“…General conclusions suggest that laser cleaning better preserves surface topography [27,29]; however, laser cleaning introduces the risks of micromelting and/ or redeposition of ablated material [10,20,24,26,27]. Many studies conclude that optimized iron corrosion removal combines laser cleaning and traditional mechanical techniques, citing a limit to the effectiveness of lasers in removing very thick corrosion layers or particular corrosion species [18,21,23,26,28].…”
