Michael was waiting for me at the airport with roses when I came back from Minnesota. Beautiful roses that I had problems finding a vase that would fit them nice. I have 2 vases that are my favorite. And both very nice crystal vases. One is a Lennox and over the years the crystal has become cloudy. I have tried cleaning it with vinegar and baking soda and a tooth brush but it just doesn't do anything to improve it. So I told myself this time after these roses die, I would find a way to clean that vase. I rememered reading that people have used denture tablets on discolored vases so I decided to try it. I picked up a box of denture tablets at the dollar store. And let me tell you - it WORKED! Really well!
