Water, lotions and cleaning products are gold-plated jewelery’s ennemies so avoid any contact between your gold vermeil Magal pieces and those substances. It is also preferable to take the jewelery off when working out, as sweat can also affect their shine. Once in a while, you can clean your pieces with a soft and dry cotton or microfiber cloth. Do not use jewelry cleaner on gold plated jewelry, it is too harsh for them.
