Here's a usage guide for your Rectangular Concrete Table with Wooden Box Frame Legs:

1. Cleaning: Use a damp cloth with mild soap to wipe down the concrete surface regularly. Avoid using harsh chemicals or abrasive cleaners as they may damage the finish.

2. Protection: To prevent scratches or stains, it's advisable to use coasters or placemats under hot or wet items. Avoid placing sharp or heavy objects directly on the table surface.

3. Avoid Oil and Acid: Concrete is porous and can absorb liquids easily. Avoid spilling oil or acidic substances such as lemon juice, vinegar, or wine on the table surface. If a spill occurs, wipe it up immediately to prevent staining.

4. Sealing: Consider applying a concrete sealer to the table surface periodically to enhance its durability and resistance to stains. Follow the manufacturer's instructions for the best results.

5. Maintenance: Regularly inspect the table legs and wooden frame for any signs of wear or damage. If necessary, tighten loose screws or bolts and treat the wooden legs with furniture polish to maintain their luster.

By following these simple guidelines, you can ensure that your Rectangular Concrete Table with Wooden Box Frame Legs remains in excellent condition for years to come.
