What are the best methods to remove oil stains from polypropylene outdoor armchairs?

Oil stains on polypropylene outdoor armchairs can be stubborn, but with the right methods, they can be effectively removed. Here are the best techniques:

1. Dish Soap and Warm Water: Mix a few drops of dish soap with warm water. Scrub the stained area gently with a soft brush or cloth, then rinse thoroughly.

2. Baking Soda Paste: Create a paste using baking soda and water. Apply it to the stain, let it sit for 15-20 minutes, then scrub and rinse.

3. Rubbing Alcohol: Dampen a cloth with rubbing alcohol and blot the stain. Avoid scrubbing too hard to prevent damage to the polypropylene.

4. Vinegar Solution: Mix equal parts white vinegar and water. Spray or dab the solution onto the stain, let it sit for 10 minutes, then wipe clean.

5. Commercial Degreasers: Use a mild degreaser designed for outdoor furniture. Follow the product instructions carefully to avoid discoloration.

For tough stains, repeat the process or combine methods. Always test any cleaning solution on a small, hidden area first to ensure it doesn’t damage the material. Regular maintenance and prompt cleaning can prevent oil stains from setting in.
