Proper measures should be taken to ensure that your crystal glassware will last for the longest possible time. Rinse your glasses when you are done using them. Acidic liquids left in the glass too long can make the lead leak out of the crystal. Be extremely careful when cleaning your glassware. Avoid wiping off dust on the crystal because it may become scratched. Instead, eliminate dust by using a can of air. Do not place crystal glassware in the dishwasher. It is best to wash it by hand with a mild detergent. You may want to get faucet covers or line your sink with towels to avoid chipping the crystal. Allow the glassware to air dry as towels may scratch the crystal. It is best to store or display glassware in a dust free case. Avoid storing crystal glassware in direct sunlight and humidity. These elements can damage the glue. Accidentally breaking your glassware is always a possibility, but if you follow these tips, you’ll have less of a chance of that happening.
