Cleaning an osmium outdoor table requires special care to maintain its durability and luster. Osmium, known for its hardness and resistance to corrosion, still needs proper maintenance to stay in top condition. Here’s the best way to clean it:

1. Gentle Washing: Use mild soap and warm water with a soft cloth or sponge. Avoid abrasive cleaners that could scratch the surface.

2. Rinse Thoroughly: After washing, rinse with clean water to remove any soap residue.

3. Dry Immediately: Prevent water spots by drying the table with a microfiber cloth.

4. Polish Occasionally: Apply a metal polish suitable for osmium to restore shine and protect against oxidation.

5. Avoid Harsh Chemicals: Never use bleach or acidic cleaners, as they can damage the metal.

Regular cleaning will keep your osmium outdoor table looking pristine for years. Store it indoors during extreme weather if possible to prolong its lifespan.
