Wet Outdoor Cleaning Method
Cleaning supplies:
• Water
• 5-gal bucket
• Automotive detergent
• 4' to 8' telescoping, soft automotive brush with bristles that are light to medium in
rigidity
• Several soft terry cloth towels
Cleaning process:
1. Mix the automotive detergent and cold water in the 5-gal bucket at 1 oz detergent
to 1 gal of cold water. Distilled water is preferred, but not required.
2. Dip the brush in the bucket of soapy water.
3. Using brush strokes, wash the LED panel from top to bottom.
Note: Using a soap-dispensing brush with a low soap-to-water ratio eliminates
excess soap residue.
4. Thoroughly rinse the LED panel face with cold water under low pressure.
5. Use a soft, dry terry cloth to dry and remove any excess water.
6. Check the light sensor and verify it is visible through the mask of the LED panel.
