Transom stains on outdoor tables can be unsightly and challenging to remove, but with the right approach, you can restore your furniture’s appearance. Here’s a step-by-step guide to effectively eliminate these stubborn marks:

1. Identify the Stain Type: Determine if the stain is from rust, mold, or organic debris, as each requires a different cleaning method.

2. Prepare a Cleaning Solution:

- For rust stains: Mix equal parts white vinegar and water.

- For mold or mildew: Use a solution of 1 part bleach to 4 parts water.

- For general dirt: Warm soapy water with mild dish detergent works well.

3. Scrub Gently: Use a soft-bristle brush or sponge to avoid scratching the surface. Apply the solution and let it sit for 10-15 minutes before scrubbing.

4. Rinse Thoroughly: Hose down the table to remove all residue, ensuring no cleaning solution remains.

5. Prevent Future Stains: Apply a protective sealant or wax to the table surface to minimize future staining.

Regular maintenance and prompt stain treatment will keep your outdoor table looking pristine for years. For tough stains, repeat the process or consider commercial cleaners designed for outdoor furniture.
