Gold plating is a thin layer of real gold bonded over a base metal. Treated reasonably it lasts years. Treated as though it were solid gold, it does not — and almost all of the damage comes from three ordinary habits rather than from anything dramatic.
Put it on last, take it off first
This is the whole of jewellery care compressed into one sentence. Perfume, hairspray, moisturiser, sunscreen and foundation are all mildly solvent, and every one of them attacks plating faster than skin does. Get dressed, do your hair, finish your face, and then put the jewellery on. Reverse it at night.
Perfume is harder on plating than a year of ordinary wear.
Take it off for water
Chlorine is the worst offender by a distance — a single afternoon in a pool can visibly dull a plated finish. Salt water is next. But ordinary showering is the one that quietly does the damage, because it happens every day: hot water, soap and friction, repeated. A piece that never goes in the shower will outlast an identical one that does, by years.
Sweat is worth mentioning honestly. It is mildly acidic, so the gym is not a good place for plated pieces. That is not a defect in the plating; solid gold would be fine and it also costs ten times as much.
Clean it with a dry cloth, and nothing else
Wipe pieces down with a soft, dry cloth after wearing to lift oils and sweat before they sit overnight. That is genuinely the entire cleaning routine.
What not to use: silver dip, jewellery polish, toothpaste, baking soda, or a polishing cloth impregnated with compound. All of these work by removing a microscopic layer of metal. On solid silver that is fine — you are taking off tarnish. On plating you are taking off the plating, and there is a finite amount of it. If a piece needs more than a dry cloth, warm water and the gentlest possible dab with a soft cloth, then dried immediately and completely.
Store it dry, dark and apart
Humidity accelerates tarnish on the base metal at any exposed edge, so a sealed pouch in a drawer beats an open dish in a bathroom. Keep pieces from rubbing against each other; plated surfaces scratch plated surfaces. The pouch your piece arrived in was chosen for this and is not packaging to throw away.
