Though some get nervous handling and cleaning expensive shades like Silhouettes, it is not difficult, nor does it need to be a "scary" experience.  With a proper understanding of this product and how to handle it during cleaning, it can be routinely and profitably cleaned.  On the other hand - it should be noted that with a careless pre-inspection, improper handling or sloppy cleaning protocols, disaster can easily strike - making it an expensive proposition indeed.
