleaner designed for stainless steel surfaces. Test it first on a less visible area, apply with a soft cloth, remove the product completely, and dry thoroughly. <\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">If the spots do not disappear, contact customer support with clear photos for further assessment. In rare cases of localized surface corrosion, the piece may benefit from professional polishing.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Gold pieces: can PVD rust?<\/span><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The PVD (Physical Vapor Deposition) coating provides a highly stable and durable gold finish. The base material remains corrosion-resistant 316L stainless steel.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Rust is uncommon on PVD-coated pieces. With very intensive use, the coating may gradually wear in areas exposed to greater friction, revealing the metallic color of the 316L underneath - without rust.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">To help preserve the color for longer: reduce continuous friction, <a href=\"https:\/\/mawad-atelier.com\/en\/como-limpar-aco-316l\/\">clean with water and mild soap<\/a>and avoid abrasive substances.<\/span><\/li>\n<\/ul>\n<h3><span style=\"font-weight: 400;\">Everyday wear: shower, sea, pool, and gym<\/span><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Showering and frequent washing: 316L handles water and mild soaps well; drying after each contact helps maintain its shine.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Beach: salt and sand can build up on the surface.

Try gentle cleaning and, if necessary, use a product specifically designed for stainless steel.<\/li>\n<li>Jewelry that looks dull: this may be caused by everyday wear, small marks, or a buildup of creams and cosmetics. A thorough cleaning will usually restore its shine.<\/li>\n<li>Gold color starting to fade: this means the PVD coating is gradually wearing with use.
