Whether an heirloom that has been passed down or a new piece, precious crystal should be maintained for it to shine and sparkle to its full potential. If you notice water marks appearing on your crystal vases, then proper care hasn't been taken to ensure your vases are fully dry before storing or displaying. The gritty white look and texture of water marks can be removed without much difficulty.
Dip a portion of a clean cloth into a shallow bowl of distilled white vinegar. Rub the cloth over the water marks on the vase, using force as needed, until the water marks have been dissolved. Repeat process as needed.
Dampen a second cloth with warm water until the cloth is dripping. Place a drop of liquid dish detergent on the cloth. Rub the drop of detergent to work up suds.
Wash the crystal vase to remove the vinegar. Wash the inside and outside of the vase, using more water and soap as needed.
Rinse the vase with warm water to remove any soap residue. Dry the entire area, inside and out, with a third cloth to remove any water droplets and avoid future water marks. Repeat all four steps until all of your vases are clean.
If you have several crystal vases, fill a sink with water, 1 tbsp of dish detergent and 2 tbsp of vinegar and wash all of your pieces at one time.
Always wash crystal vases, bowls or stemware by hand to avoid cracks and breaks.
