How do you pre clean lead crystal?

To pre-clean lead crystal, start by rinsing it with warm water to remove any dust or debris. Use a gentle dish soap and a soft sponge or cloth to carefully wash the surface, avoiding abrasive materials that could scratch the glass. Rinse thoroughly with clean water to remove any soap residue, and dry with a lint-free cloth to prevent water spots. Always handle lead crystal with care, as it can be delicate and prone to chipping.
