RF Plasma is a glow discharge typically generated through using oxygen and hydrogen as the input working gas. In the current study the radio frequency (RF) hydrogen plasma (H2) is used for removing some metallic stains (iron and copper) which affected the historical brick surfaces in Prince Yousef Kamal place. Untreated and treated surfaces were evaluated by OLS, EDX-SEM & FTIR. Investigation results show that both iron and copper aged samples had been cleaned, where the stains thicknesses' were removed perfectly through. Analytical results of the accumulated particles demonstrate that they are decreased after cleaning process. In addition, morphological investigations proved the clearness of positive effects in the reducing of the samples surfaces' darkening and thickness' accumulations in all cleaned samples.
