Bifold doors are generally considered to be low maintenance, especially when compared to other types of doors or windows. However, like any other type of door or window, they do require some level of upkeep to keep them in good condition. One of the main maintenance tasks for bifold doors is regular cleaning to remove dirt, dust, and grime from the frames, tracks, and glass panels. This can be done with a soft cloth or sponge and a mild detergent or glass cleaner.
