General cleaning tips:
- The glass can be wiped with a soft cloth, water and washing-up liquid.
- Avoid total immersion in water.
- Gently rubbing the solder with steel wool (only on silver-finished items) will bring back the shine should it dull over time.
- Car wax or multi-purpose furniture polish (e.g. Pledge or Mr Sheen) applied to the solder and buffed with a soft cloth will leave the seams shiny and with a protective coating.
