🧼 Why Do White Plastic Chairs Turn Yellow or Dirty?

Before we clean, let’s understand the culprit:

• UV Exposure: Sunlight causes plastic to oxidize and yellow.

• Dirt & Grime: Outdoor use means they collect dust, pollen, mold, and stains.

• Pollution: Airborne pollutants can settle on the surface.

• Age: Over time, the plastic naturally fades and loses brightness.

Luckily, most of this is surface-level and can be reversed with a little effort.

🚫 Avoid These Mistakes

• Don’t use chlorine bleach – It can degrade plastic over time and cause it to become brittle.

• Avoid abrasive wire brushes – They can scratch the surface, making it more prone to future stains.

• Don’t leave plastic chairs wet – Always dry them to prevent mold or water marks.
