Using this trash bin cover is easy. Just slip it over your 41 - 50 - gallon round trash bin. The elastic holes on both sides will help it stay in place. For best results, make sure the bin is clean before putting on the cover. When it comes to cleaning, you can simply throw it in the washing machine and tumble dry on low heat. Avoid using harsh detergents as they may damage the spandex material. Also, don't expose it to direct sunlight for long periods as this can fade the navy blue color. Keep it away from sharp objects to prevent tears. With proper care, this cover will serve you well for a long time at your events or in your home.
