A method of forming a self-cleaning coating on a substrate comprising the steps of: selecting a substrate; cleaning the substrate; roughening the substrate with an abrasive to create microscopic tortuous grooves, wherein the abrasive is moved down to contact the substrate and the substrate is moved back-and-forth along an X-axis with a first actuator to roughen the substrate, and the microscopic tortuous grooves created on the substrate range in depth from 1 μm to 1 mm; washing the substrate with de-ionized water; and coating the roughened surface with at least one hydrophobic chemical agent, wherein the at least one hydrophobic chemical agent is selected from the group consisting of trichloro(3,3,3-trifluoropropyl)silane, dichloro-methyl(3,3,3-trifluoropropyl)silane, chlorodimethyl(3,3,3-trifluoropropyl)silane, trichloro( 1H,1H,2H,2H -perfluorooctyl)silane, dichloro-methyl( 1H,1H,2H,2H- perfluorooctyl)silane, chlorodimethyl( 1H,1H,2H,2H -perfluorooctyl)silane, trichloro(3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl)silane, dichloro-methyl(3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl)silane, chlorodimethyl(3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl)silane, trichloro( 1H,1H,2H,2H -perfluorodecyl)silane, dichloromethyl( 1H,1H,2H,2H -perfluorodecyl)silane, chlorodimethyl( 1H,1H,2H,2H -perfluorodecyl)silane, trichloro( 1H,1H,2H,2H -perfluorododecyl)silane, dichloromethyl( 1H,1H,2H,2H -perfluorododecyl)silane, chloro-dimethyl( 1H,1H,2H,2H - perfluorododecyl)silane, chlorosilane, dichlorosilane, trichlorosilane, chlorotrimethylsilane, dichlorodimethylsilane, trichloromethylsilane, chlorophenylsilane, dichlorophenylsilane, trichlorophenylsilane, chloromethylphenylsilane, chlorodimethylphenylsilane, dichloromethylphenylsilane, chlorodimethylphenethylsilane, dichloromethylphenethylsilane, trichlorophenethylsilane, chlorodimethyldodecylsilane, dichloromethyldodecylsilane, trichlorododecylsilane, chlorodecyldimethylsilane, dichlorodecylmethylsilane, trichlorodecylsilane, chlorodimethyloctadecylsilane, dichloromethyloctadecylsilane, trichlorooctadecylsilane, chlorodimethyloctylsilane, dichloromethyloctylsilane, trichlorooctylsilane, chlorodimethylhexylsilane, dichloromethylhexylsilane, trichlorohexylsilane, chlorodimethylthexylsilane, dichloromethylthexylsilane, trichlorothexylsilane, allyldichloromethylsilane, allylchlorodimethylsilane, allyltrichlorosilane, (cyclohexylmethyl)chlorodimethylsilane, (cyclohexylmethyl)dichloromethylsilane and (cyclohexylmethyl)trichlorosilane;
