Flags will last various amounts of time depending on how it is used, how much sun it receives, and overall how it is treated. The majority of enemies for a flag are wind, water, sun, and carelessness. Neither you, nor we can control the weather, but you can take care of your flag and lengthen its life. Occasional washing in warm mild-detergent water will prevent dirt and pollutants from attacking the fabric. To prevent mildew, let your flag dry thoroughly before storing it. Have your flag repaired at first sign of fraying, don’t wait for it to be blown to shreds. Continuous day and night display will shorten a flag’s life. If your flag is not illuminated at night, you should consider taking it down to appreciably lengthen its life.
