Usage Protocol<\/strong><\/h2>\n
    \n
  • Surface Preparation <\/strong>: Roughly clean the area to be treated to remove dust and superficial dirt. On heavily soiled surfaces, it is advisable to lightly brush before application to optimize the product’s effectiveness.<\/li>\n
  • Application of Oxalic Acid Solution <\/strong>: Pour the product directly onto the surface or apply it using a brush, sponge, or sprayer. For oxidized metals, immerse the rusted part or gently rub it with a cloth soaked in the product.<\/li>\n
  • Waiting Time <\/strong>: Let it act for 5 to 15 minutes, depending on the level of dirt and the type of material. Do not let the product dry on the surface to avoid any alteration, especially on natural stones and sensitive metals.<\/li>\n
  • Brushing and Rinsing <\/strong>: If necessary, scrub with a soft brush or sponge to remove tough residues, then rinse thoroughly with clear water to neutralize the action of oxalic acid.<\/li>\n
  • Drying and Finishing <\/strong>: Allow the surface to dry completely before applying protection if needed (varnish, finishing oil, or anti-rust treatment on metal). For optimal results, repeat the process if stains persist.<\/li>\n<\/ul>\n
