What are the best cleaning methods for stained polyethylene outdoor flower pots?

Polyethylene outdoor flower pots are durable and lightweight, but over time, they can accumulate stains from dirt, algae, and mineral deposits. To restore their appearance, follow these effective cleaning methods:

1. Soap and Water Scrub: Mix mild dish soap with warm water and use a soft brush or sponge to scrub the stains. Rinse thoroughly.

2. Vinegar Solution: Combine equal parts white vinegar and water to tackle mineral deposits and algae. Let it sit for 10-15 minutes before scrubbing.

3. Baking Soda Paste: For stubborn stains, make a paste with baking soda and water, apply it to the pot, and scrub gently.

4. Bleach Dilution: For deep stains or mold, use a diluted bleach solution (1 part bleach to 9 parts water), rinse well afterward.

5. Pressure Washing: For large or heavily stained pots, a low-pressure washer can quickly remove grime without damaging the material.

Regular cleaning prevents long-term staining and keeps your pots looking new. Always rinse thoroughly after using any cleaning solution to protect your plants.
