When preparing to sell antiques, collectibles, vintage goods, or household items, the biggest beginner mistake is cleaning something that should have been left alone. Patina, surface oxidation, original finishes, historical residue, and age-related changes often prove authenticity—and removing them can dramatically lower resale value. At the same time, certain items benefit from gentle cleaning that improves presentation and buyer confidence.
