How do I get rid of the water marks that get left on my glass vases?

When the flowers have died (boohoo!) and I try to clean the vase, it leaves a nasty 'water line' mark. What will remove this without spending a fortune? Thanks....x

How do I get rid of the water marks that get left on my glass vases?
Leave badly stained cut glass over night in a mixture of water , detergent and a few drops of ammonia. To remove lime deposits, fill the glass vase with distilled water, leave for a week, then gently remove the crust with a toothbrush. Here´s a little bit more information for you. If glassware such as a decanter becomes stained inside, put a tablespoon of silver sand , obtainable from a garden shop, and a week solution of warm water and liquid detergent. Swill the contents round, but check frequently that the glass is not being scratched. Hope this helps a little

Reply:Leave to soak overnight in vinegar and water, any vinegar will do from malt, white and even white wine vinegar but for cheapness I'd use white.In the morning just empty out and wash in hot soapy water, no elbow grease required.
