Fiberglass doors are durable, environmentally friendly, and energy efficient. They come in a variety of sizes, colors and styles and are even available in garage-door models. However, just like wood and steel doors, fiberglass doors are susceptible to dust, dirt and grime buildup. They require a cleaning method that won’t damage the fiberglass and won't leave a residue.
