Of course you want your Dutch Jewellery to stay as beautiful as possible. Some advice to have your ‘Zeeuwse knopen’ remain nice and shiny:
When you’re going to exercise, clean or do heavy work, or go to sleep or shower, please take off your jewellery.
If you don’t wear the jewellery, please store the item or items with care. Wrap the jewellery in soft cloth or put the items in a box so they don’t touch other jewellery. That may cause unnecessary scratches and damage.
Silver and bronze jewellery remains beautiful by brushing occasionally gently with a soft toothbrush.
Do not use chemicals or a rough fabrics to clean your Dutch jewellery.
Avoid sulfur-containing liquids and chlorine. It makes silver turn black.
