ABSTRACT

  This Invention involve preparation at a matal – surface cleaning solution from Iraqi pomegranate peels ethanolic extract in two steps : 1st-stap : in valve ethanolic extraction at elagic acid it derivate and galic acid in a ratio (10:1) ethanol : pomegranate peels powder at (70℃) for two hours . 2nd – step : preparation at melal – surface cleaning solution by dilution at above ethanolic – extract with water in arato (10%) and wed or cleaning solution for removal at metal –oxide and aprecipitated layer from swtace at two allays :

  1. low carbon steel alloy
  2. brass allay

      Result was found to be a complete removal at metal – oxide and precipitated layer from surface at allays with in (4) hours upon immersion in a cleaning solution at room temperature.
