Ventilated facade stains on outdoor tables can be stubborn, but with the right approach, you can restore your table's appearance. Here’s a step-by-step guide to effectively remove these stains:

1. Identify the Stain Type: Determine if the stain is from dirt, mold, or mineral deposits. This helps in choosing the right cleaning solution.

2. Prepare a Cleaning Solution: Mix warm water with mild dish soap or a specialized outdoor cleaner. For tougher stains, use a mixture of white vinegar and water (1:1 ratio).

3. Scrub Gently: Use a soft-bristle brush or sponge to scrub the stained area. Avoid harsh abrasives that could damage the table’s surface.

4. Rinse Thoroughly: After scrubbing, rinse the table with clean water to remove any residue.

5. Prevent Future Stains: Apply a protective sealant or wax to the table to make it easier to clean in the future.

Regular maintenance and prompt cleaning will keep your outdoor table looking its best. For persistent stains, consider consulting a professional cleaner.
