SA2.5, also known as near-white blast cleaning is a method of preparing steel surfaces which, when viewed without magnification, shall be free of all visible oil, grease, dirt, dust, mill scale, rust and paint / coatings. Generally evenly dispersed very light shadows, streaks and discolourations caused by stains of rust, mill scale or previously applied paint / coatings may remain on no more than 5% of the surface
