To ensure the longevity and pristine condition of your "Versatile Two-Tiered Expandable Concrete Table," it's important to follow these usage instructions:

1. Avoid Oily Substances: Refrain from placing oily or greasy items directly onto the concrete surface. These substances can penetrate the concrete and may be challenging to remove, leading to stains.

2. Avoid Acidic Substances: Similarly, acidic substances such as lemon juice, vinegar, or acidic cleaners should be kept away from the concrete surface. These can cause etching or discoloration over time.

3. Use Coasters and Placemats: When placing glasses, cups, or hot items on the table, use coasters or placemats to provide a protective barrier between the concrete surface and the items.

4. Clean Spills Promptly: In the event of spills, promptly wipe them away using a soft cloth or paper towel. Avoid letting spills sit for an extended period, as they may seep into the concrete and become more difficult to clean.

5. Regular Cleaning: For routine cleaning, use a mild soap or detergent mixed with water and a soft cloth to gently wipe down the surface. Avoid abrasive cleaners or scrubbing pads, as they may scratch or damage the concrete.

By following these guidelines, you can ensure that your "Versatile Two-Tiered Expandable Concrete Table" remains in excellent condition, maintaining its beauty and functionality for years to come.
