  • Solar Pool Lights: Pool lights are completely submerged in water, so if they’ve become yellowed over time, cleaning them with this method will restore them to their original color.
  • Solar Fence Lights: Fence lights are completely exposed, meaning they can easily become dirty or yellowed over time. Cleaning them with this guide will bring their color back to life.

Yellowed Solar Light FAQ

Why do solar lights turn yellow?

Solar LightsYellowing is caused by years of exposure to the sun. The plastic on solar lights can yellow anywhere from one year to three depending on how much time they spend in direct sunlight vs under a covered area etc.

It’s not harmful, but it certainly isn’t attractive!

What causes some types of solar light bulbs to turn more quickly than others?

Manufacturing quality – if there are any flaws or impurities during manufacturing, this could lead to early oxidation/yellowing. Some manufacturers will use different colors for lamps that oxidize faster (for example an orange lamp), so you don’t end up with all your lights looking bad after only a few months. This way you’ll know which ones need special attention and won’t be caught off guard.

Can I use a different cleaning solution?

If you don’t have white vinegar or dishwashing soap, you can try using a 50/50 mixture of bleach and water as an alternative. Be very careful when using this mixture – it’s highly corrosive! Wear goggles and a mask, if possible. If droplets of bleach enter your eyes, mouth, or nose, the lining of these regions may be irritated.

While hydrogen peroxide can be used as an alternative to white vinegar, it is not recommended. Hydrogen peroxide is a bleaching agent and can damage the plastic on solar lights. If you choose to use this solution, test it in an inconspicuous area first to make sure there is no adverse reaction before proceeding with full cleaning.

What is yellow oxidation?

Yellow oxidation is when the plastic on solar lights turns a yellowish-brown color. It’s unsightly and can make your solar light look old and dingy, but don’t worry because it’s easy to fix!

How long will the oxidation removal process take?

As long as it takes for the solution to break down and wipe off the oxidation! If you have a lot of lights, this could take 30-60 minutes or more.
