Crystal is known for its sparkling, flawless appearance but it can quickly become dull when dirt or cloudy residue accumulates. The cloudiness can be caused by either excessive residue buildup or high mineral content in your water supply that settles when water splashes and dries onto the crystal. To keep the cloudy crystal looking its best, clean with mild ingredients that dissolve the residue without harming the crystal.
Fill a basin with enough water to submerge the vase.
Add 1 cup of white vinegar to the basin per gallon of water used.
Gently place the crystal in the basin and let it sit for an hour. The vinegar and water mixture softens and typically dissolves a large portion of the cloudy residue.
Remove the crystal from the basin carefully and scrub away any leftover residue with a nylon scrubbing pad.
Rinse the crystal and dry it with a clean, lint-free rag.
