How To Clean A Chandelier
Having a quick look around the internet here are some tips I found for cleaning chandeliers.
1.  Spray your chandelier with a mix of vinegar, water and rubbing alcohol. You will need 1/3 vinegar to 2/3 water or 50/50 if the crystals are particularly dirty. Then add from 3 tablespoons up to a quarter cup of rubbing alcohol. You may need to spray the chandelier 2 or 3 times before the drips run clear but it is still much faster than cleaning each and every crystal individually.
2.  When cleaning chandeliers with a spray, such as that explained above, make sure you protect the furniture and rugs that are underneath them. Use a plastic tarp with a cotton sheet on top of it. That way the plastic protects the floor and furniture from getting wet getting whilst the fabric stops the water from running anywhere by absorbing it.
3. To clean crystals individually and obviate the need for tarps mix 2/3 of a glass of white vinegar with 4 tablespoons of ammonia. Totally immerse each individual crystal piece in the liquid. hang them up to drip dry. You may want to place a cloth under the chandelier to catch the drips. Another suggestion is to suspend an big unverted golf umbrella under it until the drips have stopped.
