Outdoor solar lights are one of the most practical and energy-efficient ways to brighten gardens, patios, and pathways. Over time, however, dust, pollen, and weather residue can reduce their brightness and shorten their lifespan. Proper maintenance ensures your lights keep shining at full capacity all year long.
At FEIDONG, we specialize in durable and weather-resistant Solar Outdoor Lights that require minimal upkeep. Still, a little care goes a long way — and this guide will show you exactly how to clean outdoor solar lights safely and effectively.

1. Why Cleaning Solar Lights Matters

Even though solar lights are designed for outdoor use, exposure to the elements gradually affects their performance. Dirt, rain spots, and oxidation can block sunlight from reaching the panel and weaken the light output.

Main Reasons to Clean Regularly

1. Restore Brightness
   Dust or cloudy residue on the solar panel reduces sunlight absorption, making the light dimmer at night. Cleaning restores up to 30–40% of lost brightness.

2. Extend Lifespan
   Regular cleaning prevents water stains, corrosion, and insect buildup that can damage wiring or seals.

3. Maintain Energy Efficiency
   Clean panels charge faster and store more power during the day, which means longer illumination hours after sunset.

4. Preserve Appearance
   Keeping your lights clean enhances the beauty of your outdoor space and protects your investment.

At FEIDONG, all our solar lights are built with IP65+ waterproof protection and anti-corrosion coatings, making cleaning easy and worry-free.

2. Step-by-Step Guide: How to Clean Outdoor Solar Lights

Cleaning solar lights does not require special tools — just gentle materials and a few careful steps.

What You’ll Need

• Soft cloth or microfiber towel

• Mild dish soap

• Warm water

• Soft-bristle toothbrush

• Sponge

• Screwdriver (for removing covers, if needed)

Step 1: Turn Off and Detach the Solar Light

• Switch off the light using the power button (usually located near the solar panel or under the light body).

• Remove the light from its mounting post or wall if possible. This allows for more precise cleaning and prevents electrical damage.

• Place it on a soft, flat surface for cleaning.

Step 2: Clean the Solar Panel

The solar panel is the most critical part of your light. Dirt or haze here can block sunlight and reduce energy absorption.

Instructions:

• Dip a soft cloth in warm soapy water and gently wipe the surface of the panel.

• Avoid abrasive cleaners or scrubbing pads — they can scratch the panel.

• Use a soft toothbrush to clean corners or textured areas.

• Rinse with clean water and dry with a microfiber towel.

Tip: If your panel looks cloudy or faded, lightly polish it with a small amount of glass cleaner or a mix of vinegar and water (1:1 ratio).

Step 3: Clean the Light Housing and Lens

The body and lens often collect grime, insects, and mineral deposits.

How to Clean:

• Use a damp sponge to wipe the housing and lamp cover.

• For stubborn dirt, add mild soap but avoid soaking the entire unit.

• Check for cracks or loose seals that could let in moisture.

• Rinse lightly and dry thoroughly to prevent watermarks.

Note: For FEIDONG’s solar lights with glass lenses, avoid extreme temperature water to prevent cracking.

Step 4: Check the Battery Compartment

Even though solar lights are sealed, moisture or dust can sometimes reach the battery area.

• Open the battery cover gently with a screwdriver.

• Remove the battery and wipe the compartment with a dry cloth.

• If corrosion is visible, use a cotton swab dipped in vinegar to clean the metal contacts, then let it dry completely before reinserting the battery.

FEIDONG Tip: Replace rechargeable batteries every 12–18 months to maintain maximum brightness and battery efficiency.

Step 5: Reassemble and Test

Once all parts are clean and dry:

• Reassemble the unit and tighten any screws.

• Turn on the power switch.

• Place the light in direct sunlight for several hours to recharge fully before testing at night.

If the light still appears dim, double-check for debris near the solar sensor or replace the old battery with a new one.

3. Maintenance Frequency and Seasonal Care

How often you clean solar lights depends on your environment and weather conditions.

Additional Maintenance Tips

• Trim nearby plants to prevent shading of the solar panels.

• Avoid pressure washing; water pressure can damage seals.

• Store properly if not used during cold months — remove the battery and keep lights in a dry location.

• Inspect mounting hardware periodically for rust or looseness.

4. How FEIDONG Designs Simplify Cleaning
