Identify the item and finish
Check maker labels, purchase records, care documents and any prior restoration. Note whether the item is decorative, functional, plated, lacquered, patinated or valuable. Appearance alone does not establish the metal or finish.
Check the maker or conservator’s instructions
For a modern item, ask the maker for current care guidance. For antiques, heritage objects or unknown coatings, consult a qualified metals conservator before applying a cleaner or polishing tool. Do not scrape, sand or test an acid on a hidden area without expert advice.
Avoid cross-surface recipes
Do not assume lemon, vinegar, baking soda, toothpaste, salt or a commercial polish suits the item. Read the exact product label and confirm that the object’s finish maker permits its use. Never mix cleaning products.
Set a professional cleaning scope
Tell any provider the item’s maker, material if known, dimensions, value, condition and previous products. Ask whether the provider handles the exact finish, what product is proposed, what is excluded and whether the work may alter patina or coating. No restoration or shine result is guaranteed.
Keep valuable or historic objects separate
A routine house clean is not metal conservation, appraisal or restoration. Remove or protect valuable objects only as the owner and conservator direct; do not authorize polishing or stripping as an incidental cleaning task.
