Clean glass with a soft cloth or paper towel dampened with glass cleaner (do not spray cleaner directly onto vase or beadwork). 

If beadwork needs cleaning, gently hand wash in lukewarm water with mild soap, rinse & pat dry with a soft towel.  Do not let beadwork soak in water, as that may loosen glue on knots.  Harsh cleaners or detergents may harm the finish on the beads or weaken the thread.  Do not let the beadwork hang when wet – lay it as flat as possible (turn the vase upside-down on a towel) until dry. This will help keep the thread from stretching.

If vase is used for flowers and hard water stains develop, fill vase with warm water and add cut-up grapefruit rind & let stand. Another method is to add a denture-cleaning tablet instead.
