Light Scratches

• 1). Dampen the wadded end of a clean cloth with mineral oil.
  
  
• 2). Rub the scuffed area, using medium pressure to buff out the scratches.
  
  
• 3). Wash the area with warm, soapy water. Rinse the stone, and then allow it to dry. Repeat the process if any signs of the scratches remain.
  
  

Medium Scratches

• 1). Sand the scratched area with silicon carbide 300-grit sandpaper, applying firm pressure to shear the stone surface until the scratches disappear. For large repair areas, use a power sander.
  
  
• 2). Massage the sanded area with mineral oil, using a clean cloth.
  
  
• 3). Wash the area with warm, soapy water. After the limestone dries, inspect the area. Repeat the process if there is still evidence of the scratches.
  
  

Deep Scratches

• 1). Abrade deep scratches with 100-grit silicon carbide sandpaper, using a power sander. Once the scratches become nearly invisible, finish sanding with 300-grit sandpaper.
  
  
• 2). Rub the sanded limestone surface with mineral oil.
  
  
• 3). Clean the stone with soap and water, and leave it to dry. If any of the scratches still show, sand the area again with 300-grit sandpaper, then re-treat with mineral oil and wash the area thoroughly.
