To clean an autolock buckle, especially one with a matte-finished steel, use a gentle method to preserve its finish and functionality:

• Mild Soap & Water: Mix a small amount of dish soap with warm water.
• Soft Cloth or Brush: Dip a soft cloth or an old toothbrush into the soapy water.
• Gently Scrub: Clean around the buckle, especially crevices. Avoid harsh chemicals or abrasives.
• Rinse & Dry: Rinse with clean water carefully and dry immediately to avoid moisture in the mechanism.
• For Tough Spots (Use Caution): Use a small amount of non-abrasive metal polish only if necessary, and test first on a hidden area.
