If you’ve ever owned solar lights, then you know the problem of yellow oxidation. This is when the plastic on the light starts to turn a yellowish-brown color, and it’s not attractive at all. The good news is that you can fix this problem using a homemade oxidation-removal solution.
If you follow these steps, your solar lights should look good as new!
Tools and Materials Needed
- Bucket or container large enough to submerge the light in
- Dishwashing soap
- White vinegar
- Water
- Scrub brush or toothbrush
- Soft cloths
- Qtips (optional)
- Sunshine (optional)
Step by Step Guide to Cleaning Yellowed Solar Lights
Step One: Fill Your Bucket
Fill your bucket or container with warm water and add a couple of drops of dishwashing soap. Swirl the solution around until it’s sudsy.
Step Two: Add White Vinegar to The Solution
Add white vinegar to the solution until it’s about halfway full. Again, swirl the mixture around until everything is combined.
Step Three: Wipe the Solar Light
Wipe the solar light with the soapy water/vinegar solution. The solution will eat away at the oxidation, breaking it down and allowing you to wipe most of it off. Take extra care to avoid getting water inside the lights.
Step Four: Use a Scrub Brush
Use a scrub brush or toothbrush to clean the light, making sure to get into all of the nooks and crannies. Be careful not to damage the light in any way.
Step Five: Dry
Pat the solar light dry with a soft cloth. If any stubborn areas still need cleaning, use a Q-tip dipped in a vinegar solution.
Step Six: Use as Normal!
Use your solar light as normal after cleaning it. It should look just like new again!

Summing Up
Yellowed plastic solar light covers are one of the most fixable cosmetic problems in the garden. UV exposure oxidizes the plastic surface over time, creating a cloudy yellow film that dims the light output and looks tired. Headlight restoration products, plastic polish, or a simple baking soda and toothpaste paste can restore clarity in most cases. For badly degraded plastic, a coat of UV-protective clear coat after polishing slows further yellowing significantly and extends the time before you need to restore them again.
