Sill stains on a metal outdoor table can be unsightly and stubborn, but with the right techniques, you can restore its shine. Here’s a step-by-step guide to effectively remove these stains:

1. Identify the Stain Type: Determine if the stain is from water, rust, or organic matter like leaves. This helps choose the right cleaning solution.

2. Prepare a Cleaning Solution:

- For general stains: Mix warm water with mild dish soap.

- For rust: Use white vinegar or a commercial rust remover.

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

3. Scrub Gently: Use a soft-bristle brush or sponge to avoid scratching the metal. Apply the solution and scrub in circular motions.

4. Rinse Thoroughly: Wash off the cleaning residue with a hose or damp cloth to prevent further staining.

5. Dry and Protect: Wipe the table dry and apply a protective wax or sealant to prevent future stains.

Regular maintenance, like covering the table when not in use, can also help keep it stain-free. With these simple steps, your metal outdoor table will look as good as new!
