How To Remove Old Alligatored Shellac From Antique Clock Case

Antique clock cases often have a unique charm, but old, alligatored shellac can dull their beauty. Removing this aged, cracked finish may sound challenging, but with the right steps, you can restore your clock case to its former glory. Let’s get started!

What Is Alligatored Shellac?

Alligatored shellac occurs when the finish deteriorates over time, forming a cracked, uneven surface that resembles alligator skin. This is common in antique furniture and clocks exposed to fluctuating humidity and temperature.

Tools and Materials You’ll Need

• Denatured alcohol
• Fine steel wool (000 or 0000 grade)
• Clean, lint-free cloths
• Soft bristle brush
• Drop cloth or protective covering
• Rubber gloves
• Mask (optional, for ventilation)

Step-by-Step Guide to Remove Alligatored Shellac

1. Prepare Your Workspace:
   
   • Choose a well-ventilated area to work in.
   • Lay a drop cloth to protect your work surface.
2. Test a Small Area:
   
   • Dampen a small cloth with denatured alcohol.
   • Rub a small, inconspicuous area of the shellac to test its solubility.
   • If the shellac dissolves, proceed to the next steps.
3. Apply Denatured Alcohol:
   
   • Dampen the steel wool with denatured alcohol.
   • Gently rub the surface of the clock case in circular motions.
   • Avoid pressing too hard to prevent damaging the wood underneath.
4. Wipe Off Residue:
   
   • Use a clean, lint-free cloth to wipe away the dissolved shellac and residue.
   • Repeat as necessary until the entire surface is clean.
5. Detail Cleaning:
   
   • Use a soft bristle brush dipped in alcohol to clean intricate areas, carvings, or corners.
   • Wipe with a cloth to remove any remaining shellac.
6. Finish the Surface:
   
   • Allow the wood to dry completely before refinishing.
   • Reapply a fresh shellac coat or a modern finish for protection and shine.
