Plinth stains on a metal outdoor table can be unsightly and 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 organic matter like leaves. This helps choose the right cleaning solution.

2. Prepare a Cleaning Solution:

- For rust stains: Use a mixture of white vinegar and baking soda. Apply the paste, let it sit for 15 minutes, then scrub with a soft brush.

- For organic stains: Mix warm water with mild dish soap. Scrub gently to avoid scratching the metal.

3. Scrub Gently: Use a non-abrasive sponge or brush to avoid damaging the metal surface. For tough stains, a nylon brush works well.

4. Rinse Thoroughly: Wash off the cleaning solution with clean water to prevent residue buildup.

5. Dry and Protect: Wipe the table dry with a microfiber cloth. Apply a metal protectant or wax to prevent future stains.

Regular maintenance, like wiping the table after rain or spills, will keep your metal outdoor table stain-free for years.
