stained glass care
To keep your stained glass looking it's best, you can occasionally give it a warm soapy bath with washing up liquid and wipe with a clean, dry microfiber cloth. The metal will naturally begin to oxidise over time. To brighten it back up, add a thin layer of carnauba car wax and gently buff it off in circular motions using a microfiber cloth. Avoid using standard abrasive glass cleaners as the chemicals will cause damage to the solder.
I would suggest hanging your piece from a hook, nail or existing fittings e.g window latch. Avoid using suction cups as they are not reliable. Always wash your hands thoroughly after handling as the solder contains a small amount of lead.
