A hydrophobic and/or oleophobic coating system having a reversibly reduced hydrophobicity. A hydrophobic and/or oleophobic coating is applied to and is bonded or otherwise strongly adhered to a substrate, such as an optical lens. The coating has sufficient thickness to provide a weakly adhered, excess portion that is mechanically removable. The excess portion of the hydrophobic and/or oleophobic coating has a surface that is modified to reduce hydrophobicity, such as by ion bombardment. The hydrophobicity of the coating is restored by mechanical removal of the excess portion of the coating.
