To clean chandeliers, there is an easy way and a not so easy way. The not so easy way may be necessary if there is a heavy accumulation of grime, or if the chandelier is located near a kitchen where grease might soil the surface. Both methods require you safely be able to access the fixture. Many newer chandeliers, and commercial units are installed on a winch that can raise or lower the unit with the turn of a switch.
Tools & Technique:
The easy way requires the power to the unit to be off. It is a good idea to turn off the breaker to be certain.
Using small plastic bags, cover each light fixture and secure with elastic bands.
Mix a spray of warm water and rubbing alcohol in a 10-1 ratio.
Place a heavy towel under the chandelier, and spray the mixture onto every crystal.
Allow the fixture to drip dry, there shouldn’t be any streaks and the crystals should sparkle like new.
Allow the whole unit to dry for 24 hours before restoring power.
The hard way is similar, only harder. Much harder.
Remove 10 or 12 crystals at a time, any more than this and you run the real risk of having a much different looking chandelier by the time you are finished.
Dip each crystal individually into a bucket of the same mixture. For greasy films, add a few drops of dish washing soap.
Rinse each crystal individually. Then lay out each on a terry towel.
Polish each crystal and return it to its place on the chandelier.
These crystals will break, and chip each other so dip and rinse only one at a time, and try using a clear bucket so you can see what you are doing.
This is very labor intensive, and once you start you are committed to finish because the dirty crystals look like hazy chunks of plastic next to the clean and polished ones.
