PURPOSE:To completely remove sticking dust on the inner surface of a panel and efficiently obtain the titled smooth panel without correction, by cleaning the inner surface of the titled heat-treated panel with a brush using a cleaning solution, primarily washing the inner surface with water, subjecting the inner surface to acid cleaning treatment and carrying out the secondary washing with water. CONSTITUTION:The inner surface of the titled panel prepared by combining a panel without forming a fluorescent surface with a shadow mask and heat- treating the combined panel in a high temperature environment is physically brushed with a soft material, e.g. nylon brush, gauze, etc., for 10-15sec while supplying a cleaning solution to clean and remove sticking materials firmly sticking to the inner surface of the panel without damaging the panel. The inner surface thereof is primarily washed with water. The panel washed with water is then sprayed with a 10-18% hydrofluoric acid solution e.g. under 1-1.5kg/cm<2> pressure for about 15-30sec, to carry out acid cleaning treatment. The panel is secondarily washed with high-pressure pure water under, e.g. about 5kg/cm<2> pressure, coated with a resist, dried and sent to an exposing and printing process.
