Outdoor trash cans often develop a white haze over time due to sun exposure, oxidation, or residue buildup. To prevent this issue, follow these practical tips:

1. Regular Cleaning: Wash your trash cans monthly with warm soapy water and a soft brush to remove grime and prevent residue buildup.

2. UV Protection: Apply a UV-resistant spray or keep trash cans in shaded areas to minimize sun damage, which causes discoloration.

3. Avoid Harsh Chemicals: Use mild detergents instead of bleach or strong cleaners, as they can degrade plastic and cause whitening.

4. Vinegar Solution: For existing haze, scrub with a mix of vinegar and water to break down mineral deposits without damaging the surface.

5. Protective Coatings: Consider using a silicone-based polish to create a protective barrier against environmental factors.

By maintaining your trash cans properly, you can extend their lifespan and keep them looking clean and haze-free.
