How do I clean a grapevine wreath with silk flowers?

I have a large grapevine wreath just loaded with silk vines, foliage, artificial berries, and silk flowers of various kinds and sizes. Some of the flowers, such as the hydrangeas, are intricately detailed with dozens of tiny petals.



The wreath has been in place for several years with nothing more than an occasional flick of a feather duster to re-distribute the dust. It's very dusty. Any ideas on how to clean it without messing up all the greenery and flowers?



Thanks in advance.

You can buy a can of air blower/ keyboard cleaner at Walmart or a computer store.
Reply:it's all washable- fill a sink with mild sudsy water submerge the wreath . let the water out and slowly fill with cool let it sit a few minutes then let the water out. let it dry in the sink. I shouldn't disturb the arrangement. whatever floats away was rotten anyhow and probably growing mold etc.
Reply:I would suggest using water mixed with a little dish soap and either use an old spray bottle or just a soft cloth and wipe it down. There are also silk flower cleaners available online or at any local craft store if you want to go with something a little more professional -- but warm water and a bit of soap should do the trick just fine.
