Abstract
Devices and compositions are provided for cleaning optical surfaces with carbon black. Carbon black may be impregnated on a soft pad, such as chamois leather, to provide a lens cleaning device. The soft pad may be supported on a handle. The soft pad may be mounted on the handle by a resilient member that is capable of adapting with the soft pad to conform the cleaning surface to concave or convex optical surfaces. A retractable brush may be mounted at the opposite end of the handle from the soft pad.
