Purosol Optical was originally developed for NASA and the US military for use on high-end multi-coated optics. Combining the power of organic plant extracts and state-of-the-art green chemistry, it is the world’s most advanced cleaning solution. Taking its cleaning power from nature itself, Purosol Optical is non-toxic, hypoallergenic, nonflammable, sterile and completely biodegradable. It is CFC-free, VOC-free and exceeds EPA and OSHA health and safety standards, as well as exceeding standards set for the EU, Australia, Canada, Japan, and other countries worldwide.
