If you experience condensation on the exterior or interior of your window and door surfaces, you may notice discoloration along the lower parts of your wood windows or doors. This discoloration is likely the result of mildew or water stains. Mildew is a fungus that thrives on warmth and moisture, but can flourish to some extent under all climatic conditions. Mildew growth is usually brown or black in color, and for this reason, may be mistaken for dirt. Follow the instructions below to care and maintain your Marvin products.
