Girder 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 rust, dirt, or grease, as this affects the cleaning method.

2. Prepare a Cleaning Solution:

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

- For grease or dirt: Use a mild dish soap with warm water.

- For tough stains: Baking soda paste (baking soda + water) works well.

3. Scrub Gently: Apply the solution to the stained area and scrub with a soft brush or sponge. Avoid harsh abrasives to prevent surface damage.

4. Rinse Thoroughly: Use clean water to rinse off the solution, ensuring no residue remains.

5. Dry and Protect: Wipe the table dry and consider applying a protective sealant to prevent future stains.

For persistent stains, repeat the process or use a commercial cleaner designed for outdoor furniture. Regular maintenance will keep your table looking pristine.
