Jewelry in the Pool: What Chlorine Water Does to Your Necklaces

Jewelry in the swimming pool: what chlorinated water does to your chains. In short: Chlorinated water attacks silver, gold-plated brass, and soft solder joints. Stainless steel and titanium remain undamaged. If you swim regularly, you should take off silver chains beforehand and buy stainless steel jewelry for the pool, because no reaction occurs there. In practice, a 45 cm chain sits at the collarbone and therefore suits almost any neckline.

As of September 2026. By Phil, Corelune Jewellery, Düsseldorf.

In pool water, the free chlorine content in German swimming pools is usually between 0.3 and 0.6 mg per liter. Sounds like little. Over the course of a swimming season, it is enough to create a permanent gray layer on silver and make solder joints porous.

Chlorine reacts with silver to form silver chloride, a dull, grayish compound that, unlike normal tarnishing, can hardly be polished away. On gold-plated pieces based on brass, the water creeps through the pores of the coating, the underlying metal oxidizes, and the gold layer flakes off. Soft-soldered clasps lose their strength, which is why chains often break seemingly without reason weeks later.

Material in pool water

Sauna and hot tub

In the sauna, metal gets hot, and that also applies to stainless steel. At 90 degrees, a wide ring reaches temperatures that become uncomfortable on the skin. Fine chains are not critical, but you should take off wide bracelets. In the hot tub, the chlorine content is higher than in the swimming pool, so silver and brass react correspondingly faster.

The practical solution

Taking off jewelry before swimming sounds simple, but it regularly goes wrong in the changing room. Chains get caught in locker locks, rings slip into drains. That is exactly why stainless steel has established itself in the swimming pool: You leave it on and do not have to store anything. Briefly rinsing it under the shower after a swim so that no chlorine residues dry in the chain links is enough.

Corelune builds the catalog on exactly this use, because jewelry that you constantly have to take off eventually ends up in the drawer. How this works in the summer at the sea is explained in the article waterproof jewelry for the sea and pool. For the time after training, the article jewelry care after sports is suitable.

In the range, this corresponds to about: Gold necklace made of stainless steel, 238.0 g and Heart charm bracelet made of stainless steel. You can find more waterproof pieces in the category waterproof pieces.

What everyday life can withstand with chains and what it cannot

Anyone who knows when to briefly take off chains extends their lifespan by years. Most tension is created when putting on and taking off sweaters, more than during any athletic activity. Anyone who already rarely takes off the piece should at least make an exception before going to sleep.

How can you recognize quality in chains?

Between two visually identical pieces, the difference almost always lies in the workmanship, not in the material. Pay attention to evenly shaped components, because deviations indicate areas that will give way first under stress. The rest is a matter of taste, but these points are measurable and therefore a better standard.

Is the surcharge for chains worth it?

What a piece costs says less about its durability than most people assume. A twenty-five-euro piece that you wear two hundred times is cheaper than a ten-euro one in the drawer. If you are unsure, start with a basic piece and add to it later, instead of spending a lot at once.

What mistakes happen when buying chains?

The most common reason for a piece in the drawer is not quality, but a lack of suitability for everyday life. When giving it as a gift, the fact that it is decided according to your own taste instead of the recipient's taste is added. Anyone who remains unsure should opt for the simpler piece, because it is worn more often.

Frequently asked questions

Can chlorinated water damage stainless steel jewelry?

Not at the concentration of a swimming pool. Stainless steel forms a passive layer of chromium oxide that is stable against chlorine. Only in highly concentrated chlorine solutions, such as those used for pool cleaning, can pitting corrosion occur. Nothing happens during swimming itself.

How do I clean jewelry after the swimming pool?

Rinse under lukewarm tap water, pat dry with a soft cloth, especially between the links. No ultrasonic bath and no silver cleaner, both are too aggressive for gold-plated surfaces. Once a month with a drop of dish soap is enough for stubborn residues.

Why did my silver ring turn gray after the pool?

That is silver chloride, formed from the reaction between chlorine and the silver surface. Unlike normal tarnishing, this layer sits more firmly and can only be partially removed with a polishing cloth. In stubborn cases, only professional re-polishing by a goldsmith helps.

Which chain holds up during sports?

Short curb or link chains with a lobster clasp, because the tension is distributed over many links and there is little room for movement. Fine anchor chains and chains with heavy pendants do not belong in training, as that is where most breaks occur.
