Dear Just:

Do NOT use bleach, as it may etch the crystal glass. Do NOT put in
dishwasher for the same reason. I would not use CLR either.

Most hand-cut crystal is made of slightly softer glass to facilitate
the cutting and harsh cleaners will make it cloudy.

Here's what one expert suggests for Waterford:

"To preserve its clarity, wash the bowl with mild liquid soap and warm
(not hot) water; do not wash in dishwasher as this may permanently
etch surface of crystal. Certain water may leave a lime or mineral
deposit on the crystal; if that happens, vinegar on a soft,
nonabrasive cloth will help remove the deposit. Rinse with warm water
and polish with a lint-free cloth. Do not store upside down on its rim
or stand on its rim on a draining board. Crystal can focus sunlight
into a concentrated beam that could potentially scorch rugs or
furniture, so do not store or display in direct sunlight. --Garland

If this doesn't work and you really want the vase, I'd take it to a
specialist in cut glass for buffing and cleaning. I know of one in
Flemington, NJ, but of course I don't know where you are located.
