The Liner Wand contains Apocrine , a specially formulated and patented cleaning and decontaminating solution that is designed to leave a barrier coating behind on your liner surface. The effectiveness lies in the patented process of combining isopropyl alcohol, a known disinfecting agent with silver titanium, equally known for its long-lasting bacterial fighting properties. These two components are brought together and activated as you break up the ampoules contained inside the Wand giving you a powerful cleaning and decontaminating agent that acts fast to give you protection from bacteria by-products, which leads to odor and the increased chance of infection. Most users also report a tighter fit and increased comfort!
