For the last two years I have thought that the chandelier in the solarium looked dull and yellowed due to age. It's probably the only light fixture that remains that was original to the house, so we have never even considered replacing it, but it wasn't all that pretty. The previous owner was very energy conscious so all of the bulbs in this house were/are compact florescent, so there are many bulbs that we still haven't changed since moving in. One of the lights in the chandelier finally went out the other night. I dragged a ladder over and looked inside the chandelier and the scene wasn't pretty. We took the bowl of the chandelier off and immersed it in a sink of hot ammonia water and rubbed gently and viola!
It's all sparkly and pretty again! This is definitely going to be added to the spring cleaning chores from now on.
