Enzymes are naturally occurring substances whose sole purpose is to break down organic matter. Organic plant enzymes make up the powerful cleaning agent in Hoodman’s Lens Cleanse natural lens cleaning kits. The delicate optical coatings of your lenses and filters are never compromised because Lens Cleanse enzymes do not hurt optical coatings. Even the cleaning kit towelletes we use are special. Lens Cleanse towelletes are made up of super soft natural wood fibers that will not scratch lenses or filters. Hoodman Lens Cleanse natural lens cleaning kits are good for your lenses, filters and the environment too!
