I ALSO FOUND ANOTHER WAY TO CLEAN SILK AND ARTIFICIAL FLOWERS.  THAT USE BUBBLE BATH SOAP AND FABRIC SOFTNER.  WHAT YOU WOULD DO IS GET 2 SPRAY BOTTLES.   IN ONE BOTTLE YOU WOULD YOU SOME BUBBLE BATH AND WATER IN A BOTTLE.  IN THE OTHER ONE YOU PUT  FABRIC SOFTNER  AND WATER.  WHAT YOU WOULD DO IS USE THE BUBBLE BATH MIX FIRST;  THEN YOU WOULD WIPE IT OFF WITH A WASH RAG.  AFTER YOU HAVE DONE THIS THEN YOU WOULD USE THE FABRIC SOFTNER MIX AND SPRAY ON THE FLOWERS.  THIS IS USED TO GIVE THE FLOWERS A FRESH SMELL ON THEM.  THIS WILL ALSO GIVE YOUR ROOM A FRESH SMELL ALSO.
