Dry with a hairdryer (If a towel is used silicone may pick up fluff from the towel) Once completely dry a little unperfumed talcum powder can be dabbed over the surface then rub off excess. Do not use any other cleaning products as the chemicals can damage the silicone. Be careful not to spray any cosmetic products directly on to silicone or gold plated surfaces. An after care service is available if any of the silicone parts get damaged or you are unsure about cleaning. All silicone and silver parts are handmade. The silicone starts as a transluscent substance then colour pigments are added to create all the vibrant colours available and then hand-cast in moulds.
