Scrape off any debris or caked-on food from the table. Hold a paint scraper or any other metal scraper at a 45-degree angle to the table. Scrape away from you, releasing food and grime from the table.
Attach 80-grit sandpaper to an orbital sander. Move the sander across the table to remove stains and scratches. Start with a higher grit paper if the table is not heavily scratched or stained.
Switch the sander to a finer grit paper. Sand the surface again. Continue switching the paper and sanding the surface of the table until you have a soft, smooth surface. Run your bare hand over the table top. The surface should be soft and free of bumps or dings.
Combine one part paraffin with four parts mineral oil. Work the solution into any cracks in the block. The solution will fill the cracks. Allow the solution to set in the crack on the table. Scrape off excess wax with the metal scraper.
Wipe the table with vinegar to remove all grease and grime from the surface. Place a small amount of vinegar on a clean rag. Rub the table’s surface with the rag to clean.
Dip a soft cloth or t-shirt in mineral oil. Rub a coat of mineral oil over the butcher block table. Wipe off any excess oil.
